base to the triangular obtuse tubercle situated obliquely above 

 and behind the eye ; the eyes are light yellowish-brown, small. 

 The antennal squama surpasses the antennular peduncle by 

 about i/3 of its length; it is unusually broad, scarcely more 

 than 5/2 times as long as broad ; its distal margin is rallier 

 long, a little oblique, the outer triangular denticle rather short. 

 Telson is somewhat less than 3 times as long as broad, consi- 

 derably narrowed in its distal half, which at its narrowest point

is yet slightly less than half as broad as the most proximal 

 part of telson; the latéral edges are furnished with a rather 

 low number of proportionately short spines, and between thèse 

 numerous quite minute denticles are observed ; the distal 

 incision is scarcely i/5 of the total length; each lobe terminâtes 

 in a rather long and strong spine, and inside this a couple of 

 shorter but conspicuous spines are observed. — Length of
