Figure 22, d. 



The carapace of this species closely resembles that of C. mar- 

 ginatus, but the male is easilj^ distinguished by the form of the 

 male verges (see fig. 22, d). The female abdomen is narrower than 

 in the other species. The carapace is rather strongly granulated. 

 The five antero-marginal teeth, following the orbital, are all similar, 

 broad at base, with sharp acuminate tips, their two edges nearly 

 equal, and scarcely bent forward, granulated and hairy on the bases ; 

 the two succeeding teeth are still more acute and more squarrose ; the 

 last tooth is more than three times the length of the preceding. The 

 front has four lobes, the two inner much smaller than the others, 

 obtuse ; the outer ones prominent, subacute ; preorbital tooth about 

 equal in size and more acute. 



The length to breadth of the carapace varies from 1 :2.08 to 1 :2.26, 

 Our Bermuda specimen has the carapace 32™™ long ; 66™™ wide 

 (total) ; 53'"™ wide without spines. 



The only Bermuda specimen examined was a male collected long 

 ago by J. M. Jones (coll. Yale Mus.). Its range is from Florida to 

 Rio, Brazil. Pernambuco and Bahia, Brazil (Smith) ; Rio Janeiro 

 (Dana). Porto Rico (Rathbun).
