irregularly tuberculose above, smooth below ; smaller hand (the left one) spinulose 

 above, and sparsely granulose on the outer side ; fingers pale brownish. 



" Color a clear light brick-red. Beneath pale red ; sternum white. Fingers with 

 brown tips. Eyes straw-colored. Dimensions of a female; — length of carapax, 

 0.31 ; breadth, 0.4-3 inch. 



"The carapax of the specimen taken at Ousima is more swollen than that of the 

 others, and less hairy ; — there are a few tufts of long hairs, 4 or 6 to each tuft ; two 

 on the gastric region are most conspicuous. 



" De Haan's description of his P. minutus (Fauna Japonica, Crust, p. 50) applies 

 very well to our species ; but his figure (PI. III. f. 2) is by no means a good repre- 

 sentation of it. The body in that figure is smooth, the feet very slender and little 

 hairy. The postero-lateral margin is represented as convex, while it is rather con- 

 cave in our species. 



" Dredged in the Northern China Sea, from a shelly bottom in twenty fathoms. 

 Also found among dead corals taken from a sandy bottom in 30 fathoms off" the east 

 coast of Ousima. A single specimen, probably of this species, was taken at the 

 Bonin Islands." 



In 1896, the "Albatross" collected in Hakodate Bay, Japan, 11^ fathoms 

 (station 3656), a single male, 5.5 X 7.3 mm., which is referred here. The 

 lobes of the front are oblique, finely denticulate, and at their outer end there 

 is a small spine. The tubercles of the palms are arranged somewhat in rows 

 and are sharp — rather stout spines than tubercles. Wrists also spinous. The 

 ambulatory legs have a few spines on anterior margin of merus. 



The young Pilumnus from Male agrees in all respects with the male from 

 Hakodate Bay, as far as its size permits, except that the tubercles of the larger 

 palm extend a little lower down on its outer surface. 



I am not sure that this is the P. hirsutus of Alcock, described as having 

 frontal lobes shaped as in P. vespertilio.

Male, at anchorage, January 1 1 ; one mature female. In this specimen the 

 median sinus of the front is shallower and broader than the submedian.
