48 KOTES ON XIPHOCOLAPTES KIDGWAY. 



tail coverts marked like the bell^^, but less distinctly, and tlie general 

 color tinged with tawny. Bill dull ivory-whitish, becoming grayish at 

 base. Wing 5.60, tail 5.00, culmen 2.08 (exposed portion 1.85), depth of 

 bill at angle of gonys .45, tarsus 1.20, middle toe 1.05. 



A mounted specimen in the American Museum of Natural History 

 (Elliot collection, No. 5267, "Bogota"), labeled '■'■ Xiplioeolaptes promero- 

 Xjirhynchus,^^ is somewhat similar to the above, but has the bill less deep 

 and more extensively grayish basally, the ground-color of the pileum 

 darker, the belly quite as distinctly spotted as in some specimens of A". 

 p7'omero2nrhynchus, and only the upperportion of the throat plain whitish, 

 the lower throat being broadly streaked with brown, like the chest. It 

 is in some respects intermediate between X.promeropirhynchus and the 

 above specimen, whatever it may be, but can not be referred to either; 

 neither am I able to refer it to anything else. Its measurements are as 

 follows: Wing 5.25, tail 5.10, culmen 2.05 (exposed portion 1.82), depth 

 of bill at angle of gonys, .40, tarsus 1.22, middle toe 1.02. 



2. Xiphocolaptes albicollis (Liciit.). 



Two mounted specimens in the American Museum of Natural History 

 areverydoubtfully referable to this species. Oneofthem(No.5265)belongs 

 to the Maximilian collection, and is labeled '•'■ Dendrocolaptes guttatus 

 Licht, Fem. Brasilia. M. R. Mas." Compared with lighter colored ex- 

 amples of X albicollis, this specimen agrees with the latter quite closely, _ 

 except in the groundcolor of the pileum, which is distinctly deep I 

 brown instead of blackish, and in the color of the bill, which is paler, or 

 horn color instead of blackish or dusky. Its measurements are as fol- 

 lows : Wing, 5.10; tail, 5.00; culmen, 1.95; depth of bill at angle of 

 culmen, .37. 



TJie other specimen (No. 5266, S , Brazil), belonging to the Verreaux 

 collection is very pale, the ground-color of the breast being a pale broccoli 

 brown, deepening into Isabella color on the flanks ; the grouud color of 

 the pileum is dusky brown, and the chin and throat are pure white. 

 Wing, 5.00; tail, 5.20; culmen, 1.95; depth of bill at angle of gonys, 

 .34. 



It may be that the pale coloration of these specimens is partly due to 

 their long exposure to light in museum cases.
