NO. 9 BIRDS OF ISLA COIBA, PANAMA—WETMORE 95 
on the webs to Venetian blue; abdomen and under tail coverts pale 
glaucous-blue ; rest of under surface of body Alice blue, except the 
posterior parts of the sides and the flanks, which are orient blue; 
under wing coverts gray No. 9 (light gull gray), somewhat paler 
internally. Bill, tarsi, and feet dull black (from dried skin). 
Measurements.—Males (2 specimens), wing 87.4-89.0 (88.2), tail 
63.0-63.4 (63.2), culmen from base 14.4-14.7 (14.5), tarsus 19.0 mm. 
Females (3 specimens), wing 82.6-86.8 (84.1), tail 59.6-60.4 (59.9), 
culmen from base 13.7-14.8 (14.2), tarsus 18.8-19.5 (19.2) mm. 
Remarks.—The six specimens of this race taken include one imma- 
ture male with wings and tail so worn that it is not included in the 
measurements listed above. The darker coloration of the Coiba birds 
when compared with our long series of Thraupis virens diaconus, 
found from southern México to Panama, is evident on the most 
casual inspection, and it is only with quaesita, which ranges from 
Narifio in southwestern Colombia to northwestern Pert, that the 
form here described shows any similarity. T. v. cana, distributed 
through northern Colombia and northern Venezuela, differs from 
cumatilis more than does diaconus. The subspecific name cumatilis 
signifies the dark blue of the sea.

A male taken at the edge of the high forest on January 7 is an 
individual less than a year old, as shown by the dull grayish-brown 
tail feathers, edged extensively with green. It was about to start the 
molt to adult dress, as is indicated by a single, tiny, new feather 
only partly grown, in one eye-ring. The main migration route of this 
tanager crosses the Caribbean Sea from Yucatan and Cuba to Colom- 
bia, with only occasional individuals wandering to the westward. The 
few previous records from Panama have been of migrants bound 
northward in spring between March 25 and April 9, except for one 
sight record on March 16, 1911. The bird from Coiba is the first one 
for the wintering season, a period when the species regularly is found 
from Colombia to Bolivia.

This winter resident from the north, fairly common in Panama, 
was taken twice on Coiba, a female January 20, and a male in highly
