110 TROCEEDINGS OF THE MALACOLOGICAI, SOCIETY. 



ITah. — West Sumatra. 



Type in Mr. Sykes' collection. , 



Allied to C. Smithi, but not tubercled like that species. It is 

 smaller, the last whorl is not deflexed, not concave above the periphery, 

 and the peristome is thinner and not reflexed. 



Chloritis Sykesi, n.sp. PI. XIII, Figs. 10-1 Oc. 



Shell umbilicated, depressed conoid, pale corneous, fragile, trans- 

 lucent, shining under a velvety cuticle (Fig. 10c), finely striated, 

 covered with very short, crowded, pale bristles arranged in quincunx. 

 Spire subplane, apex sunk, suture impressed. Whorls 4J, convex 

 above, rounded at the side, slightly compressed below, obtusely 

 angulated round the moderate pervious umbilicus ; last whorl scarcely 

 descending, not deflexed in front, slightly dilated towards the mouth. 

 Aperture crescentic, little oblique, margins convergent ; peristome 

 thin, fuscous, shortly reflexed ; upper and outer margins arcuate, 

 basal forming an obtuse angle with the columellar margin, which is 

 nearly vertical, slightly dilated above, shortly ascending forward, 

 and slightly impinging upon the umbilicus. Diam, maj. 16-5, min. 

 14-5 mm. ; alt. 10 mm. 



Hah. — West Sumatra. 



Type in Mr. Sykes' collection. 



The present species resembles C. Fndidorfcri in contour, but is 

 a little more depressed, the hairs are much crowded, not tubercled ; the 

 peristome is thinner, and the columellar margin less dilated. Compared 

 with C. Uveretti, the whorls are less tumid, and the umbilicus is wider. 

 Another ally is C. tahulnris, but that species is larger, less depressed, 

 darker in colour, the columellar margin is less oblique, the umbilicus 

 narrower, less obliquely excavated, and less angulated, while the 

 hairs are slightly less crowded. This and the preceding species were 

 kindly placed in my hands for description by Mr. Sykes. 



Chloeitis ecrychasma, n.sp. PI. XIII, Figs. 11-llc. 



Shell perforate, compressed conoid, pale corneous, rather thin, 

 translucent, finely striated, covered with very short, crowded hairs 

 arranged in quincunx (Fig. lie). Spire conoid, apex prominent, suture 

 impressed. Whorls 4 (the first two minutely granulated), convex 

 above, obtusely angulated at the perijiherj^ becoming rounded towards 

 the mouth, tumid below ; last whorl descending shortly, abruptly 

 deflexed in front below the periphery, gibbous and then narrowly 

 constricted behind the peristome. Aperture obovate, margins distant, 

 united by a somewhat solid callus on the parietal wall. Peristome 

 fuscous, a little thickened, shortly reflexed ; upper, outer, and basal 

 margins arcuate, columellar broadly dilated, more than half covering 

 the narrow perforation of the umbilicus. Diam. maj. 15, min. 13-5 mm. ; 

 alt. 1 1 mm. 



Hah. — Sjerah Island (? Sera), north of Tenimber. 



Type in my collection. 



I have adopted the MS. name C. enrychasnm, Boettger, under which 

 tlie shell was received by the writer from the late Bruno Strubell.
