510 CRACID^. 



Adult. Very nearly allied to 0. guttata, but can be distinguished 

 by having the forehead whitish grey ; the feathers of the chest and 

 upper breast rather narrowly margined all round with whitish; the 

 lower back and rump brownish olive, scarcely differing in colour 

 from the mantle ; and by its greater size. Total length 22 inches, 

 wing 8'8, tail 10-5, tarsus 2-4, middle toe and claw 2-4.

Ortalida albiventris, v. Pelz. Orn. Bras. p. 286 (1870) [Matto-Grosso ;

Adult. Very closely allied to 0. albiventris, but apparently the 

 top of the head is always dark greyish brown or greyish black, 

 never brownish chestnut ; while the underparts are darker and of a 

 brownish-white colour. The lower back and rump in specimens 

 from Bolivia are distinctly browner and less rufous ; but specimens 

 from the Upper Amazons and U.S. of Colombia are quite inter- 

 mediate in this respect. Total length 19 inches, wing "-"J, tail 9, 

 tarsus 2-3, middle toe and claw 2-3. 



It seems to me exceedingly doubtful whether the present species 

 is worthy of specific rank, as with a larger series from intermediate 

 localities the two extremes will probably be found to completely 

 intergrade.
