74 Brewster on a Collection of Arizona Birds. 
On a former occasion* I urged the specific distinctness of this Thrasher 
from H. redivivus , and to this conviction I still hold, although a compar- 
ison of additional specimens of both species inclines me to believe with 
Dr. Coues that Leconte’s Thrasher is, on the whole, more nearly related 
to redivivus than to any other United States form. 
616, $ ad., near Maricopa Wells, July 5. Length, 10.80; extent, 12.30; 
wing, 3.85 ; tarsus, 1.27; tail, 5.35; culmen (chord), 1.30; bill from

617, $ ad., same locality and date. Length, 10.60; extent, 12; wing, 
3.78; tarsus, 1.32; tail, 4.91; bill (chord of culmen), 1.32; bill from nos- 
tril, .94; width below posterior angle of nostril, .24. “ Iris reddish brown ; 
bill black; legs nearly black. Stomach contained a small species of katy- 
did and some ants.” 
9. Harporhynchus crissalis Henry. Crissal Thrasher. 
— Not uncommon near Tombstone, Tucson and Camp Lowell. 
Dr. Coues, comparing this species with Le Conte’s, Palmer’s, 
and Bendire’s Thrashers, concludes: | ‘ t and we are led to infer 
that when the ‘topography’ of the other three species is fully 
determined, it will be found no less extensive. For there is noth- 
ing peculiar in the economy or requirements of any one of the 
four in comparison with the rest.” This view, however, is hardly 
supported by the testimony of observers who have had the best 
opportunities of studying these birds. The Crissal Thrasher, 
according to Captain Bendire,J “appears to prefer damp locali- 
ties near water-courses, and confines itself principally to spots 
where the wild currant is abundant.” Mr. Henshaw says : “ Ac- 
cording to my experience, it is not a bird of the plains, but inhabits 
by preference the rough sides of rocky canons or the hill-sides 
covered with broken debris, interspersed with straggling bushes.” 
Mr. Stephens’ evidence is not less explicit. He found the Crissal 
Thrasher in copses in valleys, and along streams. It was espec- 
ially fond of well-shaded undergrowth, and spent much of its time 
on the ground, searching for food under the bushes. It never 
occurred among cactuses, and the only place where he 
saw it actually associating with Bendire’s and Palmer’s 
Thrashers, was at Camp Lowell, where the latter species, with 
other desert birds, came to drink at a water-hole and thus occa- 
sionally mingled with the Crissal Thrashers which inhabited the 
neighboring thickets. The contrast which these traits afford
