HELIX-PAPUINA. 



H. GUADALCANARENSIS Cox. PL 4, figs. 80, 81 ; pi. 16, figs. 23, 24. 



Im perforate, globose-turbinate, the spire conical, apex obtuse, 

 brownish-corneous ; whorls 5, somewhat convex, the earlier 2 or 2? 

 unicolored, corneous ; the last whorl distinctly and rather acutely 

 angled in front, the angle becoming indistinct on the latter part of 

 the whorl ; toward the aperture the whorl usually descends a trifle. 

 Surface lightly striatulate, shining. Color pale brown, having a 

 wide white girdle at the periphery, and (typically) numerous narrow 

 brown bands above, fewer below. Aperture very oblique, large, 

 more or less distinctly banded inside ; lip expanded, white ; colu- 

 mella spreading at its insertion. 



Alt. 22, greater diam. 23, lesser 20 mill.

The angular periphery, numerous narrow bands, and the dark 

 streak just behind the expansion of the white lip are characteristic 

 marks of this species. H. philomela Angas is evidently closely 

 allied. 



Variety (pi. 16, figs. 23, 24). A color-variety having narrow 

 bands at axis and suture and broad bands above and below the 

 peripheral white zone. Form typical. 



Alt. 22, greater diam. 21, lesser 18 mill. 



H. HARGREAVESI Angas. PI. 4, figs. 72, 73, 74. 



Imperforate, low-turbinate, spire conical, apex obtuse white; 

 whorls 5-5 A, slightly convex, the last rounded at the periphery, 

 abruptly descending in front, but not descending as far as the basal 

 band. Lightly marked by growth-lines, but smooth and polished. 

 White, the lips and columella bordered with deep chestnut-brown, 

 the base suffused with brown around the columella; and usually 

 there is in addition a broad brown girdle on the periphery, a nar- 

 row brown border above and below the suture, and a basal stripe. 

 There are some sparsely scattered, small, grayish dots, usually few 

 in number and inconspicuous. 



The aperture is very oblique, subrhombic, white and showing the 

 band inside. The upper lip is not at all expanded; basal lips 

 slightly expanded ; columellar lip suddenly dilated, spreading in a
