NORTHWESTERN MEXICO. 275 



This species, found only in Western Mexico, has until recently been considered the same as 

 the South American P. chrysorjaster. Dr. Finsch, 1. c, gives a full account of the different 

 stages of plumage of this species, and by comparison with the descriptions and figures 

 given by Lesson, and Jardine and Selby of P. chrysogaster, points out their distinguish- 

 ing characters. He says, — " The Mexican variety is unquestionably that described by 

 Vigors, which cannot be united with P. clirysogaster Less., as has hitherto been supposed. 

 Specimens from Peru or Venezuela, which alone can decide that point, are imfortunately not 

 at my command at present." 



I have a male specimen of P. chrysogaster in perfect plumage, from Ecuador, the differ- 

 ence between which and P. chrysopeplus is very striking, especially in regard to size, the 

 yellow coloring of the Mexican bird is much deeper, the sinuated portion of the outer 

 primaries is bordered with white, while in P. chrysogaster the ends of the primaries are 

 wholly black, and the quills of the latter are of a deeper black ; in the other white mark- 

 ings on the wings, and those of the tail, the two species are much alike ; the inner webs of 

 the outer three tail feathers are largely white at their ends in each, Li P. chrysogaster 

 there is a broad black band across the back, the lores and lower eye-lids are black, the occi- 

 put and hind neck are somewhat intermixed with black, and the sides under the wings are 

 sparingly and faintl}' marked with blackish bars ; the back of P. chrysojjejilus has a few 

 of the feathers marked with black, but the plumage of the lores, the hind neck and under 

 the wings is immaculate. 



The two measure as follows : — 



P. chrysopeplus. Length (fresh), 10 m. ; wing, 5 ; tail, 4| ; tarsus, 1^ ; bill, high at 

 base, I ; wide at base, -^|. 



P. chrysogaster. Length (skin), 7^ ia. ; wing, i^; tail, 3^; tarsus, -if; bill, high at 

 base, ^^ ; wide at base, ^\.

The Tres Marias and Mazatlan form proves to be C. igneus Baird. I had no specimen 

 at the time of preparing the Tres Marias hst, but took the name as given in Col. Grayson's 

 notes.
