DESCRIPTION OF AMPHIPEPLEA PETTERDI, 

 NEW SPECIES FROM NEW GUINEA. 



[Read before the Conchological Society of Great Britain and Ireland, July 31st, 1879.] 



By WILLIAM NELSON, 



President of the Society. 



This fine shell was found by Mr. W. F. Petterd during his 

 exploration of New Guinea, at Port Moresby, and I have great 

 pleasure in associating the name of the discoverer with the species. 

 It is allied in form to L. Strangei Ad. and Angas, from Australia. 



Shell ovately subglobose, light horn color, thin; spire short; 

 penultimate whorl expanded laterally to the right, giving to the 

 apical whorls, which are minute and pointed, an appearance of 

 being placed toward the left side ; whorls 5, last whorl large, 

 oblong; aperture large, auriform; outer lip sinuous, anteriorly 

 rounded, slightly reflected near its junction with the columella; 

 columella twisted; inner lip thin; suture deep; stri» oblique, close 

 and irregular. 



Length 25 mill., breadth 17 mill. 



Aperture 17 mill., breadth 12 mill. 



Habitat — Port Moresby, New Guinea. 



ACHATINA ACICULA Mull, in the ISLE OF WIGHT. 

 By C. ASHFORD. 

 In the excellent list of land and freshwater shells of this 

 island drawn up by Messrs. Guyon, Hambrough and More for 

 the Zoological Section of 'Venables' Guide,' our little Achat uia 

 does not occur. Within the last few days I have found it, though 

 not alive, on the crest of an old chalk pit on the northern slope of 

 Afton Down, near Freshwater. It occurs where the rapid descent 

 of the hillside is broken into tiny cliffs six to ten inches high, 

 exposing the soil down to the chalk. I see in my notes that I 

 took this shell, July 1872, in a similar locality on the Chalk Downs, 

 two miles south of Petersfield, Hants.
