The Perak species does not, as I have stated formerly, belong to Subulina, the columella only being slightly twisted, not truncated, but to the genus or subgenus Prosopeas, constituted by Moerch for S. haughtoni and S. roepstorfi of the Andamans. Stenogyra swettenhami, de Morgan, Bull. p. 41, t. ii. fig. 6, seems to me only a slight variation of T. tchehelense. 35. OPEAS GRACILE, Hutt. Bukit Pondong (Hungerford). 36. RHODINA PERAKENSIS, de Morgan. Rhodinaperukensis, de Morgan, Le Nat. 1885, p. 68 ; Bull. p. 42, t. ii. fig. 9 ; v. Molldff. 1. c. p. 305. Mt. Tchora, Kinta valley (de Morgan). I must confess that even the more complete description and the figure given by the author in his second memoir has not enabled me to form a decided opinion on this alleged new genus. De Morgan calls the " columellar lip " spiral, reflex, and very prominent ; the figure shows a sort of spiral lamella obliquely running from the columella into the aperture, a formation which indeed resembles somewhat the columellar lamella of Rhodea. This is, however, the only resemblance to the American genus which this curious shell presents. Fam. PUPID^E. 37. P U P A (BOYSIDIA) PALMIRA, Stol. Pupa (Scopelophila) palmira, Stoliczka, J. As. Soc.
