The Aniphipoda of Bermuda. 33 



broad and broader distally than wrist, palm nearly transverse, provided 

 with setae on posterior and distal portion of anterior margins and 

 palm ; finger stout and curved. 



Second gnathopods with small rhomboidal epimeron which is 

 higher than long ; second joint rather long, extending well beyond 

 epimeron ; third joint short ; fourth joint rather long with posterior 

 margin convex and distal margin much longer than proximal ; wrist 

 rather short with posterior margin prolonged to form cuplike pro- 

 cess in which the posterior margin of the hand fits proximally ; 

 hand very large and strong, broader distally, posterior margin pro- 

 longed apically to form strong fingerlike process which tends to 

 make the hand chelate, palm transverse and bearing 3 strong rounded 

 processes near articulation with finger which is strong and not 

 greatl}' ciu^ved, except at apex where it closes past the fingerlike 

 process of the hand, and which is broadest at middle. 



In female, first gnathopods with quadrilateral epimeron having 

 posterior margin forming a small triangular process and with ventral 

 margin provided with setae and cilia ; second joint long and slender 

 with 5 fascicles of setae on posterior margin and numerous longer 

 setae on distal ^/s of anterior margin ; third joint slightly longer 

 than broad ; fourth somewhat longer than third with anterior margin 

 \:ery short and posterior margin long and provided near distal end 

 w-ith many very fine cilia and several stoiit setae ; wrist longer 

 than hand and as broad as hand, provided on posterior margin 

 with numerous short setae which form a close set mass, and also 

 with a few longer pectinate spines on posterior margin and nu- 

 merous fascicles of setae near margin ; hand subrectangular, less 

 than twice as long as broad with posterior margin provided with 

 many setae of different lengths, some of which are finely pectinate, 

 palm finely serrate and armed with short submarginal spines, an- 

 terior margin with 4 fascicles of setae ; finger of usual form having 

 2 curved spines on outer convex margin and with several short 

 slender ones on concave margin. 



Second gnathopods slightly stouter than first, with epimeron very 

 similar to that of first but slightly higher; fourth segment with 

 posterior margin prolonged to form a triangular process and provided 

 with a few long setae ; wrist quite similar to that of first gnatho- 

 pod but larger, posterior margin furnished with fascicles of slender 

 setae among which are a few finely pectinate ones ; wrist as long- 

 as hand which is subrectangular, palm oblique with rounded prom- 

 inence near articulation with finger, finely serrate, furnished also 

 with numerous submarginal setae and with 3 prehensile spines,
