t In naming this genus, and some others mentioned in this paper, respecting which doubts may 

 be entertained, Mr. Sowerby appears to have been influenced by a desire to produce all the infor- 

 mation which the specimens could afford, conceiving that even if the names be erroneous the 

 figures may still have some value as objects of future comparison.
