DESCRIPTION
Introduction to the seashells of Texas. Outline of the book, Encyclopedia of Texas Seashells, written by Wes Tunnell, Jean Andrews, Noe Barrera and Fabio Moretzsohn, with contributions by Kim Withers and David Hicks. The book was published by Texas A&M University Press in 2010 (http://www.amazon.com/Encyclopedia-Texas-Seashells-Identification-Distribution-ebook/dp/B0087DHJ88/ref=sr_1_1?ie=UTF8&qid=1409861431&sr=8-1&keywords=texas+seashells). The book discusses and illustrates 900 marine mollusks from Texas. The book covers the use of shells in Texas history, the history of malacology in Texas, the ecology and habitats of marine seashells, shell collecting, features of seashells, and discussion of 900 species (nearly all that are known from the region). Each species is illustrated in color photographs, and there is information about its taxonomy, popular name, distribution, size, description, habitat, remarks, and synonyms. There is a checklist with abbreviated information, followed by a glossary (over 900 entries) and extensive bibliography (750 references). A smaller version with the 300 most common species will be published in Dec. 2014 (Texas Seashells, A Field Guide) by TAMU Press.TRANSCRIPT

Reasons for increase in species• Andrews included only self-collected species• More comprehensive coverage (to deep Gulf; tropical
species)• Micromollusks (about 1/3 of species)• New records and range extensions• Dee water and rare species• Shell-less mollusks• Non-indigenous species spreading into the Gulf of
Mexico• New species descriptions
