ON A COLLECTION OF 



LAND SHELLS FROM GEBI ISLAND, MOLUCCAS, 



WITH DESCRIPTIONS OF NEW SPECIES. 



Hv HI'GII FULTOX. 

 (Plate iv.) 



The species noted in this paper were collected by Mr. John Waterstradt 

 on the island of Gebi, which is situated about midway between ^^'aigiou and 

 Halmahera Islands. 



1.— Xesta auliea, viv. 

 2.— Planispira kurri, I'lr. 



Numerous varieties occur of this species and the variation in size is re- 

 markable ; the followini; are the dimensions of two extreme forms : — 



A. Maj. diam. (including peristome) 21 ; alt. 10 millim. 



B. ,, ,, ,, 30; „ 13 ,, 



3.— Papuina unicolor, Viv. 



Heli.c unico/or, Pfr. : Proc. Zoo). Soc , 1845, p. 64. 



Ampelita unicolor, Pils.: Tryon's Man. Moll., vol. vi, p. 37, pi. 5, 

 figs. 74 — 76. 



An interesting discovery, as the habitat of this species was hitherto un- 

 known, and owing to its similarity in form to some species oi Aiiipelita, it had 

 been thought by some to be from Madagascar. 



4 —Papuina fallax, n. sp. 



PI. iv, figs. 6, 7. 



Shell somewhat depressed, narrowly perforate, rather thin, apex dark brown, 

 following whorls yellowish-brown, the last being darker in colour and sub- 

 angulate at the periphery which is ornamented by a very narrow dark brown 

 spiral band ; umbilicus encircled by a yellowish patch ; suture well defined 

 by a whitish line; who? Is 5, moderately convex, slowly increasing, last de- 

 cending ; aperture sub-oval, grey within; peristome moderately expanded, 

 slightly reflected, dilated at point of insertion, almost covering the umbilicus. 



Maj. diam. 27 ; alt. 19 millim. 



This species has a remarkable resemblance both in form and colouration 

 to the Cuban Cejjolis (Coryda) alauda, v. nirohiluff, Fer. Quite distinct from 

 any other species of Papuina known to me, the nearest being P. labium, with 

 which, however, it cannot be confused.
