374 ON MAMMALS AND BIRDS FROM EASTERN PERU. [Apr. 18, 



5. Thamnophilvs loretoyacuensis, sp. nov. 



Sitnilis Th. atricapillo, sed dorso cinereo nigro mixto, nee brunneo. 



Hub. Loretoyacu. "\x\sh\ovin" {Hauxwell). 



This bird is so closely allied to Thamnophilus atricapillus, that I 

 am somewhat reluctant to give it a specific appellation, although 

 Mr. Salvin writes to me and says *' I think the Thamnophilus 

 sufficiently distinct to be worthy of a name," and Dr. Cabanis also 

 writes : — "Concerning your Thamnophilus loretoyacuensis, I believe 

 it to be a good species. This bird is much larger than T. atrica- 

 pillus, and has the back and vent cinereous." The bird called 

 T. atricapillus (P. Z. S. 18/3, p. 273, no. 10), which I obtained on 

 the Upper TJcayali river, is the same as the present species. 



G. Grallaria macularia, Temm. 



Loretoyacu. 



A male of this rare species. " Iris yellow." 



7. Tityra semifasciata, Spix. 

 Elvira. " Iris red." 



8. Galbula chalcothorax, Sclat. Mon. Galbulidse, pi. x. 

 p.- 37, Jan. 1880. 



Elvira. 



9. Piaya cayana, L. 

 Elvira. " Iris red." 



10. CaPITO NIGER (Miill.). 



Loretoyacu. " Iris red." 



1 1 . Ara macavuanna, Wagl. 



Elvira. " Iris grey ; naked skin round the eye yellow." 



12. Hypotriorchis rtjfigularis (Daud.). 

 Nauta. "Iris brown." 



A single skin of this bird was in the collection ; and I am now 

 convinced that many of the small Falcons observed by me during my 

 residence in Nauta were referable to this species, although I could 

 not obtain a single specimen : they were so wild and difficult to 

 approach. 



13. Glaucidium phal^noides (Vieill.). 

 Loretoyacu. " $ . Iris bright yellow." 



14. Tringoides hyfoleucos, L. 

 Elvira. "Iris brown." 



15. Crypturus balstoni, sp. nov. 



Species similis C. asperso, sed ventre cinereo et lateribus dorso 



co7icoloribus distinguenda. 

 Hah. Elvira. " cJ • Iris light brown " {Hauxwell).
