CYANOLYCA.—XANTHURA. 501 
C. pumilo is a very local species in Guatemala, and it was only in the forests of the 
Volcan de Fuego, lying at an elevation of 7000 to 8000 feet, that we found it in any 
numbers: here it frequented the oak-forests in small flocks of five or six individuals, its 
habits resembling those of its congeners. We never saw it in a living state in the 
department of Vera Paz; but in a collection made near San Pedro Carcha we noticed a 
specimen, and there is an example in the British Museum said to have come from 
Coban. | 
The exact origin of sitrckland’s type has not been recorded; but as it was sent him 
by Constancia, who lived in Antigua, it was probably obtained in the vicinity of that 
town, very likely on the volcano itself.

Our description and figure of this beautiful species were taken from the typical 
specimen described by Mr. Lawrence, which was kindly lent us by the authorities of 
the United-States National Museum. We have no example of it ourselves, and the only 
other one we are acquainted with is in the possession of M. Boucard. Mr. Lawrence, 
in his description, compares it with C. ornata, C. nana, and C. pumilo, but we are inclined 
to think that C. pumilo is perhaps its nearest ally ; there can be no doubt, however, but 
that the species is a very isolated one. The type was obtained during Professor Gabb’s 
expedition to the district of Talamanca, Costa Rica, a little-frequented portion of that 
country lying on the eastern face of the cordillera.

We restrict this generic name to the group of Jays in which green and yellow are 
the predominating colours, which thus forms a natural group containing four fairly 
marked species. The one having the widest range as well as being most distinct 
in its characters is X. incas, a species known to Buffon. This bird is found on the 
slopes of the Andes, from Bolivia to Western Colombia; a second species is found in 
the interior of Colombia; a third in Venezuela; the fourth is that of our country, which 
spreads from the valley of the Rio Grande to Honduras. Curiously enough no member 
of this group of Jays is found in the southern section of our country. In the formation
