FAMILY DENDROCOLAPTIDAE 43 



Salvin in reporting on collections made by Arce (Proc. Zool. See. 

 London, 1870, p. 193) recorded it from Calovevora, Chitra, and 

 Cordillera del Chucii. Later, with Godman (Biol. Centr.-Amer., 

 Aves, vol. 2, 1891, p. 182), Castillo was added, all of these localities 

 being in the uplands of the Pacific side of Veraguas except Calo- 

 vevora which is on the Caribbean slope. Earlier (Salvin, Proc. Zool. 

 Soc. London, 1867, p. 144) had listed Santiago also. Specimens with 

 these localities are in the Salvin-Godman collection in the British 

 Museum, so that it is strange that later collectors have not en- 

 countered the bird in this province. 



In Chiriqui, Arce found it at Bugaba and W. W. Brown, Jr., in 

 1901 collected a series at Boquete. It is interesting that it seems 

 to have become rarer in that area as the only specimen recorded by 

 Blake (Chicago Nat. Hist. Mus. Fieldiana : Zool., vol. 36, 1958, 

 pp. 528-529) in the Monniche collection was one taken at Camp 

 Holcomb, in Bocas del Toro. There is another from that province 

 taken on the Rio Changuena, September 11, 1961, by Rudolfo Hinds. 



In my own field studies I have found these birds fairly common 

 on the western side of the volcano near El Volcan, and from there 

 westward toward the Costa Rican boundary. 



The original description of this race was written by Robert 

 Ridgway, who forwarded the type with his comments to Osbert 

 Salvin in London, engaged at the time in studies of this family. Salvin 

 included "puncfigula, Ridgw. MS" in his account with a summary of 

 their correspondence. Unexpectedly, this appeared in the Ibis for 

 July, 1889, while Ridgway's formal, detailed account was not pub- 

 lished until 2 months later, on September 20. Though both Salvin 

 and Ridgway in their writings later assigned the name to the latter, 

 under the rule of priority in publication it is to be credited to Salvin.
