200. Helminthophila celata lutescens. Lutescent Warbler. — 

 Rather common spring and fall migrant in the Catalinas, altitude 4000 

 feet, and it probably breeds in the pine forests of this range in the higher 

 altitudes. (See Auk, Vol. II, No. 4, p. 352, October, 1885.) The first 

 spring arrivals (Catalinas, at 4000 feet) in 1885 were on April 3, and it 

 was quite common until May 6 of the same season. Not seen later. In 

 the fall I observed it in the same locality from September 3 until the first 

 week in October. 



201. Dendroica olivacea. Olive Warbler. — The only notes of this 

 species which I have, have been already recorded in this journal. (See 

 Auk, Vol. II, 1SS5, pp. 172 and 352.) 



202. Dendroica sestiva [morcomi. Western] Yellow Warbler. — 

 A rather common migrant and summer resident throughout the region, 

 and found breeding in the Catalinas up to 4500 feet. My earliest spring 

 record is March 30, 1885. 



[Eleven specimens in Mr. Scott's collection show this newly named 

 subspecies to have a more than usually satisfactory basis. Mr. Coale 

 founded his separation (Bull. Ridgw. Orn. Club, No. 2, April, 18S7, p. 

 81) of this form apparently on specimens from Fort Bridger, Utah. Judg- 

 ing from his description our Arizona specimens are considerably paler 

 than Utah ones. A female (No. 2331) taken April 27, 1885, is so very 

 pale as to show no decided yellow below, the lower parts being merely 

 pale, soiled, yellowish white, and there is no decided yellowish anywhere 

 except on the top of the head, upper and lower tail-coverts, edges of the 

 quills, and inner vanes of the tail-feathers. The other spring females 

 show a more or less decided wash of yellow over the lower parts, and of 

 greenish yellow above. In one the yellow is a little stronger, and there 

 are slight traces of reddish streaks on the sides of the breast. Both males 

 and females are strikingly different from D. (Estiva of the East, and the 

 wonder is that the form was not earlier separated, judging by the Arizona 

 specimens. — ]. A. A.] 



203. Dendroica coronata. Yellow-rumped Warbler. — Not nearly 

 so common as D. audiiboni, but I think of regular occurrence as a migrant. 

 I have seen several specimens in the collection of Mr. Herbert Brown, 

 of Tucson, one of these being taken on January 28, 1S86. 



204. Dendk-oica auduboni. Audubon's Warbler. — A common mi- 

 grant, and a few probably breed in the pine forests of this region. They 

 winter in small numbers in the valley of the Santa Cruz, about Tucson, 

 and also in the valley of the San Pedro River. (For further references 

 to the species see Auk, Vol. II, No. 4, p. 352, October, 1885.) 



205. Dendroica graciae. Grace's Warbler. — The only point where 

 I have observed this species is in the pine forests of the Santa Catalinas 

 in the spring. (For details see Auk, Vol. II, No. 4, p. 352, October, 

 1S85.) A pair that were apparently mated and about to nest, were taken 

 in tlie pine forests of Mount Rice. Catalina Range. April 30, 1SS5. They 

 are catalogued as No. 2349 J, and No. 2348 $, in the collection made by 

 me in this region. 



206. Dendroica nigrescens. Black-throated Gray Warbler. —
