1891.] THE SHELLS OF PERAK. 337 



Fam. Stenogyrid^. 



33. Hapalus jousseaumi, de Morgan, Bull. p. 24, t. i. fig. 2. 

 Ipoh, Kinta valley {de Morgan). 



34. Prosopeas tchehelense, de Morgan. 



Stenogyra tchehelensis, de Morgan, Le Natural. 1885, p. 69; 

 Bull. p. 40, t. ii. fig. 7. 



Stenogyra (Subulina) tchehelensis, v. Molldff. 1. c. p. 304. 



Stenogyra {Opens) 1 terebralis, Theob. (? n. sp.), G. Nevill, 

 Haiidl. Moll. Ind. Mus. 1878, p. 166. 



Bukit Pondong {Townsend, Hungerford) ; Mt. Tchehel, Pluss 

 valley {de Morgan). 



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. 



Rhodina perukensis, de Morgan, Le Nat. 1885, p. 68 ; Bull. p. 42, 

 t. ii. fig. 9 ; V. Molldff. 1. c. p. 305. 



Mr. 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.
