The accompanying revised description and figures are taken 

 from the type, a male, in the Australian Museum. 



Fig. 1.— Profile. 



Fig. 3.— Cheliped. 



Fig. 2. — Buccal frame. 



Carapace armed with long spines, the width slightly more than 

 ^ the length. Regions well defined, very convex, and limited by 

 broad shallow depressions. Hooked setae arise from minute 

 prominences on the body and ambulatory limbs. Rostral cornua 

 long and slender, tapering, somewhat incurved towards their 

 extremities, which are blunt and rounded; their upper edges are 

 carinate, and extend backwards to the gastric region, forming 

 a deep hollow on the frontal region. 



Carapace with ten knobbed spines, two on the mid-line of the 

 gastric region, inclining towards their bases; two on the cardiac 

 region, placed transversely with their bases almost united; two 

 on the intestinal region, the last being on the posterior border; 

 two others are placed obliquely on each branchial region, the 

 hinder almost on the same level as the cardiac pair, and directed 

 upwards and backwards, while the anterior is almost at right 

 angles to the length. 



Orbital region prominent, terminating in three slender spines 

 directed outwards and forwards, the middle one a little nearer 

 the first than to the third and curved slightly upwards. 

 Following these are two depressed postorbijtal spines, the first 

 acute and the second larger and obliquely truncate. Hepatic 

 region with a sub-bitid lobe. Inferior surface with several small 

 tubercles. 



Basal joint of external antenme with a short tooth at the 

 proximal end of its outer border, with a very prominent
