 One fine specimen; male. Trawled. Length, 84 mm. 



When the animal is fully extended the carapace is about one-fourth the length of the 

 animal, measured from the orbital margin to the extremity of the telson. The postero- 

 lateral margins of the carapace pass under the coxal plates of the first somite of the 

 pleon. A small carina traverses the dorsal surface from the cardiac region forwards, and 

 is lost in the serrature of the rostrum. The rostrum projects forwards to a length that 

 is subequal with the carapace, and is armed on the upper surface with ten small teeth that 

 are closer together near the frontal region and more distant anteriorly ; the under surface 

 is armed with five teeth that coincide with the same number, tooth for tooth, on the 

 upper surface, except the most anterior on the upper surface, which has no corresponding 

 tooth on the lower. The outer canthus of the orbit is clearly defined by a rounded 

 angle, and the first antennal tooth is small, and lies closely impacted between the bases
