BARBADOS-ANTIGUA REPORTS 79 



UciDES coRDATus (Linnaeus) 



Rathbun, Bull. U. S. Nat. Mus., No. XCVII, 1918, p. 347, pis. 

 CX-CXIII, pi. CLIX, figs. 3 and 4, text-fig. 158. 



Barbados ; 1 6 small. 



Antigua ; mangrove swamp ; 2 large 6 . The larger has a 

 carapace 73.7 mm. long, 100 mm. wide. The greatest width com- 

 pared to the length is intermediate between that given in my 

 monograph for a smaller specimen of cordatus and the width of 

 occideritalis. 



This Antigua specimen lacks the first ambulatory leg on the 

 right side ; the first leg on the left side is shorter than the second 

 leg, but may not be normal. 



The smaller specimen of the two has the ambulatory legs of the 

 right side normal ; the first leg on the left side is no longer than, 

 indeed, a trifle shorter than the second leg. 



Both these specimens have the palm straighter below than in 

 the specimens previously described by me. In spite of these vari- 

 ations in cordatus, there is no likelihood of confusion with occi- 

 dentalis, as the palms of the latter are longer and slenderer than 

 any of the cordatus examined, and the carapace is narrower be- 

 hind in proportion to its greatest width.
