Tityra nigriceps gualeae n. subsp. — I ^ "/a, near Gualea, 

 4500 f. This bird agrees essentially with T. nigriceps Allén, 

 but differs from the same in having the hind part of the crown 

 (beginning on a level with the posterior orbit) and the nape 

 heavily streaked with pure white. The tail is black, the cen- 

 tral feathers greyish white basally for about 35 mm., but the 

 lateral ones only for about 20 mm., and also bordered with 

 black externally. The quills are also tipped with white. The 

 back and innermost secondaries greyish white, lower parts 

 almost pure white. Length of wing 122 mm. 



We consider this race as the representative of T. nigri- 

 ceps on the western side of the Andes.

The young males recorded above as having transitory 

 jDlumage show much of the juvenile plumage, which is similar 

 to that of the females, but ha ve acquired the adult feathers 

 on the head including the crest and mostly on the lower parts, 

 but on the chest many juvenile feathers remain. On the back 

 new and old feathers are mixed, rather irregularly. The first 

 primary has the same shape as in the female, and the colour 

 of the wings is also similar with that of the female, except 

 that in one of the specimens the innermost secondaries is 

 somewhat shaded with grey.
