The nt'tii-e,st ally of this rtice i.s tliu var. sordida of ^loxico, which, how- 

 ever, dilliers in many important re.spects ; the dilfereucos between the two 

 being giving in the .synojisis (page 880), it is unneces.sary to repeat them 

 here. In botli there i.s 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 wliitish on the lower mandible. 



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

Sp. Ciiar. Tail rounded, but little graduated ; lateral leather about a quarter of an 

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

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

 bac'k slightly chiller, the tips of some of the leathers dark brown. Beneath browuish-ash, 

 paler on the chin and towards the anal region, which, with the crissuni, is wliite. No 

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

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



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



This well-marked species is (piite different in form from the C. californica, 

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

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

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

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



As suggested in the P. Ii. 1>. Ifeport, the birds collected l)y Lieutenant Couch 

 at Monterey, Mexico, 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 

 finite distinct from the C. cnlifornirn. It is found in the valley of the liio 

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