Sulcus each side of the rostrum is rather narrow and deep 

 anteriorly, making an emargination of the edge. Eyes large and 

 very convex, rather close to the rostrum. Orbital lobes over the 

 eyes rounded in front. 



Antennules (pi. 32, fig. ic) with the basal segment short, stout; 

 second segment not twice as long as third ; basal spine short and 

 broad, bilobed, with a minute spine below ; upper one does not 

 reach beyond the end of first segment; inner flagellum thick for 

 twelve or more basal joints ; distal lash slender, with about eight 

 segments. 



Basal segments of antennae short, with a small, short, very 

 slender spine on the second. Antennal scale (pi. 32, fig. I, s} is 

 about as long as the peduncle, lanceolate, its spine longer than the 

 scale, very acute, its plumose hairs long and abundant ; flagellum 

 very long and slender, exceeding the entire body. 



Large chela hairy, elongated, not much compressed, tapering 

 distally, with a narrow notch and sharp tooth on the upper margin 

 distally, from which a submarginal groover runs back on each 

 side, that on the outer side larger and longer, reaching the proximal 

 fourth ; dorso-proximal area bounded by an impressed line ; 

 dactyl compressed, evenly arched, relatively short, articulated 

 somewhat obliquely, pale orange ; carpus subhemispherical, as long 

 as broad, with two slight distal teeth at the angles (text-cut 7) ; 

 merus with small triangular articular teeth. Smaller chela (pi. 32, 

 fig. i, /') is long, slender, very simple, with nearly straight margins 

 without notches or spines except a small dorsal tooth at the articu-

lation with the dactyl ; very hairy both on the palm and fingers ; 

 the hairs form a row of tufts above and below, and a larger tuft 

 at the tip of the fixed finger directed forward, and also a row in a 

 groove close to the cutting edge, in small tufts. The dactyl is long, 

 slender, evenly rounded, nearly straight to the distal third where
