moved from Buccinum to Fusus. The operculum in this and the 

 last species is unguicular, and has a terminal nucleus. The apical 

 whorls of this shell closely resemble those of Fusus Berniciensis. 

 As the present specific name is manifestly inappropriate, I would 

 venture to suggest that it should be changed to Broderipi, as a slight 

 testimony to the memory of its late lamented discoverer. 



Fusus Berniciensis, iii. 421. Among the results of Mr. Barlee's 

 last dredgings in Zetland is a remarkably solid and evidently very 

 old, though recent shell, which I must provisionally assign to this 

 species. It is nearly four inches in length, and not quite an inch and 

 a half in breadth, being therefore of a more slender form than F. 

 Berniciensis. But the peculiarity of this specimen consists in the 

 apical whorls not being blunt and symmetrical, as in F. Berniciensis, 

 but pointed aud mammillary, as in F. Islandicus. The outer lip is 

 of equal thickness with the rest of the shell, and is strongly ribbed 

 on the inside near the mouth. I at first suspected that'the difference 

 in the form of the apical whorls might be sexual, and that the same 

 relation might subsist between this variety and F. Berniciensis as 

 between F. Islandicus and F. propinquus ; but I have since ascer- 

 tained that male and female individuals of F. antiquus do not exhibit 

 any variation in this respect. 



F. Norvegicus, iii. 428. Mr. Barlee procured a very young speci- 

 men of this shell in his last Shetland dredgings. 



Trophon clathratus, iii. 436, var. alba. With the last {Mr. 

 Barlee). 



T. Barvicensis, iii. 442. Not uncommon on the north-eastern 

 coast of Ireland. 



Triton cutaceus, iii. 446 ; Sow. III. Ind. pi. 18. f. 1. Dr. Lukis 

 informs me that a full-grown and perfect specimen was taken alive 

 in February last (1859) by Mr. John Rougier from a large flat stone 

 in the south-west of the island of Lihou, while he was engaged in 

 gathering ormers (Haliotis tuberculata) at the extreme verge of the 

 lowest spring tide. It is now in the public museum at Guernsey. 



Mangelia Trevelliana, iii. 452. In dredged sand from Belfast 

 Bay ; very rare. 



M. rufa, var. Ulideana, iii. 457. Mr. Norman says he has lately 

 taken, in St. Catherine's Bay, Jersey, a magnificent and living speci- 

 men of this pretty variety with the typical form. I have also found 

 it at Tenby. It may be a distinct species. 



M. teres, iii. 462, var. alba. West of Ireland and Scotland (Mr. 

 Barlee). 



M. Leufroyi, iii. 468. In dredged sand from Belfast Bay (J. G. J.); 

 var. pallida. Zetland (Mr. Barlee).

 Bay, Jersey (Rev. A. M. Norman). 



Gasteropoda Opisthobranchiata.

 Scaphander lignarius, iii. 536, var. alba. West of Ireland and
