TANAGBIDM. 



Hob. Mexico 2 10 ", valley of Mexico [White ^), temperate region of Vera Cruz {Sumi- 

 chrast% Jalapa [SalUS de Oca\ I>eppe^\ Edge), Orizaba {Botten^ le Strange), 

 Totontepec (Boucard ^), Oaxaca.— Colombia i ^ 9. 



The range of this species is remarkable, inasmuch as it is completely severed into 

 two parts. The northern section is restricted to Southern Mexico, and the southern to 

 Central and Eastern Colombia. The whole of the intermediate country is occupied by 

 the allied species B. gutturalis, apparently to the complete exclusion of B. alUnucha. 



In Colombia it is by no means a common bird ; but not only was it originally 

 described from a Colombian specimen in the Paris Museum, sent by Cande from the 

 neighbourhood of Cartagena ^, but Mr. Sclater has in his possession a skin which is of 

 the unmistakable make of the Bogota bird-hunters ^ ; so that its presence in the south 

 can hardly be questioned. 



In Mexico B. alUnucJia is well known, being, as Sumichrast says, one of the 

 characteristic birds of the temperate region between the elevations of 2000 and 3600 

 feet 3. 



Mr. Sclater speaks of a specimen in his collection which has the throat orange- 

 coloured, showing that the species varies in this respect just as B. gutturalis ®. 



6. Buarremon capitalis. (Tab. XXIII. fig. 1.)

OUvaceus, alls et cauda nigricantibus illis olivaceo limbatis, capita sunino nigro, stria oocipitali, regions post- 

 OGiilari et nucha cinerascentibus ; subtus oleagineo-olivaeeus, gula nigra, gutture imo obscure olivaceo,

Hah. Costa Rica [v. Frantzius ^), Irazu [Arce, Rogers, Boucard *) ; Panama, Volean de 

 Chiriqui [Arce ^). 



Though placed in a distinct genus by Dr. Cabanis, this bird may fairly be included 

 in Buarremon, the only distinction being, so far as we can see, the greater strength of 

 the tarsi and toes. Its habits seem to resemble those of B. hrunneinucha. M. Boucard 

 tells us ^ that it frequents the Volean de Irazu, going in pairs, which spend most of 

 their time on the ground scratching in search of insects. 



The only extension of the range of B. capitalis beyond Costa Rica is the volcano of 

 Chiriqui, where Arce found it and sent us several specimens, one of which is now 

 figured.
