118 " ENDEAVOUR " SCIENTIFIC RESULTS. 



Additional locality. Oyster Bay, Tasmania, 26 fathoms; 

 E.5187 ; one male, two females, two young. Without 

 locality; E.6492; four males, four females (one soft shell). 



Measurements. Male holotype, entire length of carapace 

 12, width, including spines, 16.5, fronto-orbital width 10.5, 

 width of front between antennal notches 5.5 mm. 



Description. Carapace very convex from front to back, 

 suboval, the front little advanced beyond curve of antero- 

 lateral margins, the latter nearly as long as the convex 

 postero-lateral margins, posterior margin between legs of 

 last pair arcuate. Posterior fourth or third of carapace 

 smooth and bare; remainder covered with a thin coating 

 of short, light-coloured hair, which does not disguise the 

 surface. Regions fairly well outlined ; gastro-cardiac 

 depression deep ; also the median furrow leading from the 

 mesogastric region to the front. Surface roughened by 

 two or three stout spinules on the hepatic region, by smaller 

 spinules opposite the last lateral tooth, by the granuliform 

 sockets of many of the surface hairs, and by fine, close 

 granulation on the post-lateral regions. 



Edge of front invisible in dorsal view, median lobes 

 deeply separated, oblique, extremities broadly rounded; 

 small outer lobe dentiform with a tuberculiform tip. 

 Supra-orbital border irregularly spinulose and granulose, 

 inner angle not accented, notches obscure; outer angle or 

 first antero-lateral tooth broad, tipped by a short, stout, 

 curved spine, behind which is a spinule, and under which 

 are several spinules -. a notch separates this tooth from the 

 suborbital margin, armed with four or five stout spinules, 

 and near the inner angle a broad tooth with bispinulose tip. 

 The second, third and fourth antero-lateral teeth are 

 similar to the first, but larger; the fourth has a narrower 

 base than the second and third, and the spinule on its 

 posterior slope may be absent, Submarginal regions 

 granulose and spinulose, subhepatic region with three or 

 more spinules, some of which are visible from above. 



Chelipeds of large male stout, unequal, but similar in 

 shape and ornamentation ; merus very high, armed above 

 with two large spine-pointed teeth, followed behind by 

 obscure granulation on margin and on outer surface ; wrist 

 and hand armed with stout, acute spines, which on the 

 palm become lower and more and more tuberculiform 

 toward the lower and distal margins until they altogether
