Conurus petzi is the name by which this Parrot is more commonly known, but 
Count Salvadori has shown that it must be referred to Edwards's Red-and-Blue-headed 
Parrakeet, upon which Linneeus’s Psittacus canicularis was mainly founded °. 
It has only one near ally, and that is C. awreus, a common bird over a wide area in 
South America. Both have a wide orange patch on the forehead, extending over 
nearly the anterior half of the crown. C. canicularis has the inner webs of the quills 
blackish instead of olive, the forehead redder and more restricted, and no yellow 
surrounding the eyes. But this last character is sometimes absent in specimens, 
probably young, of C. aureus. 
Conurus canicularis is a very common species in Western Mexico, where it is 
resident according to Grayson !*, and Jouy *? found it in small flocks in the Barranca
