1887.1 385 [Ridgway. 



about equal in width to the dusky bands instead of only about half 

 as wide ; breast narrowly barred or transversely lined, instead of 

 spotted, with dusky; middle tail-feathers sharply banded entirely 

 across with dusky grayish brown and very pale brownish gray. 

 Wing 3.30, tail 3.50, exposed culmen .75, bill from nostril .52, 

 tarsus 1.05. 



The true habitat of this species is of course unknown, but, con- 

 sidering the fact that its nearest relative is G. balteatus Baird (cf. 

 Review Am. B., p. 103, in text), it probably inhabits some portion 

 of northern or western South America. 



8. Campylorhynchus megalopterus (Rev. Zool., 1845, 339). 

 Types, 2611 and 2612, Mexico. 



While differing in some particulars, which are probably attribu- 

 table to the more worn condition of their plumage, these specimens 

 agree essentially with specimens of the so-called C. pallescens from 

 Mexico. Compared with five adults of the latter, the differences 

 are found to consist (1) in the darker spots on the lower parts, 

 which are also less tinged posteriorly with pale brownish buffy, 

 and (2) in the decidedly paler and less buffy lighter bars of the 

 rump and upper tail-coverts. 



In measurements they do not differ, as the following may show. 



No. 2611: wing 3.50, tail 3.30, exposed culmen .80, bill from 

 nostril .57, tarsus .95. 



No. 2612 : wing 3.70, tail 3.70, exposed culmen .90, bill from 

 nostril .65, tarsus 1.05. 



No. 32471, Nat. Mus. : wing 3.65, tail 3.25, exposed culmen 

 .85, bill from nostril .59, tarsus 1.10. 



9. Campylorhynchus curvirostris (MS. only?). Type, No. 

 2621, "N. Granada." 



This is a small species allied to C. brevirostris,Jjk*R. and C. zon- 

 atus (Less.), but apparently quite distinct from either, its charac- 

 ters being as follows : — 



Campylorhynchus curvirostris, sp. nov. (ex. Lafr., MS.) 

 Sp. Char. — Similar to C. brevirostris Lafr., but much smaller, 

 with bill slenderer and more curved though proportionally wider at 

 base, whitish bands of upper parts relatively broader, tail much 

 more distinctly banded (the middle feathers banded entirely 

 across) and strongly tinged with dull buffy or fulvous, and spots 

 on lower parts much smaller, those on throat and chest decidedly 

 longitudinal, the belly immaculate buffy. Total length (mounted
