A large number of specimens of this species were collected by the 

 expedition, some of which are of great size. In the large males the 

 carapax is macttlated and streaked above with red and pale bluish ; 

 and the teeth of the antero-lateral margin have concave rather than 

 convex sides as represented in De Haan's figures. 



The females dredged near shore are not maculated, and have a 

 convex, strongly granulated carapax. 



This species was dredged on muddy bottoms in 6 to 12 fathoms in 

 the harbors of the Chinese coast, and was found in the markets of 

 Hongkong. It was also seen in calm weather floating or swimming 

 in the middle of the China Sea.
