Our specimens agree much better with De Haan's figures than 

 with those of Mihie Edwards in the illustrations to the recent edition 

 of Cuvier's "Regiie Animal." In the }"oung female the abdon-.en is 

 scarcely wider than in the male. Tlie color in life is pale brick red 

 above, clouded with bluish ; below whitish. 



It is common on mud and shelly-mud in five to twelve fathoms, in 

 Hongkong Harbor ; also taken in twenty-five fathoms, sand, in the 

 China Sea, near latitude 23° N. 



250. MYRA AFFINIS' Bell 



Myra affiiiis Bei.l, Lin. Trans., xxi, 296. 



A young female specimen referable to this species is found among 

 our collections, in which, however, the surface is but little granu- 

 lated, as in M. fugo.v, to which it is very closely allied. But the 

 teeth at the posterior extremity of the carapax are obtuse, and the 

 middle one is short (perhaps worn). 



The specimen in life was of a dusky brick-red color above ; sides 

 and feet paler and variegated with white ; beneath white. 



It was dredged from a shelly bottom in twent}' fathoms, in Kago- 

 sima Bay, Japan.
