the China Sea.

Five specimens of this species are in the collection of the 
Bishop Museum. Four of these, two males and two females, 
were taken by Alvin Seale at Tahiti in rg01, the other, a male, 
was obtained by J. W. Thompson from the Honolulu market 
in 1917. Unfortunately the dactyli of this latter specimen have 
been removed. 
All of these specimens are apparently typical, agreeing in 
structural details with descriptions previously published. Of 
those from Tahiti, the largest one, a female, has nine lateral 
teeth on the dactylus of the raptorial limb, including the terminal 
one, while each of the other specimens from that locality bears 
ten teeth on the dactylus. 
The matter of sexual dimorphism, mentioned by Miers, 
Brooks, Bigelow, and others, is very evident in these specimens, 
the lateral teeth of the dactyli of the males being longer and 
stouter than those of the females. 
3rooks describes and figures'® the accessory organs of the 
first abdominal appendage of the male of this species. In order 
to present in more complete detail the general features of this
