Hylophilus ochraceiceps. 



A single Gnatemalan skin, two from Segovia River, Honduras, three 

 from Costa Rica, and one from Veragna (Cliiri(ini) all ditferfrom the tyi)e 

 from Mexico in being paler below, very few showing the yellowish-browu 

 color of the breast, and almost all with more olive, shading on the sides. 

 Above there is more olive shading on the lower back and rump, and 

 the same color is more noticeable on tlie hind neck. All have the edges 

 of the tail-feathers lighter brown, and basally a perceptible shading of 

 olive not seen in the type; besides, they are slightly smaller in wing 

 and tail measurements. 



Cyclorliis flavipectiis subflavesceus. 



After a study of the literature on the subject and a careful compari- 

 son of a small series of Costa Rican specimens with the difterent forms 

 of Gydorliis in the U. S. jSTational Museum, including the types of 

 -ftavipectus and fiaviventris yucatanensis, I am convinced there is only 

 one species found in Costa Rica, and that is subJiavescenH. The Costa 

 Rican bird, subjiavescens, is separable readily from flaviventris or fJavi- 

 ventris yncatanensis by the white on the belly, which, even in those 

 specimens with the greatest amount of yellow on the under surface, is 

 distinct. This character is enough to distinguish them, but the Costa 

 Rica bird is decidedly and uniformly brighter olive-green above. 



Unfortunately thenumber of specimens o^jiavipectas is limited to four, 

 two of which are referable to Professor Allen's fiavipectus trinitatis. I 

 have fifteen Costa Rican specimens. All agree in having the anriculars 

 dark ash-gray, while m flavlpectus they are pale ash. In addition, the 

 rufous-chestnut superciliary stripe in the Costa Rican examples appears 

 darker and is shorter, not extending to the nape. There are also the 

 ditterences pointed out by Mr. Allen (Bull. Ani. Mus, Nat. Hist., Vol. 

 II, No. 3, p. 131). 



Vireolanius puchellus verticalis. 



Costa Rica examples compared witii the type (also from Costa Rica) 

 agree minutely. 



Diglossa plumbea. 



Young birds are brownish olive above, dusky brownish below, with 

 burty brownish in the center of the belly. 



Daciiis veiiusta. 



Young males probably resemble the females. A young male (No. 

 773, Museo Xacional de Costa Rica), Just assuming adult plumage, has 

 the forehead black like the adult male, and bright blue feathers are 

 scattered in the dusky greenish of the crown. There are a few black 

 feathers in the upper back. The scapulars, lower back, and rump are 

 blue : part of the wing-coverts, <piills, and tail-feathers black, and part
