196 CRUSTACEA. 



Plate 11, fig. 1, female, enlarged four diameters. 

 Cape Verdes? Atlantic Ocean. 



Length of carapax, three and one-fourth lines ; breadth, five lines ; 

 ratio of length to" breadth, 1 : 1-5. The male specimen in the collec- 

 tions has the surface smooth, while in the two females the lens dis- 

 closes a fine granulation over the anterior part of the surface. The 

 channeling is neat and distinct ; moreover, in the female the arm and 

 hand above are areolate, rugose and granulous, and in the male only 

 corrugate. The antero-lateral margin is thin. Behind the posterior 

 tooth, the margin is arcuate but entire. The abdomen of the female 

 is obtuse at extremity, or very slightly emarginate; that of the male 

 is narrow, as in A. tomento&us. 



It is possible that the male specimen belongs to a distinct species ; 

 yet the character of the antero-lateral margin, and the general pro- 

 portions of the body and also of the hands, are the same in the two.
