Heilprin’s jay seems to be a rare bird in collections, and little has 
been published about it. It differs at a glance from its other congeners 
by having the frontal crest. 
Of the three adult males, two are considerably abraded and are less 
purplish, more brownish above and below than the third example. 
One of the abraded males and the adult female show signs of molt, 
especially in the tail. The immature birds are essentially like the 
adults in coloration. 
» When he wrote his account of this jay Hellmayr (Catalogue of the 
birds of the Americas, pt. 7, 1934, p. 25) had seen only seven specimens, 
distributed among four museums. The present series is therefore a 
sizable addition to the available material of this form.

The specimens from Venezuela are somewhat paler than the one 
from Brazil, especially on the abdomen and upper back, and all the 
present specimens are paler on these areas, than are birds from Rio 
Combirciato, Peru, from Napo, Ecuador, and from Barrigon, eastern 
Colombia. Chubb (The birds of British Guiana, vol. 2, 1921, 588- 
589) uses the name hyacinthinus for the British Guiana bird on the 
basis of its being paler in coloration than examples from eastern Peru, 
Ecuador, and Colombia. It would seem from this that the name 
hyacinthinus Cabanis might be revised for the birds from Guiana to 
Venezuela and adjacent parts of northern Brazil. On the other hand, 
Hellmayr (Catalogue of the birds of the Americas, pt. 7, 1934, p. 28, 
footnote) records that an old faded specimen from British Guiana is 
somewhat duller than skins from upper Amazonia, but that birds
