Pease described some 500 species of mollusks from the Indo-Pacific region. Of these, some 380 were shell-bearing. Type material was located for all but 42, consisting of syntypes, some previously figured or measured, which have hitherto been re-garded as holotypes or selected as lectotypes. Many lectotypes are chosen here and illustrated for the first time. All of the holotypes and lectotypes in the Mu-seum of Comparative Zoology are figured. INTRODUCTION The original William Harper Pease col-lection is in the Museum of Comparative Zoology, Harvard University. After Pease died in 1871, his collection was sent to Boston to be sold "entire." It was offered to a Mrs. Witthaus of New York for $3,000. In a letter to John Gould Anthony, Curator of Mollusks at the Museum of Compara-tive Zoology, she said that she had seen the collection and found it to be damaged by careless packing. She arranged to pur-chase only the specimens she wanted, the larger pretty shells (R. D. Turner, personal ' Museum of Comparative Zoology, Harvard Uni-versity, Cambridge, Massachusetts 02L38. communication). The remaining collec-tion was sold to Louis Agassiz, director of the Museum of Comparative Zoology. Most of the types and smaller specimens were carefully glued on pieces of glass or slate for exhibition by curator Anthony. This process, as well as the formula for the glue, is included in Turner's (1946) definitive biography of Anthony. In this century, the shells were removed from the plaques by William J. Clench, cataloged, and num-bered. Each lot is usually accompanied by labels in Anthony's distinctive and accu-rate calligraphy as well as one penciled on a scrap of paper by Pease. There is a type-written list of the collection in the De-partment of Mollusks compiled by Wil-liam F. Clapp (1923, Dept. Library, no. 5912), "copied from Pease catalogue writ-ten on loose sheets of stationery." Aside from the type material, and that collected by Andrew Garrett, most of the lots have locality data that are so general as to ren-der the specimens useless for study. The Witthaus material became the property of Vassar College, Poughkeepsie, New York, and was presented to the Museum of Com-parative Zoology in 1944. Solem (1976: 9) took such a dim view of the Pease collection that he virtually ignored it when monographing the En-dodontoid Land Snails from Pacific Is-lands, preferring to select lectotypes from any other collection that had Pease ma-terial, such as the National Museum of Natural History, Washington, D.C., or the Bernice Pauahi Bishop Museum, Honolu-Bull.
