Grallaria princcps Sclater and Salvin, Proc. Zool. Soc. London, October 1869, 

 p. 418. (Calovevora, Veraguas, Panama.) 



Characters. — More rufous ; adult with breast rufous with few 

 streaks or none ; hindneck lighter gray ; back and wings more reddish 

 brown. 



In a male in the British Museum (Natural History), collected by 

 C. H. Lankester at Cachi, Costa Rica, the label records the iris as 

 "dark brown ; bill dusky horn, fleshy at base ; feet fleshy leaden." 



Measurements. — Males (10 from Chiriqui, Bocas del Toro, and 

 Costa Rica), wing 109.8-113.2 (111.5), tail 35.0-41.5 (38.6), culmen 

 from base 26.7-30.8 (28.8), tarsus 44.4-52.0 (48.8) mm. 



Females (8 from Chiriqui, Bocas del Toro, and Costa Rica), wing 

 109.8-113.2 (111.5), tail 35.0-41.5 (38.6), culmen from base 26.7- 

 30.8 (28.8) mm. 



Resident. Found in small number in the Subtropical Zone from 

 western Chiriqui and western Bocas del Toro to north-central 

 Veraguas. 



This form was first recorded by Salvin (Proc. Zool. Soc. London, 

 1867, p. 146) from a specimen collected by Arce labeled "Santa Fe," 

 listed in this account as G. guatemalensis. When a second specimen, 

 a bird in more adult stage of plumage, came from Arce two years 

 later Sclater and Salvin described the bird of Panama (idem, 1869, 

 p. 498) as Grallaria prince ps. A third specimen from Arce was re- 

 ported by Salvin (idem. 1870, p. 196) as from "V. de Chiriqui." 

 In the original description Sclater and Salvin for the locality list 

 the bird as ''Hah. in Veragua {Arce)." Sclater (Cat. Birds Brit. 

 Mus., vol. 15, 1890, p. 314) lists the two specimens from Santa Fe 

 and Calovevora as "Types of the species." Salvin and Godman 

 (Biol. Centr.-Amer.. Aves, vol. 2, 1892. p. 242) included a description 

 of princeps (in Latin) and at the end say (still in Latin) "Descr. 

 exempl. ex Calovevora, Panama. Mus. nostr." This is accepted as 

 the restricted type locality, and the specimen from Calovevora, a 

 female, is to be regarded as the holotype. As one further comment, 

 the original description in the Proceedings of the Zoological Society 

 of London has the date "June 10, 1869" at the head of the page, but 

 according to records of Charles W. Richmond the actual date of 

 publication was in October. It may be noted also that Salvin (Ibis, 

 July 1869, p. 312) in a paper discussing published records by George 

 N. Lawrence wrote in a footnote "it may be remarked that Grallaria 

 guatemalensis is G. princeps Scl. & Salv." While this appears to be
