Introduction
QUEENSLAND FAUNISTIC RECORDS PART IX
A SECOND COLLECTION OF
OPISTHOBRANCH MOLLUSCS
FROM QUEENSLAND
As in the previous paper (Kenny, 1960), complete synonymy has not been listed for the species recorded in this list. Instead, recent and readily available references have been given. The classification used is basically that of Odhner (1936).
Most specimens listed in the 1960 report had been collected in southern Queensland, but the present collection is predominantly from tropical Queensland. The two collections add up to more than 440 specimens including 5 8 species. Many species, previously recorded from Queensland, have not been noted from these collections and almost lfcllf the species listed here were not recorded from the 1960 collection.
From this collection, one specimen of each species listed has been retained at the University College of Townsville. The remaining material and the specimens from the 1960 collection have been housed at the Queensland Museum, Brisbane.

Previously South Australia, New South Wales (Allan, 195 0); Victoria (Burn, 19661); southern Australia (Burn, 1966d).
Family AGLAIIDAE
Aglaia cyanea (Martens), 1880, as Doridium, p. 738; Allan, 1950, p. 2 17, Figs. 3-5.

One, Low Is. (15 /viii/63): two. Green l. (5/v/b3). in coral reef tlat lagoons.
Previously E. Africa (Iredale and tlktllichael, 1962): New South Wales, Victoria, Queensland (Burn, 1966/) as Doridiunz.
Order ANASPIDEA Family APL YSIIDAE
Syphonota geographica (Adams and Reeve), 1850, as Siphonotus, Pt. 3, p. 44; Baba, 1955, as Paraplysia, p. 39, Pl. 1, Fig. 2, Text-fig. 3.
One, Cairns Harbour ( 4/ix/61) dredged; one, Sarina (6/xi/63) sandy beach; one Townsville Harbour (27 /ix/66) under rocks on breakwater near low water springs.
Previously Japan and Indonesia (Baba, 195 5 ); circumtropica1 (Eales, 1960). Eales (1960) clearly states the synonymy of Paraplysia geographica with this species by listing Baba's ( 195 5 ) illustration. Baba, however, designates the illustration as P. geographica scripta Bergh 1905 . The description and text-figure given by Allan ( 195 0) for P. piperata Smith suggest that this is another synonym.
Aplysia dactylomela Rang, 1828, p. 56, Pl. 12; Baba, 1949, p. 124, Pl. 2, Fig. 6, Text-fig. 2; Eales, 1960, p. 307, Figs. 1-8.
Numerous specimens, various dates 196 1-66, from Magnetic 1., Townsville Harbour, Cairns Harbour, Port Douglas, various beaches Cairns south to Mackay.
Previously worldwide in warm seas (Eales, 1960), Queensland (Burn, 1966b ).
Complete synonymy is listed by Eales (1960) and discussed by Kay (1965). One of the Townsville Harbour specimens conformed to the colour pattern shown by Baba (1949), being a bright pink with purple markings, but all other specimens tended to be brown or olive green.
Aplysia extraordinaris Allan, 1932a, as Tethys, p. 3 19, Pl. 35, Figs . 7-8; Eales, 1960, p. 3 12, Fig. 22.

Previously Japan (Baba, 1949); circumtropical (Kay, 1965 ) as D. scapula; Caroline Is. , Guam and Palau I. (Marcus, 1965 ); New South Wales (Allan, 195 0).
Although this species is frequently listed as D. scapula (Martyn, 1784), it has been pointed out by Marcus (1965 ) that this name is invalid as Martyn's publication has been rejected by the International Commission on Nomenclature. Kay (196S) has reviewed the synonymy of the species.
Bursa tel/a /eachii Blain ville, 18 17, p. 138; Baba, 1949, as Notarchus, p. 128, Pl. 5, Fig. 19, Text-figs. 12, 14; Allan, 1950, p. 2 15.

Allan (1947) has commented on synonymy. It seems probable that Discodoris whitleyi Allan ( 193 2b) is a further synonym.
Trippa intecta Kelaart, 1859, p. 302; Allan, 1947, p. 451, Pl. 42, Figs. 8-10.
One, Townsville Harbour ( 14/ix/62) among algae on breakwater at low water; two, Magnetic I. (20/vii/63) among coral rubble; two, Low Is. (17/viii/63) on reef flat, low water neaps.

Previously Celebes (Bergh, 1905 ); Cape Leveque, Western Australia (Allan, 1932b ); Queensland (Kenny, 1960).
Allan ( 1932b) has discussed the relationship of this species with other Australian records from this genus.
The 1963 specimen was observed spawning both in the field and in the aquarium. The egg mass consisted of a speckled pink ribbon'like spiral of three whorls, overall size seven by eleven em, 15 to 18 mm wide, and attached to glass aquarium wall gave the impression of a folded translucent curtain (see Fig. 1 d).
Platydoris scabra Cuvier, !804a, p. 466; Allan, !932b, asP. iredalei, p. 89, Pl. 4, Figs. 3-4, Pl. 5, Fig. 3.

Caroline Is., Bikini Atoll (Marcus, 1965). Allan (1932b) discussed the similarities and differences between P. scabra, P.
coriacea, Abraham 1877, and P. iredalei and Marcus and Marcus (1960) have listed the synonymy. As the present collection includes material ranging through almost all the colour and superficial variations noted for the three species, the Cuvier name has been used here. Kenny (1960) used the Allan name.
90 A SECOND COLLECTION OF OPIS THOB RANCH MOLLUSCS
Family HEXABRANCHIDAE
Hexabranchus marginatus ( Quoy and Gaimard), 1832, as Doris, 2: p. ISS, Pl. 17, Figs. 1-S; Allan, 19SO, as H. imperialis Kent, p. 223, Pl. 28, Fig. 2.

The identity of the various specimens of Hexabranchus that have been recorded from various areas of the Indo-Pacific region and the associated synonymy are somewhat confused (see Iredale and McMichael, 1962).
Family DENDRODORIDIDAE
Dendrodoris nigra (Stimpson), 18SS, as Doris, p. 380; Baba, 1949, p. 1S4, Pl. 26, Figs. 88-89.

The present series includes the previously recorded variation and specimens similar to those depicted by Baba (1949), Pl. 26, Fig. 99 and Bergh (1905), Pl. 2, Fig. 14. Burn (1957, 1965) has commented on the occurrence of these colour varieties in Victoria and in the Sydney area.
Dendrodoris gemmacea ( Alder and Hancock), 1864, as Doridopsis, p. 126, Pl. 31, Figs. 4-7; Baba, 1949, p. ISS, Pl. 27, Fig. 100.

.
The colouring of these specimens conforms with the comments made by Kenny (1960).
Dendrodoris tuberculata ( Quoy and Gaimard), 1832, as Doris, p. 248, Pl. 16, Figs. 1-2; Allan, 1932b, as D. morulifer, p. 99, Pl. s, Figs. 1-2; Baba, 1949, p. IS4; Baba, 1955; p. 55, Pl. 1 9, Figs. 51-52.
One, Low Is. (17 /viii/63) on reef flat near low water neap. Previously Queensland (Allan, 1932b) as D. morulifer; Indo-Pacific and Japan
(Baba, 1949, 1955). This specimen was d istinctly olive and brown in colour, rather than the bright
green depicted by Baba, but shows the characteristic white markings under the mantle. Pruvot-Fol (1934) comments on the resemblance of D. morulifer, Allan, to
D. tuberculata, and Burn (1962b) has placed Allan's species in the synonymy of D. tuberculata.

Wales (lredale and McMichael, 1962; Bennett, 1966). Bennett ( 1966) has commented on synonymy and pointed out that many past
records of G. lineatus, from Australian waters, should be referred to this species.
Spawning
The 4 species for which egg masses were observed (Pleurobranchus hilli, Pleurobranchus mamillatus, Chromodoris lineolata, Asteronotus cespitosus) were all collected in the Townsville, Magnetic Island area and all spawned in the July, August period. This period of the year is the time of lowest inshore sea temperatures in this area. The sea surface temperatures outside the Townsville harbour breakwater recorded during July and August range from 20.4°C to 22. 5°C (27 readings at various dates).
94 A SECOND C OLLECTI O N OF OPISTHOBRANCH MOL LUSCS
Zoogeography
Of the 49 species listed in this paper, 23 have not previously been reported from Queensland and 9 of these are new records for Australia. This collection plus the recorded geographic distribution of these species from the literature suggests that the opisthobranch fauna of the Indo-West Pacific region is relatively uniform (see also Kenny, 1960). Of the species listed, 4 can be described as widespread tropical forms, 22 as having a wide IndoPacific range, 14 as occurring throughout the western Pacific from eastern Australia to Japan and 9 noted only in the south-west Pacific area.
Acknowledgments
The author is indebted to the members of staff and students of the Townsville University College who assisted with the collection of much of the material. The Zoology Department, University of Queensland, and Dr. J. Barnes (Cairns) provided several specimens.
Special thanks are due to Mr. R. Burn (Honorary Associate in Conchology, National Museum, Melbourne) for his considerable assistance with literature, and for reading and criticizing the manuscript.
