costaricensis falling as a synonym of chiriquensis (unless, indeed, as 

 is of course possible, specimens from southwestern Costa Rica, upon 

 which the above assertion is based, do not really represent costari- 

 censis, described from San Jose). At any rate, Mr. Ridgway is clearly 

 mistaken in referring Santa Marta specimens to chiriquensis, as shown 

 by an actual comparison with the type-series of this form. Birds 

 from the Santa Marta region agree in their slightly paler coloration 

 below with a series from the mountains of Venezuela (for which 

 Dr. Hartert has recently proposed the above name), as compared with 

 another series from the Eastern and Western Andes respectively, 

 which may be regarded as true joseplicc. Summer specimens are more 

 worn, and of course paler, than birds taken at other seasons, and due 

 allowance must be made for this fact in making comparisons. At most 

 the characters assigned to mirandec are very slight, and entirely 

 bridged over by individual variation in both series, so that it is often 

 impossible to satisfactorily allocate a given specimen, and we are 

 recognizing it only with reservations. 



This vireo ranges ordinarily from about 4,000 to 7,000 feet in the 

 Subtropical Zone, so that the record by Mr. Brown from the Paramo 

 de Macotama, at 11,000 feet, seems open to question. It seems to be 

 a rare bird anywhere, in this region as well as in Costa Rica and Vene- 

 zuela, judging from the writer's experience. It is essentially a wood- 

 land bird, being found in or along the edge of the forest, rarely in 

 isolated trees. It keeps high up in the tree-tops, is rather quiet, and 

 on account of its inconspicuous coloration is difficult to make out in 

 the thick foliage.

This well-known North American bird is a common winter resident 

 in the lowlands all around the mountains, but does not range into 

 the foothills. It was first recorded from this region by Salvin and 

 Godman, on the strength of a single specimen shot by Simons near 

 Santa Marta, April 3, 1879. Only one of the above series was taken
