* Stimpson, from an examination of alcoholic specimens of Ericrate crenaius De 

 Haan, has shown (Boston Journal Nat Hist., vol. vii, p. 588, 1863) that DeHaan's 

 genus Eucrate ia distinct from the .E'Mcrafe as described by Dana, DeHaan's genus hav- 

 ing the male organs, or verges, arising i'vnn ihe coxas of the posterior legs, and there- 

 fore belonging to the Carcmop^aci'tice i if Edwards, while Dana's species has sternal 

 verges, and must therefore form the type of a new genus, for which I propose the 

 name Eucratopsis. The genus thus constituted appears to be nearest allied to 

 Speocarcinus Stimpson (Annals Lye. Nat. Hist., New York, vol vii, p. 59, 1859), 

 from which it is distinguished by the larger orbits, by the approximation of the inner 

 margin of the maxillipeds, and by the much greater narrowness of the posterior 

 part of the sternum.
