Uenus BUCCINOPSIS, Jeffrey?. 



Mr. Jeffreys, who places his genus in the family Muricida*, 

 remarks that " the principal difference between tins genus and 

 Buccinum consists in the operculum, the nucleus of which, is in 

 Buccinopsis terminal, at the inner base of the mouth, the increase 

 taking place b}- semielliptical layers ; while in the other genus it 

 is placed within the edge, at the outer side of the mouth, the 

 increase taking place by concentric layers. The egg-cases of 

 Buccinopsis are separate,* and shaped like a well-filled leather 

 purse, the opening for the egress of the fry being at the top and 

 verj' wide. According to Mr. Alder, 'its tongue (PI. 27, fig. 32) 

 differs from that of Buccinum undatum^ as well as from those of 

 the allied species of the genus Fusus, and makes a slight 

 approach to that of Mangelia. It has a single plain and slightly 

 curved tooth on each side, and a very thin, non-denticulated plate 

 in the centre.'"
