Genus CYANOLYCA Cabanis. 



Cyanolycaa Cabanis, Mus. Hein., i, Oct., 1851, 223. (Type, Cyanocorax armillatus 

 Gray and Mitchell.) 



Neotropical Garrulinte with uasal tufts and sides of head black, con- 

 spicuously contrasted with the color (blue or lavender) of the pileum 

 or throat, and with the frontal feathers more or less erect and l)ristly. 



Nldijlcation. — (Unknown. ) 



Range. — Southeastern Mexico to Peru. Bolivia, and Venezuela, 

 (Nine species.) 



The above imperfect diagnosis characterizes a group of Neotropical 

 javs which are obviously related to one another more closely than to 

 any others, the very considerable difference between certain specific 

 types rendering- a more satisfactory diagnosis difficult. It may be 

 found necessary to subdivide the group and restrict the generic name 

 Cyanolyca to C. armillata and its nearer allies {laerlda/na^ qamdlmui., 

 t'lircom., jolyxa, and mrldicyanea); but in this case it would be neces- 

 sary to make three additional genera for the four Central American 

 species, only two of which {C. ornata and C. cacullata) are closely 

 allied. 



Cyanolyca is related to Aphelocoma through two small species of 

 southern Mexico and Guatemala {C. nana and C. pumlld)^ which with 

 the coloration of Cyanolyca have the more slender form of Aphelocoma.
