SPIDER CRABS. BATHBUN. 17 



it...' Surface covered with a close pubescence. Of 

 the opines on the carapace the longest is one pointing obliquely 

 upward at the widest part of the carapace, on each side. 

 Nearly as long is the suberect cardiac spine in the same line ; 

 while the median spine directed slightly backward just above 

 the posterior margin is shorter and slenderer ; the marginal 

 hepatic spine is similar and points outward. Tubercles are 

 few : Three in a triangle on the after half of the gastric region, 

 the median one slightly behind the lateral pair ; three in a 

 group at the inner angle of each branchial region ; one 

 further back, on each side, in a line just behind the line 

 of long spines. Besides there are a few small granules, 

 especially toward the lateral margins. 



Rostrum longer than wide, divided more than half its 

 length ; horns flat, directed forward, spine-tipped. Pre- 

 orbital spines slender, directed upward, outward, and forward ; 

 postorbital lobes, viewed laterally, oval, flattened. 



Basal antennal joint longitudinally grooved through the 

 middle, a small tooth at distal outer angle. Angle of buccal 

 cavity produced in a thin lamina. 



Cheliped of female weak ; merus with a sharp upper 

 margin ; wrist with an outer ridge ; fingers about as long as 

 palm. Leg of moderate length, both pubescent and long- 

 hairy. 



The mature abdomen is longer than wide and covers the 

 sternum. Kggs few (twenty are visible when the abdomen 

 is laid back) and large (about .7 in diameter). 



Relationship. The species is related to D. expansa (A. 

 Milne Edwards). =D. orientalis, Miers. 19 Both are little orna- 

 mented Miid have only two lateral spines on each side, one 

 hepatic, one branchial ; but D. expansa has no median spines, 

 but numerous scattered tubercles, and its rostral horns are 

 short. 



Re/mark. This is the first Doclea noted in Australian waters 

 or at any great depth, the latter fact one to which the specific 

 narm- calif* attention.
