Descriptions of a new genus and eight new species of eastern Pacific Fissurellidae, with notes on other species

Abstract: THE EASTERN PACIFIC FISSURELLIDAE are known chiefly through PILSBRY'S monograph in the Manual of Conchology (1890). More recently the species of the Panamic province were treated by KEEN (1958) and those of the northeastern Pacific in a dissertation by MCLEAN (1966). A comprehensive review of the entire family similar to that for the western Atlantic by FARFANTE (1943a, 1943b, 1947) is not available. Most of the genera discussed by FARFANTE are represented in the eastern Pacific and these papers are of considerable value for comparison. In assisting with the treatment of Fissurellidae for the forthcoming revised edition of "Seashells of Tropical West America," by Dr. Myra Keen, I have realized that there is a need for the description of a new genus and several new species. These descriptions are presented here. Five of the new species are from the tropical Panamic faunal province, while 3 are from the south temperate Peruvian province. Two of the Panamic species are from the Galapagos Islands, approximately 600 miles west of Ecuador. The 3 species from the Peruvian province are from the offshore Chilean island groups Juan Fernandez and San Felix. These islands bear much the same relationship to the Peruvian province as do the Galapagos Islands to the Panamic province. Many of the species are endemic. ODHNER (1922) listed 39 species from shallow water at the Juan Fernandez Islands, 50% of which were endemic. Very little is known of the offshore mollusks of the Chilean islands. The 3 species described herein result from collecting on the Anton Bruun Cruise 17 that visited these islands in July 1966. Institutions mentioned in the text and their abbreviations are as follows:
