yellow iit bases; black jugular patch bordered posteriorly by a con- 

 spicuous curved band of clear lemon or deep canary yellow, confluent 

 in the middle portion with a longitudinal area of the same color occu- 

 pying the median portion of breast and abdomen, both strongly, though 

 not sharply, contrasted with the general light apple green color of the 

 under parts of the body; sides of neck, behind black auricular area, 

 distinctly and more or less extensively yellow, this confluent with the 

 above-mentioned post-jugular collar.

Rather large Garrulinse (wing more than 127), with the head, neck, 

 and at least anterior half of the under parts uniform black, the rest of 

 the plumage blue (in some species with white spots at tips of rectrices 

 in female or young). 



Nidijicatioii. — (Essentially as in related genera.) 



Mange. — Mexico to northern Nicaragua. 



This genus is rather difficult to characterize, for the reason that, 

 while the stjde of coloration is remarkably uniform and distinctive, no 

 two of the species agree exactly in structural details. All are very 

 stout-billed, except 0. melanocyanea, which further differs from the 

 rest in haying the feathers of the pileum much developed, especially 

 on the occiput, forming, when erected, a bushy crest, and also in 

 having the posterior half of the under parts blue. C. san-ilasiana has 

 a slender median crest on the forehead composed of narrow, nearly 

 straight, elongated feathers. O. hcfcheii and C. ynvatanka are with- 

 out any crest. C. satt-hhiKmna has the nostrils wholly exposed; in 

 C. yucatanicn they are partly exposed, the nasal plumes being very 

 short; while in C heecheil and O. melanocyanea the nasal plumes are 

 longer, quite covering the nostrils. The wing is decidedly more 

 rounded in C. melanocyanea than in the others, the sixth, fifth, fourth,
