 the latter of which is provided with numerous fascicles of setae ; 

 hand long and slender, almost rectangular, about twice as long as 

 broad and not broader than wrist, anterior margin slightly convex, 

 posterior margin with many setae, palm very short and irregular; 

 finger long and of usual form with concave margin provided with

Second gnathopods with epimeron slightly higher than long and 

 rounded with moderate notch in ventral margin dividing it into a 

 larger anterior and smaller posterior lobe ; second, third, and fourth 

 joints essentially as in first gnathopod ; wrist triangular, about as 

 broad as long with postero-ventral angle rounded and provided 

 with a tuft of setae ; hand strong, subrectangular, with anterior 

 margin slightly convex and provided with numerous fascicles of 

 setae, posterior margin also with numerous fascicles of setae, palm 

 oblique and convex, prehensile angle very prominent and acute ; 

 finger stout and curved with a few serrations on concave margin 

 fitting behind prehensile angle. 



Epimera of second gnathopod and first and second pereiopods
