314 CLAUSILIIDiE, 



short, parallel with the suture ; the .second very short, parallel 

 with the upper; the third louger and oblique, entirely visible from 

 the aperture. Peristome slightly thickened, not expanded and 

 but little reflexed, the parietal margin not solute, without sinus at 

 the upper parietal fold, columellar margin curved, obhquely 

 descending, basal margin curved, outer margin a little inflexed. 



Long. 16, diam. 4*2 mm. 



Hah. Burma : Arakan. 



Type in Mr. Lemau's collection. 



Two specimens in the late Colonel Beddome's collection, now 

 in the possession of Mr. G. C. Leman, were labelled C. arakanensis, 

 but upon examination they proved to be quite distinct, and in 

 basing a new species upon them I have much pleasure in asso- 

 ciating with the new form tlie name of Mr. Leman, who upon 

 several occasions has readily given me access to this important 

 collection, so rich especially in Indian and Burmese sliells. 



The new species, while allied to C. arajcanensis, may readily be 

 separated by its more convex spire, its more obtuse ape.\, and the 

 more closely coiled whorls, for although shells of 10 whorls of 

 C. arakanensis measure 17 nun. in length, C. hmani u ith 11 whorls 

 only attains lt> mm.; the shell, moreover, is striated, not ribbed. 

 The palatal plica? are also less in number, and instead of all being 

 parallel, the lowest is nearly vertical, and they are all much 

 nearer the aperture.

Range. India, Burma, China, Japan, Malay Archipelago. 



Clausilium attenuated below, tlie blade somewhat elongated and 

 dilated below. The palatal plica? varying in number, the upper 

 rather long. Lunula nearly always absent. The upper parietal 

 fold more or less oblique, subcolumellar fold hidden. Aperture 

 large, protracted below, the right upper margin always more or 

 less sinuate towards the upper parietal fold, the peristome strongly 

 expanded and reflexed. The shell has few whorls, usually an acute 

 apex, is corneous and more or less hnely striated.
