136 THE CONDOR Vol. IX 



At San (Juintin, Brown made large collections, chiefly of sea birds, but these 

 we do not list as they contained species mostly well known from the region. 



In October and November he visited Rosario, latitude 30°; and in late Feb- 

 ruary, March and early April he worked south a little past latitude 29° or almost 

 opposite Cerros Island, collecting at Santana, Rosarito, San Andris and San Jabier. 

 It is the specimens secured at these points, south of San Quintin, that we list in 

 the present article. The region is an interesting one, not only because several 

 subspecies are peculiar to it, but because in other cases it appears to be where the 

 Cape St. lyUcas form intergrades with that of southern California or northern 

 lyower California. Some of the records also extend the ranges of Cape forms to 

 well up the peninsula, as in the case of the Violet-green Swallow and the Ash- 

 throated Flycatcher. 



A good deal has already been published on the birds of this general region by 

 Anthony, Bryant, Belding and others, but by far the most important contribution 

 to our knowledge of the ornis of lyower California is Wm. Brewster's "Birds of 

 the Cape Region of L,ower California."^ In this carefully executed work the 

 author gives the range of every species and subspecies so far as known, and refer- 

 ences to the writings of all other ornithologists who have dealt wdth lyower Cali- 

 fornia birds. 



Puffinus opisthomelas Coues. One male, San Jabier, April 2, 1907. 



Parabuteo unicinctus harrisi (Aud.). Two males, Rosarito and Santana, 

 March 3 and March 19. 



Accipiter cooperii mexicanus (Swains.). One male, Rosario, Nov. 4, 1906, and 

 one female, November 25. 



Accipiter velox pacificus (Lesson). One male, Rosario, November 19. 



Buteo lineatus elegans (Cassin). One adult female, November 9. 



Cerchneis sparveria peninsularis (Mearns). Four specimens, both sexes, 

 Rosario, November, and Santana, March 18. The latter, an adult male, is a pale 

 and small example, its wing measuring but 167, and is an extreme example of 

 ■peninsularis. 



Lophortyx californicus vallicola (Ridg. ) . Eighteen specimens, Rosario, October 

 and November, and San Jabier, San Andris and Rosarito, February and March. 

 Nests wdth eggs were taken at San Jabier, March 27 and April 1. 



Oxyechus vociferus vociferus (I^inn.). One female, Rosario, November 6. 



Zenaidura carolinensis carolinensis (I^inn.). Two specimens: a female, Rosario, 

 November 6, and a male, Santana, March 18. 



Melopelia leucoptera (Linn.). One adult female, Santana, March 20. 



Chamaepelia passerina pallescens Baird. One adult 'female, Santana, March 14. 



Geococcyx californianus (Less.). Three specimens, both sexes, Rosario, 

 October and November, and Santana, March. 



Colaptes chrysoides brunnescens Anthony. Eight specimens — one ^ from 

 Rosario, November 26; seven, both sexes, from Santana, San Jabier, and Rosarito, 

 March. 



These skins are a trifle darker brown on the upper parts than in specimens 

 from Arizona and Sonora in corresponding plumage, and, if brunnescens can be 

 maintained as a subspecies, would probably all be considered as belonging to it. 



Sphyrapicus ruber (Gmel.). One female, Rosario, November 2. 



Dendrocopus scalaris lucasanus (Xantus). Five adults, both sexes, Santana 

 and San Andris, February and March.
