504 Mr. P. R. Lowe — Observations 



Differs from C. niaf/nirosiris, its Andean all}', in being a 

 smaller bird with smaller wings and mncli smaller and 

 more curved bill. The coloration in the two species is 

 nearly identical. In C. pac'/fica the bills are also smaller 

 than in C. mexicana, and the bird is paler above and 

 below. 



There are only four specimens of this Pacific sea-board race 

 in the British Museum; but I have examined two others 

 from coast localities in the Tring collection which exactly 

 agree with it, 



I at first thought this form might be Cabanis' C. peruviana 

 (J. f. 0. 1865^ p. 413) ; but Cabanis' description agrees more 

 closely with that of C. magnirostris of Taczanowski ; for he 

 says his specimen (a somewhat imperfect one obtained by 

 the traveller Warscewicz) is almost identical in size and 

 coloration Avitli C. majuscula. The latter is very similar 

 to C. magnirostris. but lacks the wing-spot and is altogether 

 larger than C. pacifica. 



Moreover, Cabanis' gives no measurements and says that 

 " the exact locabty is missing, probably it is in Eastern Peru, 

 and thus the bird is identical with one referred to by 

 Von Tschudi." 



Tschudi's C. jlaveola was presumably described from the 

 eastern slopes of the Peruvian Andes, which is the home 

 of C. magnirostris, and of which I consider it a synonym. 



In addition to this. Dr. Reichenow informs me that the 

 type of C. peruviana is missing. 



Consequently, with so mucli uncertainty attaching to the 

 name which Cabanis gave to his Peruvian bird I think it 

 would be better, instead of regarding it as identical with 

 C. magnirostris, over which it would have priority, to sink 

 Cabanis' name altogether.
