352 Mr. P. L. Sclater on some recently 



I add some remarks on the other types of Dendrocolaptidce 

 in the U.S. Nat. Museum, which have been sent to me for 

 examination. 



(1) Phacellodomus inornatus, Ridgway, Pr. U.S. Nat. 

 Mus. 1887, p. 152. 



I confess I am not inclined to separate this Venezuelan 

 form specifically from P. frontalis. Two specimens from 

 Venezuela in my collection show the rufous front very plainly, 

 though it is not quite so well marked as in typical Brazilian 

 skins. I have examined specimens of what I consider is the 

 same bird from Peru (Stolzmann), Pernambuco {Forbes), 

 Bahia [Wucherer), Matto Grosso [H. H. Smith), Bolivia 

 {Bridges), and Salta, rep. Arg. {Durnford). 



(2) Dendrornis punctigula, Ridgw. MS. 



This form from Costa Rica I consider barely separable 

 from Dendrornis erythropygia, originally described from 

 Mexico (P. Z. S. 1859, p. 366), but of which I have a series 

 before me, in my own and the Salvin-Godman collections, 

 extending through Central America to Panama, Ecuador, 

 Venezuela, and Bolivia. The principal question, to my mind, 

 is whether the difference between D. erythropygia and the 

 nearly allied D. triangularis can be maintained. The main 

 distinction is the red rump of D. erythropygia, which is not 

 apparent in D. triangularis of the highlands of Colombia*. 



* It is only fair to say that Mr. Ridgway does not accede to this view. 

 He writes to me as follows upon this point : — 



" As to the Dendrornis, I admit that my ' new ' bia'd is what has been 

 called JD. erythropygia, from Costa Rica and Veragua, bat, at the same 

 time, claim that it is different. True D, erythropygia, from Guatemala 

 and Southern Mexico, is a smaller bird, with smaller and more cm-ved 

 bill, much lig-hter coloration, especially above, where the hind neck and 

 upper back are conspicuously streaked, and with the markings on the throat 

 narrower, or in the form of bars or luuules rather than spots. In fact, 

 the Central-American (^. e., Costa-Rican and Veraguan) bird looks to me 

 much more like D. triangtdaris, from Colombia and Ecuador, the principal 

 difference being that D. triangtdaris has the pileum and nape distinctly 

 'guttated' and the rump less rufescent. These distincticns I find fully 

 borne out bv the following series, now before me : —
