[Formicivora ornata Sclater, Rev. Mag. Zool, (2) v. p. 480 (1853,.—Nova Grenada). } 
M. a. hoffmannsi Hellmayr, Bull. Brit. Orn, Cl. xvi. p, 84 (April 1906.—Itaittba, left bank of the 
Rio Tapajéz) ; Nov. Zool. xiv. 1907. p. 22. 
M. ornata (not of Sclater) Pelzeln, Zur Orn. Bras. ii, p. 81 (Salto Theotonio, Ribeirio, Rio 
Madeira). 
Nos. 79, 379. $$ ad., Calama, 19. vi., 11. viii. 1907—Wing 51, 53; tail 
34, 35 ; bill 14 mm. 
“Tris brown, feet plambeons, bill blackish grey.” 
These examples agree with the type in all essential points, especially in having 
the apical spots to the wing-coverts deep buff (pure white in M. 0. ornata) and the 
throat deep ochraceous (not black spotted with white), but differ slightly by the 
rather brighter ochraceous colour of the breast and abdomen. This, however, is not 
likely to be a constant character. Both specimens have very little ferraginous 
admixture in the middle of the back, while in the female of M. o. ornata the entire 
back (except pileam and nape) is bright chestnut-rafous. Another difference is to 
found in the colour of the axillaries and under wing-coverts, which are pure white in 
M. o. ornata, bright buff in M. 0. hoffmannsi. 
Dr. von Lorenz has very kindly sent for my examination the two males obtained 
on the Rio Madeira by the late Dr. Natterer. They agree well with the type and 
belong undoubtedly to M. 0. hoffmannsi. The latter form has recently been met 
with by Miss Snethlage on the banks of the Tapajéz and Tocantins Rivers.* 
217. Myrmotherula haematonota (Scl.). 
Formicivora haematonota Sclater, Proc. Zool. Soc. Lond. xxv. 1857. p. 48 (June 1857.—Chamicuros, 
Eastern Peru). 
Myrmotherula haematonota Pelzeln, 1.c. p. 81 (Borba) ; Hellmayr, Nov. Zool. xiv, 1907. p. 384 
(Borba, Humaytha). : 
Nos. 171, 243, 253, 288. go ad. and vix ad., Calama, 6, 19, 22, 29. vii. 1907. 
“Tris yellow or pale brown, feet dark grey or plumbeons, bill black.”—Wing 
50—53 ; tail 36—42; bill 134—14 mm. 
These specimens, adults with the back and rump deep ferruginous, agree 
perfectly with a series from the Caura Valley, Venezuela. The male obtained 
near Borba, by Natterer, is immature, having the tips to the upper wing-coverts 
deep buff, and but a limited space in the middle of the back dark ferruginons. 
About the identity of M. haematonota and M. pyrrhonota cf. my remarks in 
Nov. Zool. xiv. 1907. p. 70, 
Miss Snethlage has lately recorded M. haematonota from Villa Braga, left bank 
of the Rio Tapajéz.t
