(Basse-Californie S.). 



It is probable that Mr. Bryant's record of the occurrence of Peucaea rujiceps 

 boucardi at Llanos de San Julian (about latitude 29° N.) relates to the present 

 form, but this cannot be considered assured until the specimen taken (on April 

 19, 1S89) at the locality just named has been carefully re-examined. Mr. 

 Anthony states that Aimophila ruficeps ''seems to be rather- common in a few 

 favored localities along the base of San Pedro " Martir and that " a series of 

 four skins taken between Tia Juana and the base of San Pedro are practically 

 indistinguishable from Southern California examples." ^ 



The specimens collected by Mr. Frazar at Triunfo sustain very satisfactorily 

 the characters ascribed by Mr. Kidgway to sororia. In respect to color and 

 markings, this form is about intermediate between ruficeps and scottii, but its 

 bill is unlike that of either of these races. It seems to be a perfectly good 

 subspecies. 



It was discovered in the Cape Region by Mr. Belding, who found it " common 

 on grassy hillsides above 2,500 feet altitude," and paired in February. Mr. 

 Frazar met with it only at Triunfo, where it was not common in April, and 

 still less numerous in June, the majority probably going further north to 

 spend the summer. A few remained to breed, however, for a female taken 

 on June 23 had evidently laid all her eggs, and was incubating. 



The Laguna Sparrow is believed to be confined to the more southern portions 

 of the Peninsula, but the northern limits of its range are not as yet definitely 

 known. 



Melospiza lincolnii (Aud.). 



LiNCOLif's Sparrow. 



Melospiza Uncolni Beldikg, Proc. U. S. Nat. Mus., VI. 1883, .348, part (Victoria 

 Mts.), 350 (La Paz and s.). Bryant, Proc. Calif. Acad. Sci., 2d ser., II. 1889, 

 303, part (Cape Kegion). 



Mr. Belding found this species less common than the Laguna Sparrow in the 

 mountains, and rare in the low country near the coast. Mr. Frazar met with 



1 Zoe, IV. 1893, 242.
