spout, and the sliell suspended by a wooden liook over the fire. 

 Mr. Adams says tliat this rude vessel was adopted several times 

 for the convenience of his party, and nnswered its purpose 

 admirably. 



The s))ecies of Triton being" numerous, several attempts have 

 been made to separate them into generic or subgeneric groups ; 

 the most successful being the arrangement of Messrs. H. and A. 

 Adams. Two of these groups, however, Simindum and Gabestana, 

 are so closely related that I think Kobelt has very judiciously 

 united them. Priene is the connecting form approximating 

 Triton and Ranella ; whilst in the latter genus species of the 

 group Lampas recall Triton. 



A very excellent catalogue of the genus has been published by 

 Kobelt, the arrangement of which I mainly follow ; adding, how 

 ever, some additional species, making about one hundred and fifty 

 in all. Kobelt has monographed the genus in Klister's Conchylien 

 Cabinet and there are also monographies by Tleeve and Kiener 

 in their respective Iconographies,
