Show 1904.] ON INDIAN AND BURMESE LAND-SHELLS. 441 4. Descriptions of Indian and Burmese Land-Shells referred to the Genera Macrochlamys, Bensonia, Taphrospira, (gen. nov.), Microcystina, Euplecta, and Polita. By W . T. B l a n f o r d , C.I.E., L L .D ., F.R.S., V .P .Z .S . [Received October 31, 1904.] (Plate X X V * ) The following pages contain diagnoses of several Indian land-shells that are believed to be undescribed. The majority belong to the genus Macrochlamys, and have been met with in the course of an attempt at monographing the forms found in the Empire of British India. Only those kinds have been described of which the localities are believed to he accurately ascertained, which are sufficiently distinct to render it probable that they may be recognised from their description, and of which type specimens are available for deposit in the British Museum. Some of the specimens are from my own collections made in India and Burma, others are from the British Museum accumulations, whilst for others I am indebted to Colonel Godwin-Austen, Colonel Beddome, and Mr. Hugh Fulton. I have to acknowledge the valuable assistance and advice of Mr. E. A. Smith in my examination of the British Museum specimens. B ensonia n e p a len s is , Nevill MS. (Plate XXV. fig. 1.)
