 (18,279, Fort Buchanan, Arizona, December; Dr. Irwin.) Immature (8,109 ^, Copper 

 Mines, Arizona). The blue, excojit tliat of the wings and tail, replaced by dull ash; 

 the blue feathers appearing in scattered patclies. 

 Hab. Arizona (Copper Mines, J. H. Clark; and Fort Buchanan, Dr. Irwin, U. S. A.). 



The nearest ally of this race is the var. sordidu of Mexico, which, how- 

 ever, differs in many important respects ; the differences between the two 

 being giving in the synopsis (page 880), it is unnecessary to repeat them 

 he#e. In both there is a tendency towards a party-colored bill ; each exam- 

 ple of the northern style, and most of those of the southern, having more 

 or less whitish on the lower mandible. 



Nothing definite is known as to the habits or reproduction of this bird.

Sp. Char. Tail rounded, but little graduated ; lateral feather aliout a quarter of an 

 inch shortest. Wings longer than the tail ; when closed, reaching nearly to its middle. 

 Above and on sides of head and neck bright blue ; the lores blackish ; the middle of the 

 back slightly duller, the tips of some of the feathers dark brown. Beneath brownish-ash, 

 paler on the chin and towards the anal region, which, with the crissum, is white. No 

 trace of white or Ijlack on the sides of the head, nor of any streaks or collar on the 

 breast. Length, (fresh,) 11.50; wing, 6.00; tail, (dried,) 5.40; tarsus, 1.50. 



Hab. South side of valley of Rio Grande, near the coast, and southward. 



Tliis well-marked species is quite different in form from the C californica, 

 having a shorter, more even tail, much longer wings, and stouter feet. The 

 absence of any collar or streaks on the breast and throat, of Ijlack or white 

 on the side of the head, and of decided ash on the back, are very well 

 marked features. There is also much more green in the blue of the head. 



As suggested in the P. R. R. Report, the birds collected by Lieutenant Couch 

 at Monterey, IMexico, although agreeing almost exactly with the original de- 

 scription of Bonaparte, are much smaller, and perhaps entitled to recognition 

 as a separate form. The tail is nearly two inches less, 5.40 instead of 7.00, 

 or over. 



Habits. Tlie Ultramarine Jay is a well-marked species, and is specifically 

 quite distinct from the C. californica. It is found in the valley of the Rio 

 Grande, and thence southward and eastward in the northern provinces of
