 0.48 ; breadth, 0.90 inch. 



These specimens were found at Cape St. Lucas by John 

 Xantus, Esq. 



Actaea I>ovii, nov. sp. 



Yery closely allied to the A¥est Lidian species A. setigera, 

 l)ut differing in the granulation of the carapax, which is finer 

 and more dense, and on the posterior regions more distinct. 



Dimensions of a male: Length of carapax, 0.45; breadth, 

 0.G3 inch. 



Found at San Salvador by Capt. J. M. Dow, and at Panama, 

 by Alex. Agassiz, Esq, 



Actaea eros^a. 



Actaea O'osa Stimpson, Notes on N. American Crust., p. 5. 



The raised parts of the surface of the carapax, between the 

 small cavities, are conical or ridge-like, and roughened. The 

 lobes of the antero-lateral mai-gin are not distinctly defined, 

 with the exception of the posterior one, which is small, trian- 

 gular, and projecting. 



This species differs from the Xantho vermiculatd of H. Milne-
