40 List of the Japanese Species of Fenella. 
long and narrow, truncate in front, with parallel sides, pomted 
behind, and entirely of a white colour. It swims at the surface 
of the water, shell downwards, with great facility, and, in 
crawling, uses the muzzle to assist the foot. 
The nearest allied genus to Fenella is Alvania of Risso, which 
comprises some small Rissoid shells with cancellated whorls and 
a marginal varix to the outer lip. The genera Bittium, Leach, 
and Cerithiopsis, Forbes & Hanley, also resemble Fenedla in the 
turreted form of the shell; but in both those groups the aper- 
ture is emarginate in front. The genus is dedicated to one of 
Sir Walter Scott’s heroines (vide ‘ Peveril of the Peak’).
