Found at the Lighthouse Avenue Goodwill: 1962 Golden Nature Series book Seashells of the World. In addition to the brilliant illustrations typical of the Golden Nature Guides, this book is a treasure chest of fantastic words.
Author R. Tucker Abbott, PhD is listed as Du Pont Chair of Molocology at the Delaware Museum of Natural History. Molocology doesn't appear in any of my dictionaries, but malacology is the study of mollusks, likely the synonym, though I like the look of all the Os in molocology.
A few great shell words from the California Province:
Purple Dwarf Olive, Kelp-weed Scallop, Cooper's Nutmeg, Haliotis Abalone, Chiton, and my favorite: Frilled Dogwinkle. If I find a dogwinkle on the beach, I will post a picture.
