Xew Species of Jtirds. 07 



mid inclining to dull AvhitisJi on the chin and middle of abdo- 

 men : on the other luind the sui)ej-ciliarv sti-ii)e is i)ure white 

 (excei)t anteriorly), and therefore, on account of the contract, 

 unusually conspicuous; tiie upper ])arts are a much darker and 

 richer olive-green than in the darkest-colored examples of R. sa- 

 //•((pa olivaceus before me, the color changing to deep smoky- 

 gray or grayish-brown on the hind neck ; the olive-green edgings 

 to secondaries, etc., are decidedly brighter or deeper than in 

 R. sntrapa olivaceus, and the broad pale olive-yellowish or whitish 

 bar across the tips of the greater wing-coverts, always distinct in 

 olivaceus and true satrapa, is almost obsolete. The head-pattern 

 appears to be quite the same as in more northern birds, and the 

 color of the markings not appreciably different.*' 



Ml'. Ridgway suggested as appropriate, the name of Regidus 

 mtr((pa aztecus, which I have adopted.

 Ganmer. Type in my collection. 



Bemarks. — Compared with T. inter mecUus, the colors through- 

 out are much lighter, being grayish -white below, instead of light 

 rufous ; the bill is a little longer, but the wings and tail are 

 much shorter ; it differs also in being without the concealed 

 white spots on the rump, which exist in T. intermedius.
