AnteuiuB black ; head and thorax dark grey ; abdomen

XXVllI. — Descriptions of new Species of Land- Shells from 

 New Guinea. By Edgar A. Smith. 



The species about to be described were collected by Mr. 

 William E. Armit during an exploring expedition on the 

 north-east coast of British New Guinea, on Mount Maneau, 

 on the mainland, and on Mount Moratau, Goodenougli 

 Island ; also at the back of Cloudy Bay, on the south coast. 

 It is to be regretted tiiat the exact locality of the species can 

 only be given in one or two instances. 



1. Nanina amhlytropis'*'. 



Testa orbicularis, subacute carinata, spira brevi convexe conoidea, 

 auguste perforata, supra fusca, haud nitida, subtus pallidior, 

 corneo-lutescens, polita ; anfractus 6, lente crescentes, leviter 

 convexiusculi, inferne ad suturam impressi, submarginati, lineis 

 incremeuti obliquis arcuatis, prope suturam subplicatis, striisque 

 microscopicis radiantibus et minute rugiilosis sculpti, idtimus ad 

 peripheriam acute angulatus, subtus niteiis, haud microscopice 

 striatus, Kneis iucrementi mode sculptus ; apertura obliqua, angu- 

 latim sublunata, intus albida vel livido-alba ; peristoma tenue, 

 margine columellari leviter incrassato, superne expanse, foramen 

 umbilicale semiobtegente. 



Diam. maj. 23 millim., min. 20, alt. 13 ; apertura 7 alta, 11^ lata. 



I am inclined to think that this species does not exceed the 

 dimensions given above. The spire is convex and terminates 

 in an obtuse apex. The sculpture consists, besides the lines 

 of growth, of exceedingly tine wrinkly stride in the same 

 direction. It is this minute striation w^hich produces the dull 

 surface. Underneath, where they are not present, the shell 

 is highly glossy.

 Testa iV. Cainii t similis, sed spira minus conoidea, aafractibus
