Rostrum rather short, not quite reaching to the end of the 

 antennary scale ; straight, sub-acute, armed above with six small 

 teeth ; unarmed below. No marked dosal carina, nor longitudinal 

 sulci on the carapace. Surface of carapace pilose ; gastro-hepatic 

 sulcus moderately dee}) ; hepatic and supra-orbital spines absent. 

 Eyes large. Elagella of antennules and antennae (wanting). 

 External maxillipedes hairy, palp extending to the distal end of 

 the second joint. Anterior pair of ambulatory limbs (wanting). 

 Third pair longer than second ; fourth shorter than third ; fifth 

 about equalling the latter in length. Under surfaces of second 

 and third pairs devoid of spines. Abdomen pilose ; a mesial dorsal 

 carina on the second, third, fourth, fifth and sixth segments ; no 

 spine in the middle of the posterior border of the sixth. A deep 

 lateral notch on the posterior border of the fourth and fifth 

 segments. Last abdominal segment with a narrow mesial groove ;

 carapace. Surface of carapace pilose ; gastro-hepatic sulcus 

 shallow ; orbital spine absent ; antennary and hepatic spines 

 present. Flagella of antennules very short, not much exceeding 

 in length the last segment of the peduncle. Palp of external 

 maxillipedes exceedingly short and slender. Proportionate 

 length of ambulatory limbs as in preceding species ; a spine on 

 the under surface of the second joint of the first and second pairs. 

 Abdomen with the second to the sixth segments carinated. Posterior
