454 Bangs and Noble, Birds of Peru. [£"£ 



These specimens may be somewhat intermediate, but are nearer to 

 cana than to the southern form, true S. cinerea (Strick.). 



This little Flycatqher was seen only along the torrents of the central 

 Andes. It runs nimbly over the rocks, and on several occasions was seen 

 to pick up tidbits from the surface of the stream. 



Tyranniscus uropygialis (Lawr.). One adult female, Tabaconas, 

 September 1. 



We have compared this skin with the type of Lawrence's Mecocerculus 

 uropygialis kindly lent us for the purpose by the authorities of the American 

 Museum of Natural History. The two specimens are very similar. 

 Lawrence supposed his type came from Ecuador. It is a little larger than 

 our bird, but if it is a male — ours is a female — sexual difference in size 

 would just about account for the difference exhibited by the two specimens. 

 The only other point of dissimilarity is that the back in the type is dull 

 reddish olive whereas the back in our bird is olive. This difference is in 

 all probability due to actual fading in the older specimen, such as so often 

 occurs with olive in many species of birds. 



The species is certainly not a Mecocerculus, but so far as we can see is a 

 Tyranniscus. 



The two skins afford the following measurements:

 No. Wing. Tail. Tarsus, culmen.

Camptostoma sclateri (Berl. & Tacz.) Three adults, one male, two 

 females, Huancabamba, August and September. 



Phaeomyias murina tumbezana (Tacz.). Two adults, male and 

 female, Perico and Bellavista, September. 



Elaenia leucospodia Tacz. One adult female, Sullana, July 29. 



Myiozetetes similis connivens Berl. & Stolzm. Five adults, both 

 sexes, Bellavista and Perico, September. 



Our series bears out all characters claimed for the subspecies by its 

 authors, and besides our birds average smaller with slightly smaller bills, 

 than numerous examples from Bahia. 



Mionectes striaticollis poliocephalus Tacz. One adult male, Taba- 

 conas, September 1. 



Leptopogon superciliaris pcliocephalus Cab. & Heine. One adult 

 female, Perico, September 12. 



This specimen obviously belongs with the northern race, and is not 

 different from birds from western Colombia. 



Hellmayr, P. Z. S. 1911, p. 1132 has pointed out that the Central 

 American bird must be referred to poliocephalus unless it represents still
