Tab. most. 4, fig. 6. 

 Mus. nost. The interior of rocks in Torbay. 



Siiell half an inch long, and three quarters of an inch broad, 

 rough, striate transversely, slightly angular and truncate at the 

 anterior end, and rather abruptly truncate at the other: teeth 

 projecting a little inwards, but running obliquely, by which it is 

 distinguished from all the varieties of Anatina distorta : the front 

 margin forming nearly a straight line. 



^t^ Detitibus horixontaliter protensis. 4-7 

 With the teeth projecting horizontally inwards. 



Anatina testa depressa ovato-oblongu, latere antico angulato <leiiivis, 



ti'uncalo hianie, detitibus ovato-protensis. 

 Shell flattish, oval-oblong, angular truncate and open at the 



anterior end, with the teeth oval and projecting.

 Ttirton, Conch. Diet. p. 98. 

 Mus. nost. Dredged up in Torbay. 



Shell nearly an inch long, and an inch and a half broad, flat, 

 rough, and of a darker color at the truncated side. It very much 

 resembles the young of Anatina pubescens ; but is known by the 

 large oval projecting teeth, which extend forwards and have no 

 lateral attachment. 



Montagu has given a good figure of this shell, but his descrip- 

 tion is that of the Anatina praetenuis. " Tliis shell is not trun- 

 cated."
