GO^GBYLIA—DITHYRA. 14. 47 



Tab. nost. 4, fig. 6. 

 Mus. nost. The interior of rocks in Torbay. 



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

 rough, striate transversely, slightly angular and truncate at the an- 

 terior end , and rather abruptly truncate at the other: teeth project- 

 ing a little inwards, but running obliquely, by which it is distin- 

 guished from all the varieties of Anatina distorta : the front mar- 

 gin forming nearly a straight line. 



** Dentibus horizontalitir protensis. 4-7 

 With the teeth projecting horizontally inwards. 



Anatina testa depressd ovato-oblongd, latere antico angulato truncato declms. 



hiante, dentibus ovato-protensis. 

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

 rior end, with the teeth oval and projecting. 

 Mya declivis. Montagu, Test. Brit. tab. 1, fig. 2. 



Wood, Conch, p 93, tab. 18, fig. 3. 

 Turton, 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 prse tenuis. " This shell is not trun- 

 cated."
