generative organs, the new species differs from M. Javanica bj' its 

 small vestibule, which is lai'ge, triangularly rounded in Javanica', 

 that species has a much smaller and pyriform receptaculum seminis, 

 and the penis is quite diifeient in shape, the vaginal part is not 

 swollen, etc. Though the specimens varj' in colour, the younger 

 ones being more distinctly marked with black, they will, however, 

 probably belong to one and the same species, the differences are 

 certain 1 J' not stronger than those figured by Simroth (loc. cit., pi. vii, 

 figs. 6«, 6^) as the adult and young of Parmarion Weheri.

 The species seems to be somewhat variable, the whorls of the specimen 

 are a trifle narrower than the majority of those I received from 

 different sources from Java, but it agrees rather well with a not yet 

 described var. rufula, Boettg., which is slightly smaller and darker 

 than those denoted as typical. 



12. Plectotropis Tenggekica, n.sp. PI. X, Figs. 9-11. 



Shell comparatively narrowly urabilicated, thin, fragile, yellowish- 

 brown, depressed, spire conoidal, periphery with an obtuse angle or 

 keel, obsolete near aperture, whorls 5^, rather regularly increasing, 

 last one slightly bi-oader, moderately convex, with a shallow sutiu'e, 

 slightly descending towards the aperture. Sculpture consisting of 

 fine, rather irregular plicae, the whole shell with short hairs. Aperture 

 moderately oblique, bi'oadly lunar, peristome regularly rounded (not 

 quite developed), coluraellar margin reflected at and partly covering 

 the umbilicus. 



Diam. maj. 10, alt. 6-5 mm. ; apert., alt. (diagonally) 4*5, 

 lat. 4 mm. ; diam. of umbilicus, 2 mm. 



Hah. — Nongkodjadjar, January, 1911. Two specimens. Type in 

 my collection, cotype in Leyden Museum. 



Though these specimens aie not quite developed, the peristome 

 being still thin and fragile. I thought it fit to name them. The 

 nearest ally is P. Schepmani, ]\llldff'. (Nachrichtsbl. d. D. Mai. 

 Gesellsch., 1897, p. 68), by its narrow umbilicus; compared with 

 a cotype presented by Professor Boettger, who originally named but 

 did not describe it, the shell is higher, the keel more obtuse ; that 

 species is conspicuouslv spirally striated, and shows no traces of 

 hairs or even scars. P. Wi)iteriana and Sutnatrana are still more 

 remote.
