 the base of the shell, in which region the latter are more numerous 

 and less distant : whorls 4|, somewhat inflated ; sutures deeply 

 impressed; umbilicus wide and deep ; ])eristoine continuous, thick- 

 ened, slightly reflexed and double throughout ; aperture circular. 



" Altitude 2"5, diam. maj. 2 mm." 



Hah. Ceylon: Kirklees Estate, Uda Pussellawa (Ogden). 



" In general outline and sculpture this species may be compared 

 with C. serendibense, Preston ; the whorls of the present form are, 

 however, more tumid, the umbilicus is wider and the peristome is 

 throughout thickened, reflexed and double, which is not the case 

 with C. screiidihease:' (Preston.) 



21o. Cyathopoma perconoideum, Presfon. 



Cyathopoma per conoideum, Preston, Rec. Ind. Mus. iii, 1909, p. 139, 

 pi. 22, fig-. 9. 



Original description : — " Shell elongately conic, white, bearing 

 traces of having been covered with alight yellowish brown perios- 

 tracum ; whorls 6, convex, sculptured with several spiral lirse ; 

 sutures impressed ; umbilicus very narrow and partly concealed by 

 the outward expansion of the peristome; peristome continuous, 

 reflexed in the umbilical region and at the base, simple at all other 

 points ; aperture almost circular. 



"Alt. 2, diam. 0*75 mm." 



Hah. Ceylon : Bandarawella, prov. of Uva. 



" Allied to Cyathopoma conoideum, Sykes, but more elongately 

 conoid in form ; the spiral lirje are also much more numerous than 

 in that species. The timbilicus is narrower, being reduced in the 

 present form to a mere chink ; the aperture, moreover, is more 

 nearly circular than in C. conoideum.'" {Preston.)
