38 BIRDS OF SOUTHWESTERN MEXICO. 



I feel confident of being correct in referring the bird before me to 

 Syrnium squamulatiim, and thereby establishing its validity. By late 

 ■writers, it has been considered identical with S.virgatum, Cass. This spec- 

 imen is clearly distinct from Mr. Cassin's species, in which the coloring is 

 much darker throughout, having the throat and breast of a dark brown, 

 which in >S^. squanndatum are white ; the light markings on the upper 

 j)lumage of ^S*. virgatum are rufous and in wavy lines, not, as in the 

 other, in distinct whitish spots; the sides are dull fulvous; the thighs 

 dark reddish-fulvous, with irregular narrow brownish bars ; in 8. squa- 

 mulatum the thighs are of a very pale clear fulvous and immaculate. 

 There are but five bars on the tail of 8. mrgatum, the other having six. 

 The two species do not diifer materially in measurements, except that 

 the tarsi of 8. squamulatum are much longer. 



The only description I have found of this species is by Bonaparte 

 (Cons. Av. i, p. 53), with which the specimen under examination agrees 

 closely. Bonaparte was not acquainted with 8. virgatum^ but probably 

 noticed in Mr. Cassin's description some similarity to that of 8. squamu- 

 latum^ as he has, /. c, " Quid Syrnium virgatum^ Cass."

" Iris orange-yellow ; cere and lorum greenish-yellow ; toes yellow. 



" Quite common in the large forests of the eastern coast of Mexico ; 

 it appears very rarely in the plains of the Pacific, where probably iso- 

 lated individuals alone are found. This bird has the habits of the 

 buzzards; it never leaves the woods, awaits its prey perched, and lives 

 principally upon rats and other small quadrupeds."
