138 THE CONDOR Vol. IX 



Toxostoma cinereum mearnsi Anthony. Twenty-four adults, both sexes, 

 Rosario, San Jabier, and Santana, November, March and April. The skins from 

 Rosario are of course true T. c. mearnsi; those from the more southern localities — 

 San Jabier and Santana — show slight signs of intergradation toward true cinerewn 

 of the Cape region, especially in the black spots on the under parts being rather 

 less purely black, more brownish. 



Toxostoma rediviva helva Thayer and Bangs. Toxostoma rediviva helva, 

 Thayer and Bangs, Proc. New Eng. Zool. Club, Vol. IV, fi). iy-i8. Afril 30, 

 iQoy. One hundred and thirty-four specimens, both sexes, Roario, October 25 to 

 November 26. 



Toxostoma lecontei arenicola Anthony. Thirty-two specimens, adults and 

 young of both sexes, San Jabier, March 27 to April 7. This Thrasher must breed 

 very early in the season as nestlings at this date were fully fledged, many of them 

 full grown. All young birds including those practically full grown have the bill 

 much shorter than the adults. In color the young are much like the adult except 

 in being rather more fulvous, especially on belly and under tail coverts, and less 

 "bleached." The adults are all in rather worn and faded plumage. 



Planesticus migratorius propinquus (Ridg.). One female, Rosario, Novem- 

 ber 15. 



Polioptila caerulea obscura Ridg. Three adults, two males and a female, 

 Santana and San Jabier, March 14 to April 1. 



Polioptila calif ornica Brewster. Four adults, three males and a female, Santana 

 and Rosarito, February 24 to March 17. These skins show some signs of being 

 intermediate between P. ;pliii}ibea and P. calijornica. The white edge of the 

 outer rectrix is wider than in true P. californica, tho it is black next the shaft, 

 and the gray of under parts is darker than in P. ^lumbea more nearly as in P. 

 californica. The color of the back is about intermediate between that of typical 

 examples of the two forms, being darker than in P. plitmbea, but not so dark nor 

 so slaty as in P. californica. 



Heleodytes brunneicapillus affinis (Xantus). Fifteen specimens, adults of 

 both sexes, Santana and San Jabier, March. This series represents a form de- 

 cidedly nearer to affinis than to bryanti. In only one character do these skins 

 approach bryanti and that is in the spotting below which is usually heavier than in 

 Cape St. lyUcas specimens; still some skins in the series differ even in this respect 

 but little from true H. b. affinis. Anthony {Atili, Vol. XII, p. 280, 1895) says 

 he would expect to find intergradation taking place between the two forms at no 

 great distance south of San Fernando, but that skins from that place are nearer 

 bryanti. A nest with three fresh eggs was taken from a cactus, three feet from 

 the ground, March 17 at Santana. 



Thryomanes bewickii cerroensis (Anthony). Ten adults, both sexes, Santana, 

 San Andris, San Jabier and Rosarito, February 27 to March 31. These are in all 

 respects quite like skins from Cerros Island, and the Cerros Wren is therefore not 

 an island form but occurs also in the adjacent parts of the peninsula of lyower Cali- 

 fornia. Nelson and Oberholser have examined this series and agree with us that 

 the specimens are identical with Cerros Island examples. 



Salpinctes obsoletus obsoletus (Say). One adult female, Santana, March 19. 



Auriparus flaviceps lamprocephalus Oberholser. Four adults, three males and 

 a female, Santana and Rosarito, March. These all are referable to the Cape St. 

 Lucas form, being small, the wing in the series measuring: 6 49.5, 49.5 and 51; 

 ? , 48.5. 



Aphelocoma californica obscura Anthony. Two adults, male and female,
