330 SNODGRASS AND HELLER 



Range. — James Island. 



This variety is known only from three specimens taken on James 

 Island by Baur and Adams. We have not seen specimens of it. 

 According to Rothschild and Hartert, who examined Baur and 

 Adams' specimens, it is subspecifically related to G. fortis dzibia, dif- 

 fering from the latter only in having a larger beak. It, then, possesses 

 the largest bill of the G. fortis series, approaching nearest to G. 

 strenua.

Range. — Culpepper Island. 



We did not procure any specimens of this form. The measure- 

 ments of the beak given by Rothschild and Hartert are included within 

 the dimensions of the bill of G. strenua. The adult male differs, 

 however, from that of G. conirostris^ G. strenua and G. magn/rostis, 

 according to the describers, in having the " feathers of the breast, ab- 

 domen and back slightly edged with olive " and in having the rump 

 conspicuously olive. " Bill compressed and rounded, as in G. coni- 

 rostris., but, unlike the other species of Geospiza., abruptly narrowed 

 three millimeters from the tip and elongated sharply to the point."

 adult females taken on Abingdon, Bindloe and Tower in June. Be- 

 sides the adults there are numerous young specimens from James, 

 Abingdon, Bindloe and Tower. 



The adult males are exactly the same in plumage as adult males of 

 G . ftdiginosa and G. fortis. The specimens are all moulting ex-
