FAMILY PICIDAE 545 



(64.8), oilmen from base 21.1-24.1 (22.9), tarsus 19.3-23.7 

 (20.9) mm. 



Resident. Locally fairly common. On the Pacific slope through the 

 eastern sector of the Province of Panama (Chepo, Cerro Chucanti) 

 and Darien (Tuira Valley, Jaque) ; on the Caribbean side from north- 

 ern Veraguas (probably), the lower Chagres Valley (Rio Pequeni, 

 Barro Colorado Island) through San Bias (Bahia Caledonia, Perme, 

 Puerto Obaldia) . 



The report for Veraguas, a male in the British Museum marked 

 as taken by Arce in 1875, probably was collected on the Caribbean 

 slope as there are no records on the Pacific side west of San Antonio 

 on the lower Rio Bayano beyond Chepo. The bird has been found 

 occasionally on Barro Colorado Island and elsewhere in the lower 

 valley of the Rio Chagres to the lower Rio Pequeni above Madden 

 Lake. It is most common in Darien through the Tuira-Chucunaque 

 Valley. 



This is a forest species, but unlike the other race, found in Bocas 

 del Toro, comes out in open areas in gallery forest, and in the forest 

 growth bordering the rivers. I have found it occasionally in solitary 

 guarumos (Cecropia) and other trees standing in clearings. Oc- 

 casionally it mingles with the little bands of forest birds that move 

 about in loose company. In the Jaque area countrymen said that they 

 came out in the plantations to feed at ripening bananas. The birds 

 move about quietly, occasionally uttering low chattering calls. 



The drumming of the males suggests that of Centurus pucherani, 

 but is slightly slower and not quite as long. A female taken near the 

 Candelaria Hydrographic Station on the lower Pequeni on March 8, 

 1961, was laying. 



The salivary glands extend for about three- fourths the internal 

 length of the lower jaw, the abundant secretion being strongly 

 adhesive. 



The race mentalis ranges beyond Panama across northern Colombia 

 to the lower valley of the Rio Magdalena.

This supposed species, known only from the type specimen, without 

 locality, has been listed as from Panama, but without definite basis. 

 The description is as follows: "This form, of which I have only a 

 female in my collection, is most nearly allied to C. elegans, from which
