rived from the carapax ; but the tubercles of the hands are 

 larger, and more crowded, projecting like scales, and ciliated 

 beneath. 



Found at Mazatlan by Capt. C. P. Stone. 



liUpa bellicosa {Sloat, MSS.), 



Agrees with L. hastata in almost every character, except 

 ^that the last two joints of the abdomen in the male are broader 

 and more flattened. 



Taken at Guaymas, in the Gulf of California, by Capt. C. P. 

 Stone. It is the first of the Portimidm discovered on our West- 

 ern coast. 



I^upa Crilibesii, nov. sp. 



This species is intermediate between L. sayl and Z. spini- 

 mana. In the characters of the antero-lateral margin, it 

 resembles L. sayl, the lateral spine being at least as long as the 

 space occupied by the four teeth in front of it. Frontal mar- 

 gin with four teeth nearly as prominent as in L. spinimana / — 

 the sub-median tooth is, however, more prominent than in that 

 species, thongh much less so than in Z. sayi. Surface of the 

 carapax granulated and pubescent. There are three or four 

 naked transverse ridges or raised lines, two of which arise at 

 the lateral spines. Chelipeds and abdomen of the male as in 

 Z. spinimana. Dimensions of carapax in the female ; — length, 

 1 ; breadth, spines included, 2"18 inch. 



Found on the coast of South Carolina, by Capt. Kurtz, and 

 at St. Augustine, Florida, by Mr. Dorman.
