BUCCINOPSIS. 195 



B. VINOSUM, Lam. Australia; B. ZEBRA and B. TENUIPLICATUM, 

 Lam. Hob. unknown. These are not figured and M. Deshayes 

 has failed to recognize them. B. zebra may belong to the 

 Cerithiadse. 



B. SECHELLARUM, Dufo. Seychelles Isles. 



B. CHILOENSE, Phil. Chili. 



B. CASANI, Maravigna. . Hob*? 



B. ANTARCTICUM, Phil. ( ? = Columbella). Magellan's Straits. 



B. ACTONIS, Phil. Magellan's Straits. 



B. SULCATUM, Priele. PL 87, tig. 62*7. 



I have a proof figure received in advance of its publication, 

 but no description of this species. Locality probably Spitz- 

 bergen. 



B. NIVALE, Friele. PL 8*7, figs, 619, 620. 



Unpublished : by the author's kindness I am enabled to give 

 copies of the shell and peculiar operculum, taken from a proof 

 copy of a plate. It probably comes from the vicinity of Spitz- 

 bergen. 



<4enus BUCCINOPSIS, Jeffreys. 



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

 remarks that " the principal difference between this genus and 

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

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

 taking place by 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 

 very wide. According to Mr. Alder, 'its tongue (PL 2*7, 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.' "
