considered to be P. nanus, and if this proves to be correct, 1 would pro- 

 pose for the Chatham Island bird the provisional name of Pyrocephalus 

 minimus. 



28. Myiarchus magnirostris (Gray). 



Chatbam Island, two specimens; James Island, five specimens; In- 

 defatigable Island, one specimen; Abingdon Island, two specimens; 

 Duncan Island, four specimens ; Hood Island, two specimens ; Charles 

 Island, four specimens. 



There are apparently some differences between specimens from differ- 

 ent islands, but most of the skius being in poor plumage, I am not able 

 to make a satisfactory comparison. The single adult from Abingdon 

 Island, for example, has scarcely a trace of rufous on the inner webs 

 of the tail feathers (very decided in all the others), the inner webs of 

 these teathers being pale broccoli-brown, becoming dark hair-brown 

 next the shaft. 



Family CUCULID^E. 



29. Coccyzus melanocoryphus Vieill. 



Chatham Island, one specimen; Charles Island, one specimen. 



These specimens, both adults, I am unable to distinguish from main- 

 land examples, though that from Charles Island has the bill considera- 

 bly deeper, and broader at the base, than any I have seen. 



Family BUTEONID^. 



30. Buteo galapagoensis (Gould). 



Indefatigable Island, two specimens ; Abingdon Island, one specimen. 



This bird is so closely related to B. swainsoni that there can be little 

 doubt that it is merely a local form of that species, slightly differen- 

 tiated by long isolation from the parent stock. It differs chiefly, if not 

 entirely, in its heavier bill and feet. 



Family PELECANID^. 



31. Pelecanus californicus Ridgw. 



Pelecanus fuscus Sundev. P. Z. S., 1871, 125. — Salv. Trans. Zool. Soc. Lond., 



ix, pt. IX, 1876, 496. 

 Pelecanus californicus Ridgw. Water B. N. Ain., n, Aug., 1884, 143. 



Chatham Island, two specimens; also one specimen without label. 



The single adult example (No. 115961) is in the white-necked or post- 

 nuptial plumage, and agrees exactly with Californian specimens, except 

 that the lower parts are darker and more distinctly streaked with white, 

 each feather having a very distinct though narrow mesial streak of this 

 color. The pouch, in the dried skin, is light brown basally, and the bill 

 is chiefly orange-reddish, the sides of the under mandible with only a 

 slight blackish mottling toward the base.
