CG SVKES : DESCKll'TlOXS OF NEW LAND SHELLS. 



turc sub-triangular, witli tlic })eristoiue well expanded and retlexed, while, 

 the outer margin .sinuous, the basal margin slightly areheil. and the 

 columellar margin reflexed over the umbilical region, and iurnished with 

 a small tooth. 



Alt. 30 ; diam. max. So.o millim. 



Hab. — Waigiou. 



Nearly related to F. tnrris, II. Ad., but more depreSJ^ed, the ec^ne not 

 being so acute angled. 



Leptopoma diplochilus, n.sp. 



Sliell very similar in shape to a somewhat depressed form of L. rilreinii, 

 and densely, microscopically, spirally striated. Coloiu' i)ale lilac, with 

 narrow darker spiral lines (fourteen on the last whorl). Lip dotiblc, the 

 outer portion very largely expanded and flattened, with thin edges, sinuate 

 on the columellar margin ; the inner portion strongly projected forward, 

 slightly on the inner, but largely on the outer margin, where it projects 

 2.5 millim. 



Alt. l-i ; diam. max. 1.") millim. 



Hab. — Waigiou. 



This remarkable shell is unlike any other species of Leplupuma known 

 to me. owing to the presence of a double li]), with the '" inner tube " strongly 

 drawn out, and recalling some forms of Ci/rloiihorus. 



Leptopoma (Leueoptyehiai lamellatum, n.sp. 



Shell moderately umbilicated. thin, pellucid, turbinate, white, either 

 plain or flecked with red, or white on the last whorl with red upper whorls, 

 or banded (in one specimen) with dark brown, protoconch moderately 

 sharp ; sculpture spiral lirae, on the last whorl there is one at the peri- 

 phery and five above : microscopic spiral striation is also present ; the last 

 half of the last whorl is marked by about twelve strong lamellae, stronger 

 than and cutting the spiral Hrae. Whorls 5^, moderately convex. xMouth 

 rounded, with the lip thickened and reflected, white, continuous. Oper- 

 culum thin, horny, multispiral. 



Alt. 1() ; diam. max. IG millim. 



Hab. — Waigiou. 



Closely related to L. acalare, Ad., but much larger and slightly more 

 depressed. Some specimens are larger than the actual type. 



Palaina ponsonbyi, n.^^p. 



Shell ovate-conic, rinuite, white, faintly tinted with yellow : protoconch 

 moderately blunt and smooth, the other whorls densely sculptured with 

 closely-set irregular lirae ; those on the last whorl being far more distant 

 than the others. Suture well impressed. Whorls 7, convex, the penulti- 

 mate the broadest, and the last whorl being compressed and slightly flat-
