178 PEOCEEDINGS OF THE MALACOLOGICAL SOCIETY. 



2. Kaliella Salicensis, n.sp. PI. XIV, Fig. 3, 



Shell perforate, conical ; sculpture irregular, coarse, transverse 

 ribbing ; periostracuni umber-coloured. Spire conic, flat-sicled ; suture 

 very shallow ; whorls 7 ; sides rather flat. Aperture quadrate, straight 

 below ; peristome suboblique ; columellar margin reflected. Size : 

 alt. 3, maj. diam. 2"8mm. 



The whorls of this species do not increase in breadth so much 

 as in K. Barraclqmrensis •, the fine, regular, transverse sculpture is 

 absent, rougher irregular ribs taking its place. The base of the 

 Ceylon shell is not so broad, in proportion to the height of the spire, 

 as in the Bengal species. 



Hah. — Uda Pussellawa (H. B. Preston). 



3. Lamprocystis ? Sinhila, n.sp. PL XIV, Fig. 2. 



Shell globose, solid for its size, scarcely umbilicated ; sculpture 

 smooth, with a strong periostracum ; colour? (bleached). Spire low, 

 depressedly conic, apex very blunt; suture shallow; whorls 5, 

 closely wound, regularly increasing. Aperture narrowly lunate, 

 vertical ; peristome simple ; columellar margin suboblique. Size : 

 maj. diam. 3"6 ; alt. axis 1 mm. 



Hah. — Uda Pussellawa, Ceylon (H. B. Preston). 



This species very probably belongs to the Zonitidoe, but there 

 is no certainty with regard to these small foiins ; it is very desirable 

 to procure examples of the animal. It will be a long time before 

 the micro-helices are better known. In some cases they are the 

 young of larger species, but that does not detract from their interest. 



4. Lampeocystis ? Nuwaeaensis, n.sp. PL XIV, Pig. 4. 



Shell very depressedly globose, rather openly umbilicated ; sculpture, 

 very fine longitudinal striation, crossed by irregular lines of growth ; 

 colour pale horny-grey. Spire very low ; apex flatly rounded ; suture 

 well impressed ; whorls 5-s-, sides rounded. Aperture narrowly lunate, 

 vertical ; peristome simple. Columellar margin sinuate. Size : major 

 diam. 4; alt. axis 1-9 mm. 



Sab. — ISTuwara Eliya, Ceylon (Dr. Leith). 



This shell, which is a Avell-marked form, came into my hands by 

 purchase from Mr. Geale, who, I believe, had all Dr. Leith' s collection 

 to dispose of.
