A.O Sennett on Nerv Birds frotn Texas. [January 



From material at my command it seems to me tlie species can 

 be further divided by separating the large Southern Brazilian form 

 from the one found on and near the equator. I hope to make this 

 revision in the near future. Should my supposition prove correct 

 the large Southern Brazilian bird should be called Nyctidromus 

 \_alblcollis\ derSyanris Gould (Icon. Av. II, 1838). Of this form 

 I have had opportunity to examine the series of 27 specimens 

 belonging to the American Museum of Natural History, collected 

 by Mr Herbert H. Smith in the Province of Matto Grosso, Brazil. 

 I have been aided greatly by all the material relating to this 

 group in the possession of the National Museum, which was kindly 

 loaned me by Mr. Ridgvvay. 



Parus carolinensis agilis, subsp. nov. Plumbeous 

 Chickadee. 



Top of head and throat black; wings and tail edged with white, as in 

 carolinensis. Above pale plumbeous; below white with the slightest pos- 

 sible wash of buff on sides and flanks. Size, larger than carolinensis, and 

 the tail longer, more nearly approaching the length of the wing. 



Type, No. 3S94, my collection, taken by J. M. Priour, Bee Co., Texas, 

 Jan. 2, 1887. Wing, 2.45; tail, 2.40; culmen, 38, 



The measurements of three other adults are as follows: No. 406,$, Col- 

 lection of J. A. Loomis, Paint Rock, Texas, Feb. 21, 1887: wing, 2.-^2; 

 tail, 2.52; culmen, .37. No. 4218, my collection, April, 1S87 : wing, 2.47; 

 tail, 2.25; culmen, .37. No. 4219, J, my collection, April 15, 18S7 : wing, 

 2.40; tail, 2.25; culmen, .40. I have also two full grown and two half 

 grown young, taken in April, which resemble adults. 



This new Chickadee can be distinguished from its nearest ally, 

 P. carolinensis., by its whiter underparts ; by its being almost 

 entirely free from buii' washings on sides, and from olive and 

 brown washings on upper parts ; and its very pale lead color on 

 back. 



Habitat. Texas (Bee, Victoria, and Concho Counties) . 

 I have difficulty in finding a name that will apply to any of the 

 bird's special characteristics which has not already been used for 

 some species of this genus. The common name, however, will 

 distinguish it from other forms of Parus.
