NO. 9 BIRDS OF ISLA COIBA, PANAMA—WETMORE 89 
mainder of sides and flanks Delft blue, with a wash of yew green 
where this meets the yellow of the abdomen ; under tail coverts white, 
this color spreading to the posterior part of the flanks; under wing 
coverts and a narrow margin on inner webs of remiges white. Max- 
illa black ; mandible colonial buff; tarsus and toes olive brown (from 
dried skin). 
Measurements.—Males (2 specimens), wing 56.9-58.5, tail 40.5- 
41.7, culmen from base 12.8-12.8, tarsus 16.9-16.9 mm. Females (2 
specimens), wing 53.5-54.7, tail 39.2-39.8, culmen from base 11.7- 
12.6, tarsus 16.7-16.8 mm. 
The measurements of the type, a male, are the larger ones in the 
male series, where a difference in dimension is present. 
Range.—Isla Coiba, off the Pacific coast of Veraguas, Panama. 
Remarks.—The deeper coloration in both male and female sepa- 
rates this new form strikingly from the birds of the mainland. In 
the males, the pattern of the under surface merges from breast to 
abdomen with no distinct line of demarcation in the central area. 
According to Ridgway the wing in males of C. p. speciosa (11 speci- 
mens) measures 47.5-55.0 mm., and in females (2 specimens) 47.5 
to 51.8 mm. 
The subspecific name is taken from the Latin cirrhus, yellowish 
orange, with reference to the predominating color. 
DENDROICA PETECHIA XANTHOTERA Todd: Golden Warbler, 
Canario Mangletero 
Dendroica bryanti xanthotera Tovp, Proc. Biol. Soc. Washington, vol. 37, July 
8, 1924, p. 123. (Puntarenas, Costa Rica.) 
I found these warblers fairly common in growths of red man- 
groves on the shores of Bahia Damas, from the mouth of the Rio 
Catival to near Boca Grande, beyond Playa Blanca, this being the 
area in which mangrove swamps were extensive. They did not range 
inland in stands of other forest as the allied Dendroica p. aequatori- 
alis does on some of the smaller islands, e.g., on Taboguilla, and on 
San José and Pedro Gonzalez in the Perlas group. On Coiba, during 
January these birds were in resting stage, some in molt, and were 
not singing. I found also that they would not decoy, though in the 
display and nesting period they come quickly to a squeak, so that 
my series of nine males and six females was obtained only by close 
and careful watching. Rarely I found one or two in low trees or 
shrubs immediately adjacent to the mangrove border, but most were 
obtained directly in the swamps.
