138 Brewster on a Collection of Arizona Birds. 
36. Dendroeca auduboni {Towns.) Baird. Audubon’s 
Warbler. 
343. $ ad.. Tucson, May 7. Length. 5.80; extent, 9.52; wing, 3.05 ; 
tail, 2.75. “Iris dark brown; bill and legs black.” 
37. Dendroeca nigrescens (Towns.) Baird. Black- 
throated Gray Warbler. — On April 1, Mr. Stephens se- 
cured five males of this species among the Chiricahua Mountains. 
The only additional specimens in the collection are two females 
taken late in the season (No. 203, 9 ad., Cienega Station, April 
15. No. 357, Santa Rita Mountains, May 12.). 
38. Dendroeca townsendi (Nutt.) Baird. Townsend’s 
Warbler. 
2.98, 9 ac R Tucson, April 28. Length, 5.10; extent, 7.70; wing, 2.45. 
“Iris dark brown; bill and legs black; soles of the feet yellow. Among 
mesquites.” 
373 , $ a d.. Santa Rita Mountains, May 13. Length, 5.30; extent, 8.10; 
wing, 2.64. 
374, $ ad., same locality and date. Length. 4.90; extent, 7.40; wing, 
2.44. “Iris dark brown ; soles of feet yellowish. Water oaks of foot-hills ; 
very fat.” 
Even the most adult males of this species seem to have the throat-patch 
slightly sprinkled with yellow. At least I have yet to see one with the 
black absolutely pure and unmixed. 
39. Sinrus naevius ( Bodd .) Cones. Northern Water 
Thrush. — A single specimen taken May 4, at Tucson. It was 
among; willows on the borders of a stream. 
This example differs from New England ones in being darker above and 
less yellowish beneath. In these respects, as well as some minor ones, 
it resembles a rather peculiar style from West Virginia to which I once 
called attention.* Mr. Ridgway kindly furnishes the following opinion 
regarding its relationship with A. notabilis. “The Siurus from Tucson 
is very different in proportions from the type of notabilis , with which I 
have compared it, but it may be a small individual of that form. The 
wing is about the same length, but the bill and tail are very much shorter, 
and the tarsi more slender. The color above is grayer, the streaks beneath 
much narrower, and the spots on the throat much smaller.” Notabilis , 
based as it is on a single specimen, and instituted in a species which varies 
to an unusual degree in size, color and markings, seems to me, however, 
to be, at best, a very doubtful race. 
329, $ ad., Tucson, May 4. Length, 6.20; extent, 9.50; wing, 3.10; 
tail, 2.32; tarsus, .85; culmen, .64. “Iris brown; bill black above, brown 
below; legs light brown. Very fat. Stomach contained insects.”
