EXTRACT FROM AN UNIM'IiiJSHEl) liEI'OKT OF I)R. WILLIAM STLMPSON, 

 ON THE CRUSTACEA OF THE NORTH PACIFIC EXPLORING EXPEDITION, 

 1853 TO 1856.

Amoiij? a larj^c iiuiiib«'r of examines of this sptM-Jcs collected by the 

 expedition there are two adult males which differ so iiiiu;)! in t lie size and 

 character of the chelopoda from the specimens ordinarily found jmmI 

 those hitherto figured and described, that they mij^ht well be taken for 

 a distinct species. The carapax of one of these specimens is 1 inch long 

 and O.S,") inch broad. Proportion of breadth to length, 1 : 1.17. The 

 cheloi)oda are large and robust, 1.8 inches in length. Hands much 

 inflated ; tingers gaping posteriorly; movable one with a large tooth at 

 its iniu'rbase. 



In nine tenths of the male specimens taken, many of which are at least 

 two-thirds as large as that above described, the hands are slender and 

 weak, like those of the female; this (immature) form is that represented 

 by Guerin's figure. I n the sterile females, which occurred in equal num- 

 bers with the ordinary females and the males, the abdomen is flattened 

 and only two-thirds as wide as the sternum. 



In all of our specimens the pra'orbital tooth is very small ; the orbits 

 are interrupted above by two deej) fissures, and below by one wide fis- 

 sure divided into two by a small tooth. The projections of thecara[)a.\ 

 are rather tubercles than spines. In color, the body is light reddish 

 above, mottled with white; below, white; feet, whitish annulated with 

 red. The figiiie given by Milne Edwards in the "llegne Animal" is 

 less characteristic of our specimens than that of Gucrin. 



Dredged in the Harbor of Ilong Kong, China, on a muddy bottom, at 

 the depth of fathoms.
