Sept., 1907 CATALOG OF BIRDS COIvIvECTED IN MIDDLE LOWER CALIFORNIA 139 



Santana, March. These two skins are not typical, but are tending toward hyt>o- 

 leuca of the Cape region. 



Lanius ludovicianus gambeli Ridg. Eight adults, both sexes, Santana, Rosa- 

 rito and San Jabier, February 27 to March 30. These skins were identified for us 

 by Nelson and Oberholser, who pronounce them perfectly typical. Gambel's 

 Shrike appears to be the breeding form of the whole peninsula of I^ower California. 



Vireo vicinior Coues. One adult female, Santana, March 13. 



Vireo bellii pusillus (Coues). One adult male, Santana, March 17. 



Ampelis cedrorum (VieilL). Two males, Santana, March 14 and 20. 



Phainopepla nitens (Swains.). Three adults, both sexes, Santana, March. 



Tachycineta thalassina brachyptera Brewster. Three adult males, Santana, 

 March 11. These are extreme examples of the Cape St. I^ucas form, measuring 

 respectively— wing 107, 104, 103.5; tail 42.5, 42, 43. This record establishes the 

 fact that the form extends at least half way up the peninsula. 



Anthus pensilvanicus (Latham). One adult male, Santana, March 24. 



Helminthophila celata lutescens Ridg. Three specimens, two males and a 

 female, Santana and San Jabier, March 11 and March 28. 



Geothlypis trichas arizela Oberholser. Two adults, male and female, San 

 Jabier, March 28 and April 4. The plumage is quite abraded in both, and they 

 have the appearance of having been breeding birds. 



Wilsonia pusilla chryseola Ridg. Two adult males, Santana, March 19 and 20. 



Scolecopbagus cyanocephalus (Wagler). Three males, Rosario, November. 



Icterus cucullatus nelsoni Ridg. One adult male, Santana, March 2. 



Icterus parisorum Bonap. Three males, Santana, March 16 to 22. 



Agelaius tricolor (Aud.). One male, Rosario, November 11. 



Agelaius phoeniceus neutralis Ridg. Two males, Rosario, November. 



Sturnella neglecta Aud. Five specimens, both sexes, Rosario, November, and 

 Rosarito and San Jabier, February and March. 



Astragalinus psaltria hesperopbilus Oberholser. One adult female, San Jabier, 

 March 27. 



Carpodacus mexicanus frontalis Say. Two adults, male and female, Santana, 

 March 20 and 31. The adult male is in color perfectly X-ygixz-AS. frontalis, with the 

 red portions of the plumage restricted exactly as in the average male of that form. 

 Its wing measures 74 mm. — perhaps a trifle short iox frontalis; but Mr. Brewster 

 found so much variation in his series from Cape St. L^ucas of C. in. rnberrinuis in 

 measurements that he considers this character cannot be relied upon to distinguish 

 the form. The wing of the female measures 74 mm., also — about the average 

 length in any large series of C. vi. frontalis, female. 



Calamospiza melanocorys Stejneger. One male, Santana, March 31. 



Passerculus sandwichensis alaudinus (Bonap.). Two specimens, male and 

 female, Rosarito, February 25. 



Amphispiza bilineata deserticola Ridg. Fourteen adults, both sexes, Rosarito, 

 San Jabier, Santana, February 26 to April 1. 



Amphispiza belli cinerea Towns. Seventeen adults, both sexes, San Jabier; 

 Rosarito, February 22 to March 31. To secure a good series of this very local and 

 strongly characterized subspecies was one of Mr. Brown's particular missions to 

 this region. He found the bird to be not very common at the places at which he 

 collected. 



Spizella socialis arizonae Coues. Two adults, male and female, Santana, March 

 20 and 24. 



Spizella atrogularis (Cabanis). One adult male, Santana, March 19.
