Many years have now elapsed since I first received this species from Mexico, where it is doubtless as 
plentiful as its near allies are known to be. In the absence of all information respecting its habits I can 
do no more than portray this rare bird in two different attitudes, trusting that the time is not far distant 
when we may hope to receive some account of its manners and economy. 
The Callipepla squamata , although not so brilliantly marked as some other members of the genus, is never¬ 
theless a very pretty species, and is rendered conspicuously different from them all by the lunated fasciae 
which entirely surround the body, and by the shortness of its crest, which is moreover of a soft and hair¬ 
like character. 
Judging from the fact, that wherever a species is not remarkable in its colouring, the male and female 
differ but little in outward appearance, I am of opinion that the plumage of the sexes of the present bird 
is very similar, and that the accompanying figures are representations of both; at the same time this point 
is uncertain. 
Specimens of this species are very rare in collections ; there are two or three in that of the Zoological 
Society of London, and those from which my figures were taken will hereafter form part of the fine series 
of birds in the British Museum. 
Habitat, Mexico. 
The figures are of the natural size.
