Show The species of Lagochilus recorded from the Malay region are very puzzling and I think Dr. Moellendorff was quite right in c escribing as L. rollei the form that I noted (under the name of • townsendi) from Kelantan. The nearest ally of L. kobelti appears to be L. townsendi Crosse; I have not seen an authentic specimen of that species, but have compared the form now described wi i the description and figures given by Crosse and with a specimen collected by Herr Grubauer, from whose collections i. Moellendorff has recorded X. townsendi as the only species ound. The shell I now name is a trifle smaller and more elevated in proportion to the breadth, and the umbilicus is nailower. It may be noted that the reference to Crosse's original paper in the ‘ Journal de Conchyliologie ' should be to p. 200 and not p. 208 as given by De Morgan and Dr. Moellendorff in their papers on the Perak fauna. I have named the form after Dr. Kobelt as a tr ifling recognition of his recent study of the Cyclophoridse. D itropis c a v e r n s , sp. nov. (Plate XX. figs. 17-19.)

Gunong Inas, Perak. Recently when cataloguing (J. Malac. ix. p. 61) a collection of shells from Kelantan, I gave the names of Cyclopiiorus saturnus Pfr. and borneensis Mete.: both the forms then recorded have occurred in the present collection, and I have therefore again considered the identifications. Both, according to my present view, are erroneous, and the group is a very difficult one. The present species, which I regard as a form of C. malayanus, was then named C. saturnus, and the next species was called C. borneensis. C yclophorus tuba (Sby.). Cyclostoma ^ 6«Sowerby, Proc. Zool.
