Most of tin* above fire from the collections of the North 

 Pacific (U.S.) Exploring Expedition: they have not been figured, 

 and the type specimens were destroyed in the great Chicago lire. 

 Some of them might be identified with other described species, 

 bnt it is better not to do so. I think, under the circu instances.

The following forty "species'' are described (but not figured) 

 by Mr. F. P. Marrat. who does not believe in species. I take 

 them, with great pleasure, at his own valuation, for I cannot 

 afford to expend iny time over diagnoses which should never 

 have been written by a gentleman holding such opinions as Mr. 

 Marrat does, as lo the instability of every specific character. 

 Theoretically. Mr. MarratJ relegates all the Nassae to one specific 

 form; practically, he describes such individuals of that form as 

 he likes to name; and if every other collector should adopt his 

 views and be equally industrious, we should eventually have 

 every individual specimen of the genus bearing a distinct specific 

 name: moreover each collector would possess the sole specimens 

 of his own species. Xo locality is given with most of the 

 descriptions.
