TROGLODYTES. 1-43 



Troglodytes iuquietus. 



Trofjlochjles inquietus, Lawrence, MSS. 



Troglodytes hjpsedon, Lawkexce, Ann. X. Y. Lye. VII, 1861, 320 

 (Panama R. R. ). 



Hah. Isthmus of Panama. 



(109, 9.) First primary much developed ; mX)re than half the longest. Color 

 ahove brown, with a grayish tinge towards the head, and slightly rufous on 

 the rump. Exposed surface of wings and tail barred with black (more obso- 

 letely on wing coverts), the dark bars rather the narrower. The back faintly 

 barred. Beneath pale fulvous whitish, lighter on throat and middle of belly ; 

 tinged with brown on sides, the posterior parts of which are faintly barred. 

 Crissum barred conspicuously with black, the interspaces yellowish-brown to 

 whitish. Quite a distinct superciliary line. No spots on wing coverts. 



Of the two specimens, the % is considerably lighter, almost white beneath. 



(109, 9 , Panama R. R.) Total length, 4.50 ; wing, 2.05 ; tail, 1.85 ; gradua- 

 tion, .45 ; exposed portion of 1st primary, .85, of 2d, 1.31, of longest (measured 

 from exposed base of 1st primary), 1.55 ; length of bill from forehead, .67, 

 from nostril, .43, along gape, .76 ; tarsus, .76 ; middle toe and claw, .72 ; hind 

 toe and claw, .59 ; claw alone, .26. 



This species was at first considered by Mr. Lawrence to be the 

 same with hypeedon (intermedins) ; but a careful comparison with 

 type specimens has shown their distinctness. It is considerably 

 larger, with longer bill and legs. The first primary is much larger. 

 The colors beneath are paler ; the lower part of sides distinctly 

 barred. The upper parts are considerably grayer. 



None of the other small American allied Wrens before me (except 

 T. hrunneicollis) have a first primary decidedly more than half the 

 length of longest, and their tails are longer. The coloring above re- 

 sembles almost exactly that of T. parkmanni and the Mexican var. 

 of T. sedon, although the dark bars are more numerous. The under 

 parts are more fulvous; the bars on sides anteriorly less distinct; 

 the bars on the crissum more regular, and better defined. There 

 are no light spots on the wing coverts as in the Xorth American 

 species. 



This species comes nearest sedon and its allies ; while intermedius 

 is more like the South American species, with their comparative 

 absence of bars.
