IA.8 Brewster on Three Ne-w Forms of North American Birds. [April 



George B. Sennett). Arizona apparently furnishes both forms for 

 a specimen from the Catalina Mts. (J, No. 2177, Coll. W. E. 

 D. Scott, April 19, 1SS5) is typical nitidzis, while six others 

 from the same locality are referable to mittalli. The latter, 

 however, do not average as dark as examples from further north. 

 California birds are usually, but by no means invariably, the 

 deepest-colored of all. It is not impossible that both mittalli 

 and nitidtis breed in Arizona at different elevations, or one of 

 them (nitidus) may occur only as a migrant. The evidence at 

 hand seems to favor the latter view. 



In Baird, Brewer, and Ridgway's Land Birds (Vol. II, page 

 417) the female Poor-will is described as "without the white 

 tip of tail." This is obviously an error, for not one of the 

 twelve females before me lacks the white, although in several it 

 is more or less tinged with buff, and is, perhaps, also usually 

 narrower than in the male. 



The material examined in the above connection includes the 

 entire series of the National, American (of New York), and 

 Cambridge Museums, besides those of several private collections, 

 the whole aggregating forty-one specimens — five from Texas, two 

 from New Mexico, sixteen from Arizona, two from Colorado, 

 five from Utah, four from Montana, one from Nevada, and six 

 from California. 



Vireo noveboracensis maynardi, subsp. nov. — Key West Vireo. 



Subsp. Char. — In size and proportions similar to V. crassirostris, the 

 bill equally large and stout. Coloring more like that of V. novebora- 

 censis but grayer above, the yellow beneath paler (but of the same green- 

 ish or lemon tinge) and equally, if not more, restricted. 



Wing, 2.20-2.53; tail, 1.90-2.07; tarsus, .70 -.79; culmen from base, 

 •55--°5; do. from feathers, .42-.50; do. from nostril, .30-.35 ; depth of bill 

 at nostril, .18-. 20 



Habitat. Key West, Florida. 



Types, Nos. 108,860, $ ad., Key West, Fla., March 29, 1886, Str. Alba- 

 tross; 108,862, $ ad., Key West, March 29, 1886, Str. Albatross; both in 

 collection of National Museum. 



In general terms this bird may be said to combine the struc- 

 tural peculiarities of V. crassirostris with the coloring of V. 

 noveboracensis. It has the long, stout bill of the former, the 

 yellow beneath greenish instead of brownish, and essentially
