CARC(NOLOGICAL STUDIES. 51 



The dark browu colour of the fingers of Dana's species 

 extends for a short distance along the lower margin of 

 the hand ; this is not the case with the specimen of Carpil. 

 laevis whicli lies before me, but the specimen figured by 

 Milne Edwards (Nouvelles Archives du Muséum , T. IX , 

 PI. 5, fig. Sa) presents the same character. 



The breadth of the cephalothorax is 15^/, mm., its length 

 9 mm. These measurements are for Carpil. laevis respectively 

 iG'lg mm. and 10 mm. 



Heller (Novara-Reise) likewise records Carpil. tristis from 

 Tahiti , and according to Milne Edwards this species is 

 rather common on tlie shores of New Caledonia. 



2. Actaeodes Rich ter sii de Man. 



Actaeodes Richtersii, de Man, in: Zoologische Jahrbücher, heraus- 

 gegeben von J. W. Spengel , Abth. f. Systematik, Bd. IV, S. 412, 

 Taf. 9, fig. 2. 1888. 



An adult female and a very young male from Tahiti. 



Both specimens agree entirely with the original de- 

 scription founded upon an adult male, but the hands of 

 the female differ somewhat in form from those of the 

 male. The hands are namely somewhat shorter and more 

 slender ; they are a little more than three times as 

 long as high , whereas in the adult male the height of 

 the palm measures a little more than a third of the length. 

 As regards the proportion between the horizontal length 

 of the palm and that of the fingers, the female agrees 

 with the male, but the palm is distinctly more than once 

 and a half as long as high. The inner margins of both 

 fingers are entire and excavated for some distance at the 

 distal end; that entire, untoothed part of the margin is 

 slightly longer than half the length of the margin in the 

 immobile finger, slightly shorter than half the length of 

 the margin in the dactylus; as regards the number and 

 the form of the teeth , the female agrees with the male. 

 The hiatus between the fingers when closed is slightly 

 larger than in the male.
