12 BIRDS OF SOUTHWESTERN MEXICO. 



This is an abumlant species in Western Mexico, to which section it 

 seems to be restricted ; common at Mazatlan, and also obtained on the 

 Tres Marias Islands by Colonel Grayson.

7. ff^rporEiyBBflBHs caarvirostris (Sw.). 

 "tehnacan (Pnebla) ; August, 1868.

8. MinBiiis poly^lottMS var. candatus, Baird.

" Iris orange-yellow ; bill and feet black." 



9. MioBauiii gracilis, Cab. 



" Tehuantepec City ; October, 1869. 



" Iris orange-yellow ; bill and feet black." 



There are six specimens which I consider to be this species. They 



differ from examples from Yucatan in being rather smaller and more 



slender; in having the wings and tail brownish black, and the color of 



the upper plumage of a brownish ash. In Yucatan specimens, the wings 



and tail are deep black, and the upper parts bluish ash. These last 



agree closely with Cabanis's description of M. gracilis. The specimens 



under examination were collected in October. The differences in color 



mav be seasonal.
