very coarse granulations, some resembling tubercles, scattered 

 chiefly on the outer branchial areas. This series of specimens 

 shows the females to have the carapace slightly longer in ratio 

 to the width, hence appearing more compact than do the males, 

 which have the carapace a slenderer oval, this slender appearance 

 being accentuated by the presence of much longer ambulatories 

 than are possessed by the females. 



All seven of the crabs bear several small barnacles each, these 

 being more frequently attached to the carapace, although occa- 

 sionally being found on the legs, or ventrad of the body. These 

 barnacles represent a very rare species in various stages of 

 growth, from specimens less than one millimeter long to some 

 seven millimeters long, of Poecilasma inaequilaterale Pilsbry. 



The carapaces of the seven crabs have the following dimen- 

 sions, all expressed in millimeters: 



Material examined: Seven specimens, two males and five 

 females, dredged from four to two and one-half miles off Fowey 

 Rocks, Florida (bearing 289° true to 273° true) , in depths ranging 

 from 200 to 100 fathoms, November 29, 1935.
