side Quito. »This bird has a very wide range from Santo 

 Domingo de los Colorados up to Quito 9500 f. Only one or 

 two birds are seen at a time. They usually remain in the gar- 

 dens 2 or 3 days and then disappear. » (L. S.) It has thus the 

 unsteadiness of the migrating bird.

Pyranga rubriceps rufistigmata n. subsp. — 2 (^(^ ^/^, 

 below Baeza, 5500 f . These birds are otherwise similar to the 

 western specimens, but they ha ve the long under primary 

 coverts tipped with rufous, instead of yelloiv, as is the case 

 with the western specimens. This difference is, of course, 

 rather slight in itself, but taken together with the geograph- 

 ical distribution, it is of eonsiderable interest as it confirms, 

 that seldom if ever the birds on the western and eastern sides 

 of the Andes are quite alike. 



The type of Pyranga rubriceps was from Bogota without 

 any more definite indication of its origin. It is of course 

 possible that birds from »Bogota» may have been collected 

 on the western, or on the eastern side of the faunistic bound- 

 ary-line, but as the uncertainty in this case makes it impos- 

 sible to decide anything, definite we select the western form 

 as the type.
