36. Dandroeca auduboni ( Toxvns. ) Baird. Audt'box's 

 Warbler. 



343- J '^^■- Tucson, May 7. Length, 5.80; extent, 9.52: wing. 3.05 ; 

 tail. -:-7,v '"Iris dark brown; bill and legs black." 



37. Dendroeca nigrescens {Toxvns.) Baird. Black- 

 throated Gray Warbler. — On April i. Mr. .Stephens se- 

 cured five males of this species amonfjc the Chiricahiui Aloinitains. 

 The only additional specimens in the collection are two females 

 taken late in the season (No. 203, 9 ad., Cienecra Station, April 

 iv No. 357. Santa Rita Moimtains. IMav 12.). 



38. Dendroeca townsendi (N'ntt.) Baird. Townsexd's 

 Warbler. 



2.98, $ ad., Tucson, April 28. Length, 5.10; extent. 7.70; wing, 2.45. 

 •'Iris dark brown ; bill and legs black ; soles of the feet \ellow. Among 

 mesquites." 



373. $ ad.. Santa Rita Mountains. May 13. Length, 5.30: extent. 8.10: 

 wing, 2.64. 



374. 5 ad., same locality and date. Length. 4.90; extent, 7.40; vving, 

 J. 44. "Iris dark brown ; soles of feet yellowish. Water oaks of foot-hills : 

 ver}- 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 pm-e and unmixed. 



39. Siurus naevius (Bodd.) Cones. Northern \^'ater 

 Thrush. — A single specimen taken May 4. at Tucsosi. 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. Ridg\\'a\- kindl\- furnishes the following opinion 

 regarding its relationship with .S. uotabilis. "The Siurus tVom Tucson 

 is very different in proportions tVom the type of iiotahilis. with which I 

 have compared it, but it inav be a small individual of that t'orm. 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 grajer, the streaks beneath 

 much narrower, and the spots on the throat much smaller." Notcibilis. 

 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, (J 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. Verv fat. .Stomach contained insects."
