152. Callipepla squamata ( Vig .) Gray. Scaled Quail. 
— These Quail were usually met with in the most barren places, 
often in deserts miles from any water. They were common- 
ly found in flocks of from six to ten, but as many as thirty were 
occasionally seen together. They were so shy and difficult to 
obtain that Mr. Stephens rarety got more than one from a flock. 
He traced them westward to Picacho Station (Southern Pacific 
Railroad) beyond which point he thinks they do not extend. 
Some time since I called attention* to certain points of difference be- 
tween Texas and Arizona specimens of the Blue Quail, suggesting the 
name '‘fallidaf for the Arizona representative in the event of its proving 
distinct. More recent examination of material from various localities 
has confirmed the stability of these differences, which are certainly suffi- 
cient to warrant the recognition of a new race. I find, however, that 
Vigors describedf the pale interior form, which accordingly must stand 
as C. squamata , the Texas bird being the one eligible for a new name.f 
As the the two have been more or less generally confused by authors I 
find it necessary to rearrange their characters as follows : — : 
Callipepla squamata {Vigors') Gray. Scaled Quail. 
Adult $ (No. 5870 — collector’s No. 183 — near Tombstone, Arizona, 
April 9, 1881. F. Stephens). Head with a broad, convex, but not con- 
spicuous crest of lengthened feathers. Above faded ashy-brown with a 
faint bluish cast on the nape and tail; beneath brownish-white, nearly 
uniform, but with a trace of ashy on the breast; entire head, including 
the throat, cheeks, forehead, crown and occiput (but not the crest), nearly 
uniform pale brownish-drab, without markings; feathers of nape, back 
anteriorly, and the breast, narrowly but sharply margined with black, giv- 
ing the effect of imbricated scales, the feathers of the breast having in 
addition a concealed, obtusely-V-shaped marking of brown ; feathers of 
the abdomen with transverse, sub-terminal, irregular bars of rusty-brown : 
.those of the crissum wfith shaft streaks of rusty ; tips of long feathers of 
the crest, inner edges of tertials, and shaft-streaks on feathers of the 
flanks, yellowish-white ; no rusty patch on the abdomen.

X In addition to the names Ortyx squamatus and Callipepla squamata, the synonymy 
of the species includes only two titles ; viz. Callipepla stienua, Wagler, Isis, XXV, 1832, 
278; and Tetrao cristata, De la, Llave, Registro tremistre, I, 1832, 144. Wagler’s diag- 
nosis clearly applies to C. squamata proper ; I have not been able to consult the other 
reference, but from the extracts given by Cassin ( 111 ., I, 1853, p. 133), especially the 
sentence, *‘It inhabits the Mesquite regions in Northern Mexico,” I infer that De la 
Llave also described the same form.
