The specimen is about one- third less than the " Challenger " 

 example from Bass' Strait, and differs considerably in the surface 

 sculpture. This, however, may be due to age. The cephalic 

 shield exhibits thirteen tubercles ; five form a transverse row 

 between the anterior margin of the eyes, and there are two 

 longitudinal submedian rows of four each, arranged in curved 

 lines, the first and last pairs being wider apart than those in the 

 centre. A median dentiform tubercle is present on the posterior 

 border of the shield ; in size it is equal to the largest of the 

 median processes of the peraeon. The mesial pleon tubercles 

 bear several smaller tubercles on each side. The epimeral pro- 

 cesses and the inner rami of the uropods carry three or four 

 small tubercles. The telson exhibits numerous flat, scale-like 

 bodies ; the central keel has six or more on each side, and there 

 is a very distinct series of about fourteen arranged transversely
