HELIX-EUHADRA. 107 



The brown band is situated a very little above the middle of the 

 body-whorl, and passing just above its suture, is visible on two or 

 three of the preceding volutions. The umbilicus is very deep and 

 penetrable to the apex of the shell, but rather narrow, occupying 

 about one-seventh of the smallest diameter. Peristome rather broad- 

 ly expanded and white, with the exception of the columellar and 

 basal margins, which are stained with a dirty pinkish color. Over 

 the umbilicus it is broadly expanded, reflexed and joined to the up- 

 per margin by a thin callosity. This species is quite distinct from 

 H. myomphala, Martens, and, although agreeing in the style of col- 

 oration, differs in form and the umbilicus. 



The single example in the British Museum was presented by Mr. 

 George Lewis. (Smith.) 



H. MYOMPHALA von Martens. PI 29, figs. 7, 8, 9. 



Shell dextral, umbilicus closed, depressed conoidal-globose, 

 obliquely striate, decussated by very subtle close spiral lines, buff, 

 with a single peripheral chestnut band, the umbilical region con- 

 colored ; whorls 6J, scarcely convex, slowly increasing, the upper 

 ones angulate at the periphery, the last rounded, a trifle deflexed in 

 front ; aperture a little oblique, obliquely-lunar, peristome expanded, 

 white, margins distant, connected by a scarcely visible callus, upper 

 and basal margins well arched, columellar margin reflexed and 

 adnate at the insertion. (Martens.') 



Alt. 32, greater diam. 43, lesser 38 mill. ; aperture, length 27, 

 breadth 22 mill.

In form and size this species is nearest to H. qucesita but is always 

 dextral, with closed umbilicus, more numerous and more slowly 

 widening whorls, and finer sculpture. The single band is narrower 

 than in H. qucesita or H. peliomphala. A young specimen with only 

 5 whorls shows a pronounced keel (while a qucesita of equal size has 

 a very blunt one) and a narrow but not closed umbilicus. (Mart.)
