FAMILY COLUMBIDAE 47 



That the present species was distinct became evident to Lawrence when 

 he received a collection made by J. R. Galbraith and McLeannan in 

 what is now Panama. While the type locality usually is given as the 

 line of the Panama Railway, this may be restricted to that area of the 

 railroad on the Atlantic slope, since Lawrence in his account of the 

 collection says that only a few species, which he enumerates in a list 

 that does not include this dove, were taken on the Pacific side. 



LEPTOTILA CASSINII RUFINUCHA (Sclater and Salvin) 



Leptoptila rufinucha Sclater and Salvin, Nomencl. Avium Neotrop., 1873, p. 162. 

 (Bugaba, and the south slope of Volcan de Chiriqui, Panama.) 



Characters. — Nape and upper hindneck cinnamon, much brighter 

 brown than in typical cassinii; lighter gray on the breast, and some- 

 what brighter brown above. 



A male taken on Cerro Pando, beyond El Volcan, February 28, 

 1954, had the iris Marguerite yellow; edge of eyelids and bare loral 

 area dull rose-red ; bill dull black ; tarsus and anterior part of the toes 

 dull red ; distal half of the toes fuscous. 



A female, collected on the Rio San Bartolo near Puerto Armuelles, 

 Chiriqui, March 1, 1966, had the iris pale yellow, bare lores and line 

 above and below eye dull red ; rest of bare eyelids dull light gray ; cere 

 and bill black ; tarsus and toes light bright red ; claws dull dark brown. 



Measurements. — Males (10 from Chiriqui and Costa Rica), wing 

 129.8-137.0 (134.0), tail 76.2-85.4 (81.4), culmen 13.0-16.5 (14.2), 

 tarsus 32.3-33.7 (32.8) mm. 



Females (10 from Chiriqui and Costa Rica), wing 127.0-136.7 

 (131.4), tail 78.7-87.6 (82.3), culmen 14.0-16.3 (14.6), tarsus 30.6- 

 35.0 (32.0) mm. 



Resident. Found in western Chiriqui, from the lowlands to 1,300 

 meters elevation on the western slopes of the volcano. 



While formerly Veraguas was included in the range, so far as I 

 am aware this was based on specimens received from Arce marked 

 "Veragua" without more definite locality, which apparently came from 

 farther west than the present boundary of the province. All of the fully 

 documented skins that I have seen are from western Chiriqui. The 

 bird is found from the lowlands near Puerto Armuelles and, formerly 

 at least, at Bugaba and Divala, to the forests near El Volcan, and from 

 there west to the Costa Rican boundary. The most eastern locality that 

 has come to attention is Frances, below Boquete, where it was collected 

 by Watson. This race is found also in western Costa Rica. 



Near El Volcan and Santa Clara I noted these doves in dense
