Carapax arcuate. Larger hand small, joints all smooth, fingers

 of the pahn either smooth or obsoletely granulate ; fingers dentic- 

 ulate, regularly arcuate. 



Island of Bourou ! Guerin's Collection (Phila. Academy); Mauritius 

 (Edw,, White); Zanzibar, Mozambique and Mascarenes (Hilgendorf ); 

 Java (Edw.), Ceylon and Madras (Heller); Neic Caledonia (A. M. 

 Edw.). 



I also understand that Maillard found this species at Reunion, 

 Injt I have not seen the work. 



Hilgendorf from an actual comparison of specimens says that 

 the perpJexus and chlorophthahnus of Edwards are the same. The 

 (r. stenodactylus of Lockington (Proc. California Acad., vii, p. 

 148, 1877), from West Coast of Lower California, would appear 

 from the description and a rough figure of the hand sent me by 

 the author to be near this species ; it certainly is not stenodactylus 

 of Edwards and Lucas.
