BIRDS OF WESTERN COLOMBIA. 1213 



Western Colombia (cont.). Central America {cant). 



Aulacorliamplius albivitta pliceolcemus §. A. cceruleigularis. 



*Pionopsitta pulchra. P. hcematoiis. 



*Columha goodsoni. C. nigrirostris hrunneicauda. 



*Geotrygon veraguensis cachahiensis . G. v. veraguensis. 



'Notliocercus intercedens, N. frantzii. 



The evidence at hand is hardly sufficient to allow an exact 

 comparison of the fauna of Western Colombia with that of the 

 Central Cordillera, yet from what we know it appears that the 

 Pacific lowlands and foot-hills possess a considerable number of 

 peculiar elements, e. g. Sapayoa cenigma, Cnipodectes suhhrimneus, 

 Carpodectes hopkei, etc. Some of the species recorded only from 

 the Western Cordillera may turn up in the Central Cordillera ; 

 but, on the other hand, it is quite certain that a good many forms 

 that inhabit the central mountain-chain are altogether absent 

 from the Pacific slopes. 



A thorough exploration of Southern and Central Colombia 

 cannot be too warmly recommended to the attention of 

 ornithologists, as offering a wide field for the solution of various 

 zoogeographical problems. 



§ Aulacorhamphus phceol(Bmus Gould, Ann. Mag. N. H. (4) xiv. p. 184 (1874. — 

 Concordia, Western Cordillera of Colombia (and Merida, in Venezuela— errore !)). 



A. petax Bangs, Proc. Biol. Soc. Wash. xxi. p. 158 (1908.— San Antouio, R. Cali, 

 Western Cordillera of Colombia). 



There can be no doubt that the blue-throated AulacorhampJms, of the Western 

 Cordillera, has to bear the name A. a. -pliceolwrnus, which Mr. Bangs appears to have 

 overlooked. Although in the Cat. B. Brit. Mus. xix. p. 158, a specimen from 

 Merida, Venezuela, is given as type, this cannot he correct, for Gould {I. c.) clearlv 

 described the Concordia bird {cfr. "throat deep greyish blue"). It may be 

 mentioned that the Merida form was erroneously referred to phcBolcBmus by Gould, 

 since a series in the Munich Museum undoubtedly belongs to A. a. albivitta, all the 

 examples having the thi-oat white.
