Operculum paucispiral, corneous, externally with a thin layer of lime, that outer surface 

 is concave, whitish, dull ; interiorly it is yellowish, smooth and convex. 

 Alt. 6, lat. 5, apert. ait. about 3, lat. 2'/ 2 mill.

The nearest ally may be A. brunnea, which is however much larger, with about the 

 same number of whorls, and that species has no auricle at the columellar margin, as far as 

 I can see from the description. It resembles also A. tristis Tapp. Can., which is however 

 smaller and has no spiral sculpture; the auricle agrées. As I was not certain if this genus 

 belongs to the Realiïdac, I hâve left it amongst the family in which FISCHER has located this 

 group in his Manuel de Conchyliologie. 



2. Adelomorplia campanulata n. sp. PI. VI, ng. 1. 



Shell depressedly-turbinate, strong, with a rather short, conical spire, umbilicated, greyish, 

 but colour not easily recognizable, the shell being much eroded, though taken alive, it has a 

 corneous epidermis on a few spots; whorls probably about 5, (the top-whorl broken) moderately 

 convex, separated by a conspicuous but rather shallow suture, considerably descending near 

 the aperture, last whorl dilated and campanulate. Sculpture not conspicuous, perhaps by the 

 érosion, but partly faint growth-striae and spiral ones are visible, last whorl depressedly- 

 rounded, flattened above at its last part. Aperture rounded, but with an acute angle above ; 

 peristome thickened, enlarged, but not reflected, columellar margin thick, its base angular 

 and still more thickened, but scarcely auriculiferous, only slightly covering part of the mode- 

 rately wide umbilicus, margins connected, only touching the body-whorl at the upper angle. 

 Operculum paucispiral, externally much concave, with a rather thick layer of lime, its upper 

 corner, in a^cordance with the shape of aperture, with an açute angle. 



Alt. 9, lat. g 1 '.,, apert. ait. 5, lat. 4 mill. 



New Guinea, Hellwig Mountains, Oct. 13, 1909; from 1000 — 1360 m. 



This species seems to be sulïïciently characterized, it agrées in many respects with 

 A. novae-hiberniae Quoy and Gaimard f. i. in being campanulate, but not at ail in shape, its 

 strength is also remarkable.

Tapp. Canefri. Fauna Mal. New Guinea, p. 279. PL 10, fig. 22, 23. 



New Guinea. Lorentz River, Sept. 5 — 12, 1909; near Bivak Island, Mardi, 1910. 



Varying in colour-pattern, many spécimens are typical, other ones hâve a more reddish 

 tinge, some with regular bands, instead of blotches some bandless, often a supra-carinal brown 

 band is visible. 



Canefri has located this species amongst the Assiminiidae, but the large, pectinate 

 outer uncini and the lacking of basai denticles on the médian tooth of the radula, hâve 

 induced me to locate it near Adelomorplia.
