rest ; entire surface of carapace covered with very minute tubercles and fine, curved, scattered 

 seta?. Front Math two strong, divaricating spines, beset with curved setae ; upper margin of 

 orbits plane, with a single spine anteriorly, and a strong, angular spine directed forwards, 

 with a deep notch in front. Fore-legs smooth, as long as the postfrontal portion of the cara- 

 pace ; hindlegs covered with very minute, brown tubercles, and beset with thin scattered hairs.

 in partem anteriorem thoracis pertinentibus ; marginibus lateralibus postice integris, tribus obtusis 

 paululum eminentibus spinis ad partem anteriorem, quam ad partem thorax angustus subito fit.

 introrsum curvato et antice majore ; manibus brevibus rotundatis, atque curvatis, duobus parvis tuberculis 

 in superficie exteriore et superiore; digitis subgracilibus, subcylindricis lateraliter compressis, et longis, 

 crassis, raris setis obsitis ; unguibus in medio paululum hiantibus, introrsum curvatis et minutim

Hab. Mare Sinense. 



Carapace longer than wide, ovately trigonal, surface smooth, as if denuded, with scat- 

 tered tufts of brown, villose hairs, and finely granulose towards the hinder part ; a small, 

 slightly prominent tubercular spine in the centre of the ventricular prominence ; a small 

 prominent spine in the middle of each lateral or branchial region, situated towards the 

 posterior part, and three small tubercles arranged above this, in a linear series, extending 

 towards the fore part of the carapace ; lateral margins entire, posteriorly, with three obtuse, 

 slightly prominent spines towards the anterior part, at which situation the carapace becomes 

 suddenly contracted. 



Front with two strong, prominent, rather short, parallel spines, somewhat incurved 

 towards their apices, and covered with thick, strong, curved hairs. Orbit, anteriorly, entire, 

 deeply incised posteriorly, with a prominent, obtuse, angular tubercle behind the notch. 



Fore-legs smooth, small, slender, equal in size, covered with scattered, long, stout hairs ; 

 the third joint subcylindrical, curved inwards and enlarged anteriorly ; fourth joint short, 

 rounded, and curved with two small tubercles on the outer and upper surface ; fifth joint
