 a rocky island near Port Stephens. 



On two new species of Crabs, of the genus Stenorhtnchus. 

 By William A. Haswell, M.A., B. Sc. 



The genus Stenorhynchus of Latreille was for a long time 

 regarded as being restricted in its range to European seas. 

 More recently, however, two species have been described from 

 the southern hemisphere — one, S. falcifer, by Stimpson from the 

 Cape of Good Hope, and the other 8. curvirostris, by Dr. A. Milne- 

 Edwards* from Bass's Straits. 



1. — Stenorhynchus brevirostris, sp. nov. 



Gastric region of the carapace with five tubercles, of which 

 four are situated anteriorly in a transverse line and very small, 

 while the fifth is much larger and situated in the middle line 

 close to the posterior border of the region. Cardiac region with 

 three tubercles, the two anterior being close together in the same 

 transverse line, and very large ; the third small, situated close 

 behind them. Two obscure tubercles on the lateral hepatic regions, 

 and three on the branchial. Lateral margins with two prominent 

 triangular teeth. Rostrum short, of two bluntish teeth which do 

 not reach further forward than the distal extremity of the second 

 joint of the external antennae, the furrow between them not 

 extending so far back as the line joining the posterior borders of 

 the orbits. No infra-orbital spine ; upper boundary of the orbit 

 very prominent, but without a supra^-orbital spine. Eyes with a 

 slight tuberosity on the anterior surface of their peduncle, and a 

 small conical projection on the anterior and superior aspect of 

 their distal extremity. Antennae and maxillipedes very similar to 

 those of S. phalangium. Epistome with a slight tubercle on each 

 side near the auditory organ. Anterior limbs equalling in length 

 about two-and-a-half times the breadth of the carapace ; arm in
