14S A Catalogue of Birds found in Costa Rica. 



name of A. plagiata, Licht. {Nomend. Was. Berol., p. 3). 



Distinguished by its stouter form, larger dimensions, and the 

 greater number of its tail bands. 



I have no Costa Rica specimens at hand, but examples in my 

 collection from Panama, as well as from Mexico, agree quite 

 well with the measurements given by Mr. Schlegel. 



Two adult specimens from Panama have their wings 9£ and 

 10 inches, and their tails 7 and 7^; an adult from Jalapa, Mexico, 

 had the wing 10 inches, the tail G.V ; another specimen in young 

 plumage, also from Mexico, has the wing 9i inches, the tail 7i : 

 the tail of the last is light brownish-gray, crossed with seven dark 

 brown narrow bars on the central leathers, increasing to twelve 

 bars on the outer feather ; this specimen agrees closely with Mr. 

 Schlegel's description of A. plagiata, which was taken from 

 specimens in the Berlin Museum. These are in immature plum- 

 age, and were obtained near Vera Cruz, Mexico. Mr. Schlegel 

 says. "Queue avcc douze bandes brunes," &c. In my speci- 

 men, this number of bars exists only on the outer tail feather. 



452. Geotrygon caruleicejps. 



AVhen I described this bird as new, it apparently was so, with 

 the knowledge then possessed of the individual species in the 

 genus G'r<>//'/(/on ; in other words, it differed from all that were 

 recorded as being members of thai genus. At that time Mr. 

 Sclater considered his G. chvriquensis (described /'. '/.. &, 1856, 

 p. 143) to be the same as the species well known to ornitholo- 

 gists as (1 . alh'tfdcirx, although their supposed identity was only 



discovered about the time of its announcement. See Km/. <> r . 

 nit/,., Jan., 1808, Part v., p. 77, pi. xxxix. 



Such being its position when my description of cosruleiceps 

 was written, there was no reason why I Bhould consult the origi- 

 nal description of chiriquensis, for, of albifacies t which was 

 stated to be identical with it, I had many specimens before me. 



Messrs. Sclater and Salvia subsequently found, on examination 

 of the type of G. chiriquensis in thegalleryof the Jardin des 

 Plantes, that they had committed an error in considering it the
