lateral stripes of black mixed with brow n, separated bj a broad median 

 stripe of smoke-gray, but tending to coalesce on the hindneck; broad 

 superciliaries also smoke-gray, slightly paler than the median stripe; 

 a transocular stripe of brownish black; sides of the head and neck 

 smoke-gray; below white, the breast tinged with smoke-gray, and the 

 flanks and under tail-coverts bnffy cream-color; "iris brown; feet 

 horn-color; bill black, leaden blue below." 



Measurements of type. — Wing, 72 mm.; tail, 56; exposed oilmen, 15; 

 tarsus, 22. 



Remarks. — The series of Arremonops from various localities in the 

 Orinoco region and northern Venezuela is fairly uniform save for 

 this one specimen, and agrees closely with a similar series from the 

 Santa Marta district of Colombia, which had formerly been referred 

 to A. conirostris caucus Bangs. Naturally I assumed that the odd 

 specimen belonged to A. Venezuela! sis Ridgway, inasmuch as it 

 seemed to fit the description very well indeed. Imagine my surprise, 

 therefore, when I came to examine the type of the latter, to find that 

 it pertained to the ordinary bird of Venezuela and Colombia, to which 

 I had been applying the name caucus. The question at once arose as 

 to the true application of this latter name — a matter which I am able 

 to discuss from a re-examination of the type specimen, kindly loaned 

 by Mr. Bangs. After a critical comparison of this specimen I feel 

 very sure that it is an unusually large and richly colored individual of 

 the common Arremonops of the region. I base this statement on the 

 ground that several examples in the series before me approach it in 

 both these respects. In this view of the case the name venezuelensis, 

 having a few months' priority over canens, w r ill supplant the latter 

 as the proper name for this form — assuming that it differs from true 

 conirostris, described by Bonaparte {Conspectus Avium, I, 1850, 488) 

 from " Brasil." This author's type should be examined, as he speaks 

 of it as being "subtus albo-rufescens." 



It is of course possible, on the other hand, that the unique type of 

 A. tocuyensis may be an unusually small and dull-colored individual of 

 venezuelensis, but I find no specimens of the latter which approximate 

 it in its distinctive characters. It is of about the same size as A. 

 super ciliosus; the back has very little greenish tinge — decidedly 

 less than venezuelensis; and the sides of the head, and the median and 

 superciliary stripes are smoke-gray, not slate-gray, as in the latter.
