The majority of the specimens is sli^jhtly larger than v. M.MaENs' type, the larj^est having 

 a diameter of 12Y3 Mill. instead of 11, an altitude of S'/j, instead of 7 Mill. and is less 

 depressed in shape; only 2 s])ecimens have the bands quite hyaline, in the other ones a con- 

 spicuous brown peripheral band and a narrow subsutural one of the same colour, distinguish 

 them from a specimen formerly received of v. M.\rti:ns; as however these differences are more 

 gradual, as a few specimens are of the typical size, shape and colour of bands, and the 

 characteristic sculpture, con.sisting of strong ribs on the upper surface, with a nearly smooth base, 

 agree with v. Martexs' descriplion, there is, I think, no doubt that they belong to the same 

 species, which came from Dana, an island southwest-wards from Savu. 



Plectotropis v. Martcns. 



I. Plectotropis kangeatigcnsis n. sp. PI. XXXI, fig. 2. 



Stat. 16. Bay of Kankamaraan, South coast of Kangeang. 2 Spec. 



Shell vvidely umbilicated, carinated, conve.xly depressed, thin, fragile, opaque, white. 

 Whorls 4, rapidly increasing, slightly conve.x above, with a slight depression near the suture, 

 which is conspicuous, more so as the keel is prominent on penultimate whorl. Nucleus not con- 

 vex, nearly smooth, but under the lens with very fine wrinkles; on tiie second and subsequent 

 whorls, the sculpture consists of stronger, radial striae, nearly riblike in some paris, crossed by 

 fine, spiral striae; last whorl with a conspicuous, though not sharp, compressed keel, fainter 

 near the aperture, ba.sal part of last whorl much more convex than upper part, with the same 

 sculpture, though a little less coarse. Aperture oblique, angularly lunar, its upper and basal 

 margins conve.x, columellar margin nearly straight (damaged), joined with the basal one by an 

 obtuse angle; peristome rather thin above, slightly e.xpanded, thicker and narrowly expanded 

 near base. Umbilicus rather large, pervious, funnel-shaped, bordered by an obtuse angle.
