FIGI-UK '^J. </. 



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

 ginatus,\m\. the malt- is easily distinguished liy (he form of the 

 male verges (see tig. L'L\ <!}. 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 t\vo edges nearly 

 equal, and scarcely bent forward, u'ranulated and hairy on the bas.-> ; 

 the two succeeding teeth are still more acute and more si|iiarrose ; 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 :2.0S to 1 :2.26, 

 Our Bermuda specimen has the carapace :3i> mm long ; 06 mm wide 

 (total) ; 53 mm 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).
