174 F. Stoliczka — Notes on terrestrial Mollusca. [No. 2, 



only species which extends along the Southern slopes of the Hima- 

 layas westwards into the Sutlej valley. 



As no anatomical account has yet been published of any of the 

 Indian species, I shall give a few details of CI. PhiUppiana which, 

 with CI. hidbus, ( ? vespa), and a small form allied to PhiUppiana } 

 represents a peculiar little group of vespiform Clausilice from the 

 neighbourhood of Moulmein. 



Clausilia [Phedusa] Philippiana, Pfr., pi. vi, fig. 7-10. 



Mon. Hel., vol. ii, p. 423 ; Kiister. Sysfc. Conch.- Kabinet, Clausilia, p. 100, 

 pi. xi, fig. 7-9. 



Without Kiister's figure it would be difficult to identify Pfeiffer's 

 species, that author's description being in several respects barely 

 sufficient. Pfeiffer says regarding the 6 whorls il primi 3 palanius- 

 culi ;" this is strictly speaking not the case ; it is the apex which is 

 invariably obliquely flattened or obtuse, but all the whorls are 

 distinctly convex, and the three upper ones almost more so than the 

 following. The top, or embryonal whorl becomes quite solid in 

 adults. Further on, Pfeiffer says : " plica subcolumellaris immersa," 

 while that fold is perfectly distinctly traceable in the aperture. 



There are 7 or 8 palatal ribs on the outer lip, the uppermost 

 below the suture is the longest, the following short. The lower 

 palatal plaits become less distinct in old specimens, than they are 

 in the adolescent horny and transparent shells, but they never 

 appear to become obsolete. The other characters relating to the 

 structure and the dimensions, noted by Pfeiffer, agree well with 

 the Moulmein shell, except that the oblique longitudinal diameter 

 of the aperture is rarely 7 m.m. ; usually it is only 6£ m.m. in speci- 

 mens the total height of which is 21 m.m. Pfeiffer's reference to 

 the relation of CI. PMlippiana with insignis is not well chosen ; few 

 shells could be more different than these two ; but judging from 

 the description of Gould's CI. vespa, this form must be very closely 

 allied to PhiUppiana. The description is brief, but there is strictly 

 speaking nothing in it which could not equally well apply to the 

 last named species. 



A very closely allied species has also lately been obtained by Mr. 

 Theobald at Nattung, on the Attaran river, near Moidmeiii.
