CLIBANARIUS COOKI, new species. 



Allied to G. cubensis (Saussure) = C. sclopetariu^ Stimpson, not Herbst. 

 Eyes long and slender; second and third pairs of feet not striped. 



In most of its characters this species resembles C. cubensis of the 

 eastern coast of America. The anterior part of the carapace is i^ro- 

 portionally shorter than in that species. The eyes, 

 though longer and slenderer than in other West 

 African species, are shorter than in cubensis; they 

 reach slightly beyond the peduncles of the antennae 

 and aatennulge. Peduncles of antennulse very lit- 

 tle longer than those of the an- 

 tennae. Last segment of peduncle 

 of antennae more slender than in 

 cubensis. 



Chelipeds, as In cubensis, equal. 

 The penultimate segments of the 

 ambulatory legs are narrower 

 than in cubensis. These legs are 

 without stripes or bands of color; otherwise they re- 

 semble those of cubensis. The dactylus of the second 

 leg is about as long as its propodus and one third its 

 carpus; that of the third leg as long as its propodus 

 and two-thirds its carpus.

 ish red.
