62 SMITHSONIAN MISCELLANEOUS COLLECTIONS 



Expl. Exped., Crust., i, 233, but the carapax is flatter, the interan- 

 tennary front is narrower, and the eyes smaller- 

 Found at the Bonin Islands. 



Genus SPH^ROZIUS Stimpson 



This genus is separated from Pseiidozins Dana to include his 

 P. dispar and one other species. They are characterized by a globose 

 form, narrow carapax, and by the continuity of the frontal and 

 supraorbital margins, which are not separated by a notch, as in 

 most other genera of cancroids. The wide internal hiatus of the 

 orbit is filled by the outer antenna. 



85. SPH^ROZIUS NITIDUS Stimpson 



PtATE VII, Fig. 5, sa 



Sphccrozius niiidus Stimpson. Proc. Acad. Nat. Sci. Phila., x, p. 35 [32], 

 1858. 



Body small, subglobose ; carapax about four-fifths as long as 

 broad, convex, smooth and shining", not areolate, but with an in- 

 conspicuous longitudinal sulcus on the gastric region, reaching to 

 the front, which is emarginated and somewhat projecting at the 

 middle. Frontal margin continuous with upper margin of orbit. 

 Teeth of antero-lateral margin fotir in number, small but acute. 

 Chelopoda unequal, robust, rounded ; outer and upper surface of 

 hands granulous ; carpus smooth ; fingers nearly black and longi- 

 tudinally grooved on their outer sides. Ambulatory feet somewhat 

 hairy. 



Color in life : Carapax dark gray ; feet punctate with black. 

 Dimensions of a female specimen : Length of carapax, 0.235 '> 

 breadth, 0.29 inch. 



Allied to Psendozius dispar Dana, loc. cit., i. 235, pi. xiii, fig. 9, 

 but distinguished from it by its sharper antero-lateral teeth and by 

 the want of tubercles on the hands. 



Only one specimen of this species occurred to us ; this was found 

 in a cluster of Spoggodia which grew on a rock just below low-water 

 mark at the island of Hongkong, China. 



Genus HETEROPAXOPE Stimpson 



A well-marked group of cancroids is found in the eastern seas, 

 the species of which hitherto discovered have been referred to the 

 genus PanopCHS, to which they have much resemblance. This genus
