 presents little or no variation in color. Dimensions of the carapax 

 in a male : Length, 0.3 ; breadth, 0.383 inch. 



Found in considerable numbers on shelly bottoms, in 10 and 15 

 fathoms, among the islands on the coast of China near Hongkong.

This species is allied to H. dcntata, but may be distinguished by 

 its much broader carapax, the proportion of length to breadth in 

 which is i: 1.46. The principal lateral tooth is smaller but acute; 

 the tooth forming the angle of the orbit is more prominent, and the 

 second tooth almost obsolete. The ocular peduncles are longer. 

 Colors as in the preceding species. Dimensions of carapax in a 

 male : Length, 0.26 ; breadth, 0.38 inch. 



Taken in the harbor of Hongkong. '^

'The family Rhizopids, comi)rising two pages of Stinip-sou's "Prodronuis" 

 and Nos. 144 to 148, inclusive, of the species, is missing from the manuscript 

 of this report; also the illustrations of this family, as well as of other 

 Ocypodoidca. This gap existed in 1875, when the manuscript was examined 

 by Prof. Sidney I. Smith, and it is probable that the missing parts were 

 removed by Dr. Stimpson himself for further study and were destroyed in the 

 Chicago fin- in 1871.
