 brown."— W. N. 



12. Muscisaxicola mentalis, Lafr. et D'Orb. 



" Perhaps migratory. I saw this species for the first time last 

 March in a meadow, running on the ground very fast and moving its 

 tail. It feeds on Coleopterous insects. Irides dark brown." — W. N. 



13. Serphophaga cinerea (Strickl.). 



" Frequents sides of rivers, stony places in streams, and old arches. 

 Hunts on the wing and on the ground. Feeds on Coleopterous 

 insects. Solitary. Irides reddish brown." — W. N. 



14. Cyanotis aZar.&, Licht. 



" Haunts tufts of reeds in an inaccessible swamp a few miles from 

 Lima. In habits and manner of feeding just like the American Marsh- 

 Wren. Feeds on small insects on the reeds. Irides nearly black." 

 — W. N. 



15. Elainea pagana (Licht.). 



"Migratory, arrives in December, departs in June. Feeds on 

 berries of Cestrum auricidatum. I never saw a vestige of an insect 

 on dissecting it. Irides blackish brown." — "W. N.

" Found all the year near Lima. Has all the habits of a Tyrannus. 

 Frequents fields and open plains ; feeding entirely on Coleopterous

I have hitherto referred west-coast specimens to P. nanus, Gould, 

 described (Zool. Voy. Beagle, iii. p. 45) from the Galapagos. Jiut I

 eastern bird. On the other hand, the northern P. mexicanus is

17. Pyrocephalus obsctjrus, Gould. 



"Has all the habits of the last species. I have shot some with a 

 few red feathers on the breast mixed with the others. Irides dark 

 brovMi."— W. N. 



In my American Catalogue (p. 228) I have omitted to insert an 

 important synonym of this species, viz. Myiobius atropurpureus 

 Tsch. F. P. Aves, pp. 24, 156. 



18. Myiobius nationi, sp. nov. (PI. XL fig. 1.) 



" Resorts to bushes of the thickest foliage and in the most unfre- 

 quented places ; hunts on the wing from branch to hranch like a 

 Dendroeca. Makes its nest at the extremity of a slender branch, 

 in the fork. Irides dark brown." — W. N.
