212 Mr. H. Fulton on supposed 



whorls of a semitransparent flesh-colour, tipped at the apex 

 with dark brown, last whorl obsoletelj keeled at the periphery ; 

 there is a narrow grejish-blue band just above the umbilical 

 area, which is continued spirally upon the parietal wall; lip 

 and columella pale purple, connected b j a thin reddish-brown 

 callus ; lip slightly expanded and reflected ; interior of aper- 

 ture white. 



Long. 32 millim., maj. diam. 15 millim. 



Type in British Mu-seum. 



Loc. South Flores Island {Everett) ; Sumba Island. 



Some specimens have an additional narrow spiral band just 

 below the periphery. This species is very closely allied to 

 my A. sumbaensis, but can easily be distinguished by its 

 different coloration.

Ohacina Underwoodi^ sp. n. (PI. VI. fig. 9.) 



Shell ovate-conic, moderately thin, dark reddish brown, 

 polished, almost smooth, growth-lines showing more distinctly 

 at and below the suture, which is very narrowly but distinctly 

 filleted; whorls 5^, slightly convex ; apex obtuse; aperture 

 ovate, a little less than half the length of the shell ; lip 

 simple, scarcely thickened; columella incurved, truncate. 



Long. 21 millim., maj. diam. 11 millim.

Loc. Asaha Centago, Costa Rica (C. F. Underwood). 



The nearest species to this is aurantiaca, Angas, but that 

 species is of a much more elongate form and lighter colour.

 (PI. VL figs. 4, 4 a, 4^.) 



Shell subcircular, light yellowish brown ; umbilicus wide, 

 funnel-shaped and sharply angled ; whorls 6^, slowly in- 

 creasing, suture bordered with a depressed and well-defined 

 narrow margin, obliquely striated by growth-lines above and 

 below, last whorl compressed at the margin and acutely 

 keeled ; aperture very oblique, lip slightly thickened. 



Maj. diam. 14 millim., height 4^ millim., width of umbili- 

 cus 5 millim.
