 1. Xiphocolaptes procurvus Cab, 



Since my "Review" of this genus was printed (see these Proceed- 

 iugs, vol. XII, pp. 1-20), 1 have received through kindness of the au- 

 thorities of the Boston Society of i^atural History a mounted specimen 

 belonging to the Lafresnaye collection (No. 2219) labeled ''Xiphocolap- 

 tes procerus Caban., S. A." While this specimen certainly can not be 

 identified with any of the species which I was able to characterize in 

 my paper, I am unable to determine from Cabanis's very brief descrip- 

 tion whether it is really that species or not. From the descritpion of X, 

 procerus it differs (1) in the wings and tail being wof "lighter cinnamon 

 brown than in X.promeropirhynchuH,'''' and (2) streaks on the under parts 

 not more indistinct than in that species. It agrees with the description, 

 however, in having the bill much larger than in X. promeropirhynchus 

 as well as much paler in color (dull ivory-whitish instead of blackish), 

 though other measurements are about the same. It may be described 

 in detail as follows: 



Most like X. promeropirhynchus, but bill very much deeper and dull 

 ivory-whitish instead of blackish ; general coloration much paler, with 

 streaks on pileum and under jmrts dull whitish instead of strong buff; 

 chin and throat white very faintly tinged with buff instead of deep 

 buff, and belly but very faintly spotted. Pileum and hind-ueck dull 

 light sepia, streaked with dull bufify whitish ; back, scapulars, and wing- 

 coverts dull raw-umber brown ; lower back, rump, and upper tail-coverts 

 bright russet, tinged with cinnamon-rufous; remiges and inner webs of 

 greater and primary coverts chestnut-rufous, the terminal portion of 

 inner webs of primaries (except innermost quills) dull brownish and 

 edges of outer webs, toward base, washed with the color of the back; 

 tail deep chestnut, lighter on outer feathers. Chin and throat plain 

 buffy white; rest of under parts light raw-umber brown, each feather 

 with a broad mesial streak (averaging about .08 of an inch wide on 

 chest and breast) of buffy white, these streaks on the belly margined 

 by very indistinct specks of a deeper hue than the ground-color; under
