Niger, supra chalybeo-nitens; crista elongata ad basin nigra undique expandente: gula tota calva, rubra; 
carunculo pectorali quoque calvo, plumis elongatis sparsis tantum ad ejus apicem: rostro nigro, pedibus 
plumbeis. Long. tota 16-0, ale 10:0, caude 4°7, rostri a rictu 2°2, tarsi 1°9. 
@ mari similis, sed obscurior ; capitis plumis minus elongatis ; gula tantum utrinque calva, linea mediana plu- 
mosa vestita, carunculo parvo. (Descr. maris et femine ex Turrialba, Costa Rica. Mus. nostr.) 
Hab. Costa Rica, Turrialba (Arcé, Carmiol), Tucurriqui (Arcé), San Carlos (Boucard’), 
San José (v. Frantzius®), Angostura and Dota Mountains (Carmiol®); PanaMa, 
Cordillera de Chiriqui 1 (Warszewicz +), Cordillera de Tolé, Calovevora (Arcé). 
The first specimens of this species sent to this country were obtained by Warszewicz 
in the Cordillera of Chiriqui at an elevation of about 8000 feet above the sea; these 
were described by Gould in 18501. It was subsequently found in Costa Rica, where 
M. Boucard tells us it occurs in the forests at all altitudes up to an elevation of 10,000 
feet’. Its peculiar cry renders it easily detected in the forests which it frequents. 
Unlike C. ornatus of the Amazons valley, C. glabricollis appears to be strictly confined 
to the high mountains, and this is probably the reason it does not occur in the low- 
lands bordering the Panama Railway, and why its northward extension is determined by 
the valley of the San Juan river. 
Suborder TRACHEOPHONA. 
Fam. DENDROCOLAPTIDA*. 
Within our limits we are more or less acquainted with about forty-six species of 
Dendrocolaptide, the total number contained in the family being about 300. The focus 
of the family is probably the great basin of the Amazons river; but its members as a 
whole are by no means confined to the forests of the more tropical countries of South 
America, for the large section or subfamily of the Furnariine belongs chiefly to the 
southern portions of the continent, to the arid districts bordering the Pacific Ocean, 
or to the highlands of the Andes throughout their length. This subfamily is not 
represented in Central America. 
The other subfamilies of Mr. Sclater’s arrangement (Cat. Birds Brit. Mus. xv. p. 3) 
are :— 
* The Dendrocolaptide forms another of the characteristic families of South-American birds, and is strictly 
confined to the Neotropical-Region, with the exception of the Antilles, where no representative is found.
