NO. 2047. AMERICAN BRACHYRHYNCHOUS CBAB8—RATHBVN. 123 



32.5 mm. As 4 specimens from different localities in Mexico agree 

 in presenting certain characters which separate this form from the 

 African P. spectahilis de Man, it seems best to consider it as a distinct 

 species. 



The fourth tooth of the lateral margin is farther back than in 

 spectahilis and the postero-lateral margins behind this point are less 

 convergent and more nearly parallel. 



The margin of the front is more distinctly 4-lobed and the median 

 sinus is larger and more U-shaped. 



The dorsal surface of the carpus is not oblong but of nearly the 

 same length and width. 



The merus and carpus joints of the ambulatory legs are narrower 

 and their sides more nearly parallel.

SESARMA (SESARMA) VERLEYI, new species. 



Plate G. 



Type-locality. — Jamaica: Mulgi-ave (a small village in the Cockpit 

 country near Ipswich, St. EUzabeth); 1 female collected by Miss 

 Verley and received through Mr. P. W. Jarvis. 



Type.— C^i. No. 24940, U.S.N.M. 



Dimensions. — Female type, length of carapace 20 mm., width 

 22.8 mm., fronto-orbital width 16.5 mm., width of front 9.1 mm. 



Carapace strongly narrowed anteriorly, convex fore and aft, regions 

 and suprafrontal lobes fairly well marked ; of the latter the outer pair 

 are narrower than the inner pair and their anterior margin more 

 strongly marked. Anterior part of carapace granulated, postero- 

 lateral area finely striated. 



The lower margin of the front forms two prominent lobes in dorsal 

 view. The sides are oblique and the angles rounded off. 



Upper margin of orbit directed outward and forward, outer angle 

 broad and obtuse, the margin between it and the lateral tooth con- 

 vex. This tooth is subrect angular wdth thickened tip. 



Chelipeds of female narrow. Outer surface of arm and wrist 

 crossed by short lines of granules, upper and outer margins rough 

 wdth short oblique and parallel lines of granules, inner margin irregu- 

 larly spinulous. Palms longer than wide, sparingly covered with 

 depressed granules, more numerous above and toward the carpus, 

 where they are arranged somewhat in rows. Fingers as long as the 

 middle length of the palm, prehensile edges irregularly toothed except 

 the distal third, which has a straight horny edge, tips curved toward 

 each other. 



Legs unusually long; the third leg is three and one-fifth times as 

 long as the carapace, its merus is four times as long as wide. The
