SCHEPMAN : NON-llAKINE MOLI.CSCA FROM JAVA. 235 



One of tlie specimens, taken in November, is young, and the 

 hyponotura is but faintly spotted with blackish ; the iiotum is likewise 

 of a lighter colour than in the larger specimens. 



18. SucciNEA Javanica, n.sp. PI. X, Pigs. 12, 13. 



Shell ovate, with sliort spire, pellucid, amber-coloured. Whorls 

 about three, rather convex, but more flattened at tlieir upper part. 

 Sculpture consisting of numerous fine growth-lines, and at intervals 

 stronger ones, which have the character of folds, especially on the 

 dorsal side of last Avhorl, and more conspicuous b(;lo\v the suture; 

 moreover, the shell has a fine sculpture, only visible under a strong 

 lens or low power of the microscope, consisting of oblif|ue proti'active 

 and retractive lines, which intercross and give a dull appearance to 

 the shell ; last whorl rather oblique. Aperture oval, with a moderately' 

 sharp angle above, peristome thin. Columella foiining a blunt angle 

 with body-whorl, with a sharp edge from body-whorl to regularly 

 rounded basal margin ; no trace of umbilicus, the columellar margin 

 of body-whorl, with a narrow thin layer of enamel, more conspicuous 

 and circumscribed in its lower half, until the point of junction with 

 the basal mar<:in. 



Alt. y, lat. 00 mm. ; apert., alt. 6'5, lat. 3".5mm. 



J/ah. — Tuntang Kiver, Octobei', 1910. One specimen in my 

 collection. 



This species seems to be very different from S. ohena, \. Martens 

 (Ostas. Landschn., p. 387, pi. xxii, fig. 21), Avhich is much more 

 convex, less oblique, and has no peculiar sculpture. The only species 

 from the archipelago of wliich I find a description of such sculpture 

 i- .S'. solklula, Pfr. (Proc. Zool. Soc. Lond., 1849, p. 134), afterwards 

 <li<rribed and figured by Smith (loc. cit., 1887, }•. 518. fig. 1, woodcut, 

 and Christmas Island Monograph, 1900, p. o6, pi. viii, figs. 8, 9), but 

 in that sy)ecies the whorls are more convex below the suture, 

 accordingly the shell has a less elongated appearance, and the 

 columellar side is less angular at the point of junction of upper 

 part of columella and body-whorl. >S'. gracilis, Lea, which has been 

 recorded from Java wnth doubt, is quite different accoi'ding to Pfeiffer's 

 description (Mon. Helic, vol.ii, p. 518), and S. siihrugata, Pfr., which 

 might have a secondary sculpture, according to Pfeiffer (loc. cit., 

 vol. iii, p. 10), " vix nitidula, quasi pruinosa," is from Borneo, and 

 differs in many respects.

The specimens of this verv variable species are young, and only
