age, with the edges of the greater wing-coverts, remiges and rec- 

 trices, faded and very obviously worn. This may account for the 

 entire absence of the somewhat indistinct lighter and darker spot- 

 ting which characterizes the edges of these feathers in the type of 

 C. unicolor oides, in which the head and neck and the edges of the 

 secondaries have a very strong fulvous-buny tinge, the plumage 

 being in very fresh condition. A specimen in the National Mu- 

 seum collection from southern Brazil (No. 16439, 9 ad., August, 

 1858, Chr. Wood) is decidedly nearer the type of C. unicolo- 

 roides, in coloration, notwithstanding the feathers are somewhat 

 worn. The measurements of the three are as follows : — 



Type of G. unicolor : wing 3.35, tail 3.35, exposed cuimen .80, 

 bill from nostril, .58, tarsus, 1.05. 



Type of C. unicolor vides : wing, 3.55, tail 3.40, exposed cui- 

 men, .85, bill from nostril .58, tarsus 1.00. 



No. 16, 439, U. S. Nat. Mus. : wing 3.55, tail 3.55, exposed 

 cuimen .82, bill from nostril .60, tarsus, 1.10. 



4. Campylorhynchus brevirostris (Rev. Zool., 1845, 339). 

 Types, 2609, Bogota, and 2610, "Mexico.'' 



These two specimens, which are very much alike, and both 

 probably from Bogota, are undoubtedly the young of C. zona- 

 toides, Lafr. (Rev. Zool., 1846, 92). 



5. Campylorhynchus zonatoides (Rev. Zool., 1846, 92). 

 Types, Nos. 2606, "Mexico", 2607, "Columbia," and 2608, "Co- 

 lumbia." 



These are all adults, and agree substantially with Bogota spe- 

 cimens in the National Museum collection. 



6. Campylorhynchus palliceps (MS. only?). Type, No. 2614, 

 "Mexico." 



This specimen agrees minutely with the type of C. balteatus 

 Baird (c/. Review Am. B., 1864, p. 103, in text), the habitat of 

 which is western Ecuador and Peru. 



7. Campylorhynchus pallescens (Rev. Zool., 1846, 93). 

 Type, No. 2613, Lafresnaye collection; "Mexico." 



This is not the Mexican species usually known under this name 

 (i\ e., G. megalopterus Lafr.), but a very distinct one, allied to 

 G. balteatus Baird, from western Ecuador and Peru. From the 

 latter it differs in lighter coloration, the darker markings dusky 

 grayish brown instead of blackish, and white bands across remiges
