200 Obkrhoi^skr, Synopsis of tAe Genus Psaliripart/s. LApr 



Type locality. — Limpia Canon, near Fort Davis, Texas. 

 Geographical distribution. — Southwestern Texas, southern New 

 Mexico, southern Arizona, and northern Mexico. 



Resembles P. m. hdus, but the back is almost clear plumbeous 

 instead of light brown. Specimens from northern Mexico (Chihua- 

 hua) show intergradation with iulus, so that P. lloydi must be con- 

 sidered a subspecies of P. melanotis. 



Adult males of lloydi are of course distinguishable at a glance 

 from the very distinct Psaltriparus plumbeus., but females and 

 young require to be examined more closely. The adult female of 

 the former differs from both sexes oi plumbeus in having a distinct 

 blackish streak along each side of the head above the auriculars. 

 Young males present generally a greater contrast between the 

 color of the head and back than is seen in plumbeus., and, further- 

 more, nearly always have, even when very young, some black or 

 blackish brown on the sides of the head or neck, with often a 

 narrow black or blackish collar on the hind neck, — this, however, 

 frequently incomplete or partially obscured. Young females have 

 but very slight indication of blackish on the sides of the head, 

 sometimes none, in which latter condition they cannot with cer- 

 tainty be separated from plumbeus. 



The type of Mr, Ridgway's Psaltriparus santaritce is an imma- 

 ture male of lloydi., as a careful examination shows, and it can be 

 easily matched by young male specimens from any part of the 

 range of the latter.
