' Twenty specimens. 

 " Twelve specimens. 

 Average measurements of specimens from different islands are as follows: 



Locality. 



MALES. 



Two adult males from New Providence. . . 

 Two adult males from Concepcion Island. 

 Two adult males from Eleuthera Island . . 

 Three adult males from Watlings Island.. 



Five adult males from Rum Cay 



Two adult males from Abaco 



Two adult males from Green Cay 



One adult male from Cat Island 



One adult male from Inagua 



FEMALES. 



Two adult females from New Providence . 

 One adult female from Concepcion Island 

 One adult female from Eleuthera Island. . 

 One adult female from Watlings Island. . . 



Two adult females from Rum Cay 



Three adult females from Abaco 



One adult female from Green Cay 



One adult female from Inagua 



In addition to these specimens with sex determined many unsexed examples have 

 been examined. Nevertheless, the different islands are much too inadequately repre- 

 sented to show conclusively whethei there are constant local differences or not. The 

 specimens from Highburna Key and New Providence seem to be lighter and duller 

 colored above than others, but to what extent this is due to difference of season I am 

 unable to determine.
