U. S. P. R. E. EXP. AND SURVEYS ZOOLOGY GENERAL REPORT. 
This genus has a much narrower and more depressed hill than Ptilogonys. The feet are 
similar, but'with more curved claws, and with no feathers on the upper part of the tarsus. The 
first quill is much larger ; indeed it can scarcely he called spurious ; the fourth, fifth, and sixth 
are successively a little longer than the third ; the outer primaries not acuminate. The tail is 
much broader, widening to the tip ; it is rounded, or graduated, instead of forked. The head has 
a crest of narrow linear feathers, instead of a short, broad, and full one.

Sp. Ch.— Head with an elongated occipital crest. Exposed portion of spurious quill about half the length of the second, 
which equals the secondaries ; sixtli quill longest. Tail graduated. Male throughout ofa uniform lustrous black, glossed with 
green. Inner webs of the primaries white, except at the base, tips, and margins. Female, ash color, paler beneath ; the quills, 
wing, and lower tail coverts and outer tail feathers edged with whitish ; rest of tail feathers blackish. Length of male, 7.75 ;

Hub. — Valley of Gila and southern Colorado to upper Rio Grande ; west to Fort Tejon ; east to Coahuila, Mexico. 
There is some difference in the size of specimens, one from the Colorado desert being con- 
siderably smaller than 3964 from Coahuila. The female has the crest rather less conspicuous 
than the male.
