374 ON MAMMALS AND BIRDS FROM EASTERN PERU. [Apr. 18, 
5. THAMNOPHILUS LORETOYACUENSIS, Sp. NOv. 
Similis Th. atricapillo, sed dorso cinereo nigro mixto, nec brunneo. 
Hab. Loretoyacu. “Iris brown”? (Haurwell). 
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 7’. atrica- 
pillus, and has the back and vent cinereous.” The bird called 
T. atricapillus (P. Z. 8. 1873, p. 273, no. 10), which I obtained on 
the Upper Ucayali river, is the same as the present species. 
6. GRALLARIA MACULARIA, Temm. 
Loretoyacu. 
A male of this rare species. ‘‘ Iris yellow.” 
7. TITYRA SEMIFASCIATA, Spix.

. 37, Jan. 1880.

11. ARA MACAVUANNA, Wagl. 
Elvira. ‘Iris grey; naked skin round the eye yellow.” 
12. HypotTriorcuis RUFIGULARIS (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 PHALZNOIDES (Vieill.). 
Loretoyacu. ‘“ 2. Iris bright yellow.” 
14. TrRINGOIDES HYPOLEUCOs, L. 
Elvira. ‘“ Iris brown.” 
15. CRypTURUS BALSTONI, Sp. Nov. 
Species similis C. asperso, sed ventre cinereo et lateribus dorso 
concoloribus distinguenda. 
Hab. Elvira. “ 3. Iris light brown” (Hauswell).
