Antennae black; head and thorax dark grey; abdomen 

 grey above, yellowish grey below. 



Expanse of wings 2 inches. 



Belongs to the group of A. panda, Godt., to the female of 

 which on the upperside it bears considerable resemblance. 



One specimen only. In Mr. Grose Smith's collection. 



XXVllI. — Bescrtptions 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 tlie mainland, and on Mount Moratau, Goodenough 

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

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

 only be given in one or two instances. 



1. Nanina amblytropis^. 



Testa orbicularis, subacute carinata, spira brevi convexe conoidea, 

 anguste perforata, supra fusca, baud nitida, subtus pallidior, 

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

 convexiusculi, inferue ad suturam impressi, submarginati, lineis 

 iucremeuti obliquis arcuatis, prope suturara subplicatis, striisque 

 inicroscopicis radiantibus et minute rugulosis sculpti, ultimus ad 

 peripberiam acute angulatus, subtus nitens, baud microscopice 

 striatus, lineis incremcuti mode sculptus ; apertura obliqua, angu- 

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

 margine columellari leviter incrassato, superne expanso, 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. Tiie sculpture consists, besides tiie lines 

 of growth, of exceedingly fine wrinkly stria? in the same 

 direction. It is this minute striation which produces the dull 

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

 is highly glossy.
