Five specimens of this species are in the collection of the 

 Bishop ?\lusenm. Four of these, two males and two females, 

 were taken b}- Alvin Scale at Tahiti in 190 1. the other, a male, 

 was obtained b}- j. W. Thompson from the Honolulu market 

 in 1917. rnfortunately the dactyli of this latter specimen have 

 been removed. 



All of these specimens are apparently t\pical, agreeing in 

 structural details with descriptions previously published. Of 

 those from Taliiti. the larg-est one. a female, has nine lateral 

 teeth on the dactxlus of the rajitorial 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 IMiers. 

 llrooks, iiigelow, and others, is very evident in these specimens, 

 the lateral teeth of the dactyli of the males being- long-er and 

 stouter than those of the females.
