were long considered the same. They differ in the colour of the head, that of 
C. guatemale being tinted blue, that of C. virenticeps (as its name implies) green. . 
C. gquetemale does not seem to be a common bird in Mexico, and we have only seen 
a few specimens from the State of Vera Cruz. Sumichrast, however, states that it 
occurs near Chimalapa, which we suppose to be the village of that name on the Isthmus 
of Tehuantepec 1°. In Guatemala we found it to be very local, but common in the 
lowland forests of Vera Paz, and, when staying at Choctum, where it is called by the 
natives “Cho-cho,” we secured several specimens from flocks which frequented the 
edge of the small patch of open savanna at that place. These flocks commence flying 
from tree to tree soon after daybreak, and in the evening they are again restless and 
noisy. As usual with all Parrots, a flock consists of a number of birds which keep in 
pairs both when at rest and when flying about. 
Southward of Guatemala the only certain localities for the occurrence of this species 
are Omoa, where Leyland obtained the type, and San Pedro, whence Whitely sent 
specimens*. Mr. Nutting’s record of it in Nicaragua is wrong, so Mr. Ridgway tells 
us, and refers to a young specimen of C. auropalliatus.

C. virenticeps is the Costa Rica and Chiriqui form of C. guatemale, and was separated 
from that bird by Count Salvadori in his Catalogue of the order 1°. The difference is 
slight, but apparently constant, and consists in the colour of the head being green 
instead of distinctly blue. 
It has been noticed by most of the Costa Rica collectors, and M. Boucard found it to 
be common at San Carlos in February °.
