 Monogr. vii. p. 380. 



(11) GROUP OF H. MOSELEYI. 



Imperforate ; the spire low, obtuse ; whorls few (about 4), rapidly 

 widening, the last descending in front ; surface obliquely corrugated ; 

 lip well-expanded. 



Allied to the group of H. motacilla, but imperforate and having 

 fewer whorls. 



H. MOSELEYI Smith. PI. 6, figs. 17, 18. 



Imperforate, depressed, the spire low, apex very obtuse ; whorls 

 3?-4, the earlier whorls very wide, the last whorl descending in 

 front, rounded at the periphery. Surface closely, finely sculptured 

 with forward-descending wrinkles, and lightly obliquely striated. 

 Earlier 1J whorls glossy, corneous, the remainder of the shell opaque 

 whitish, except a corneous, translucent tract around the umbilical 

 region ; banded with from one to five translucent-brown bands, or 

 bandless. 



Aperture rounded-oval, oblique ; peristome white, well expanded 

 all around, the face of the columella flat. 



Alt. 14, greater diam. 21, lesser 17J mill. (Specimen.) 

 Alt. 11 , greater diam. 18, lesser 15 mill. (Specimen.) 

 Alt. 15, greater diam. 23, lesser 19 mill. (Smith.) 



Wild Island, Admiralty Group. 



H. moseleyi E. A. SMITH, Proc. Zool. Soc. Lond. 1884, p. 263, t. 

 22, f. 2, 2a. 



The whorls are fewer and wider than in any other Papuina. 

 This, in combination with the obliquely corrugated surface, imper- 

 forate axis and depressed form, render it easy to recognize. 



It has been suggested that H. moseleyi belongs to Cristigibba, but 

 there is nothing about the shell to warrant such reference. 



H. NOV^GEORGIENSIS Cox. 



This species was included in Planispira in Vol. VI of the MANUAL, 

 p. 290, although I there expressed the opinion that it might be a 

 Papuina (Geotrochus'). I have now no doubt that it groups here, 

 being the nearest ally known of the preceding species.
