monia are the same shell: and upon recurring to the de¬ 
scription of each in Montagu, we can perceive no essential 
difference In his account of the V. Danmonia, he has con¬ 
trasted it with the V. Scotica only, having probably forgot¬ 
ten his previous description of V. srilcata, which appears to 
have been drawn up from a specimen out of Mr. Sowcrbyts 
cabinet. Montagu describes the V. sulcata as having con¬ 
centric ridges, the furro ws between which are broader than 
the elevated parts: Maton aud Rackett represent it as 
•smooth, with obsolete ‘wrinkles ; a character applicable to 
the V. eompressa of Montagu, our V. Montacuti $ their 
figure also represents a shell of a much more triangular form, 
with the beaks more elongated, than any of the numerous 
specimens which we have examined; arid being depicted 
with the margin quite plain, is a tolerably good figure of 
the V. Scotica. 
The present.specific name we have adopted, not only as 
being more characteristic and its primary denomination, but 
as the name Danmonia would lead to the opinion that it 
was peculiar to the coast of Devonshire.

- Shell roundish, rather flattened, covered with a pale yel¬ 
lowish-brown or olive-grCen skin, under which it is white* 
shaped and marked in every respect like the last, from 
which it can only be distinguished by the inside margin 
which is quite plain, and has a small rib or kind of rim round 
it close tb the edge. The specimens which we have col¬ 
lected on the coasts of Devonshire, are very little more than 
half the size of the V. sulcata of the same coast.
