50 BIRDS OF THE REPUBLIC OF PANAMA PART 4 



vol. 41, 1951, p. 113) thorough study of records of Gabb's itinerary 

 concluded that the specimen was collected "near and more or less north 

 of Pico Blanco," which is near the southern end of the Cordillera de 

 Talamanca. Sipurio, which Pitelka mentions also, is lower down on the 

 Caribbean slope in the area drained by tributaries of the Rio Sixaola. 

 In older collections in the British Museum there are 2 specimens col- 

 lected by Arce, without other data, except that they are marked "Vera- 

 gua," a term applied earlier to the whole of western Panama. 



Modern records with definite locality for argentigula, mainly those 

 in the Monniche collection (Blake, Fieldiana: Zool., vol. 36, no. 5, 

 1958, pp. 545-546) , all lie on the Pacific slope. Bangs ( Proc. New Eng- 

 land Zool. Club, vol. 3, 1902, p. 57) listed a series of 11 taken by W. W. 

 Brown in June 1901 from Volcan de Chiriqui, 3000 m. Bangs loc. cit., 

 p. 16) says that Brown collected "for a short time in June on the north- 

 ern or Caribbean exposure of the volcano" from which the species has 

 been included by Blake as from the Caribbean drainage. This is not 

 certain, however, as Brown worked mainly near or above Boquete. 

 From there the old trail to the Cerro Punta area was a usual route, 

 which would have taken him into the area where I found this jay com- 

 mon, on the Pacific slope. 



Eisenmann and others have seen this species frequently above Cerro 

 Punta, western Chiriqui (on the trail to Boquete) between 1920 and 

 2190 m, in pairs or small flocks, uttering a rather nasal, but not loud, 

 chaak, cheuk, check. 



The race of the mountains of the Cordillera Central, farther north in 

 Costa Rica, marked by paler, whiter throat and crown markings, was 

 named Cyanolyca argentigula albior by Pitelka (cit. supra, p. 114) from 

 a male in the Smithsonian collections obtained by Ridgway and Zele- 

 don on Volcan Turrialba.
