senting each other geographically. In structural details—shape of the nostrils, 
wing-formula, and form of the tail—they are practically identical, and differ only 
in slight colour characters. 
(a) E. striaticollis striaticollis (Lafr.). 
Central and Bastern Brazil: Bahia (many specimens in various collections 
examined) ; Goyaz : Rio Araguaya (Natterer, Baer); Mattogrosso: Chapada (Smith),

with the green of the back. Nasal feathers and lores white. Cheeks and ear- 
coverts pale brown. Throat white and, like the chest, very distinctly streaked with

back. Wing: dd 53—55, ? ? 48—50; tail: dd 44—45, ? ¢ 37—40 mm. 
Examined. 1 8 ad., Villa Bella de Mattogrosso ; 2 dd ad., Rio Araguaya, 
Goyaz; 14,1, 8. Isabel, Rio Madeira ; 9 ad. and juv., Bahia ; 1(?) ad., Lower 
Amazons (Hahnel). 
(6) E. striaticollis iohannis Snethlage. 
Euscarthmus iohannis Snethlage, Orn. Monber. xv. p. 193 (1907,—Monte Verde, Rio Puriis). 
E. zosterops (nec Pelzeln) Snethlage, Journ, f. Orn. 1908. p. 12 (Monte Verde, Rio Puris). 
Hab. W. Brazil: Monte Verde, on the Rio Puris. 
Characters. Differs from the preceding form by its rusty buff (not white) lores 
and eyelid, paler brown legs, and by having the whole pileam (from the forehead 
to the nape) uniform green like the back. The edges to the upper wing-coverts 
are slightly more yellowish green, the axillaries deeper yellow than in EL. s. 
striaticollis. Under parts exactly as in the latter: throat white with conspicuous 
blackish streaks, breast and abdomen bright yellow, chest slightly washed with 
greenish. 
Type of species: Pari Museum, No. 3539. dad., Rio Puris (Monte Verde), 
February 20, 1904.—Wing 55; tail 43; bill 12 mm. 
N.B.—By mistake the type was recorded s.n. £. zosterops in Miss Snethlage’s 
report on the Purts collections. 
(c) E. striaticollis zosterops Pelz. 
Euscarthmus zosterops Pelzeln, Zur Orn. Bras. ii. p. 173 (1868.—part. ; descr. et hab. Marabitanas ; 
ef. Nov. Zool. xiv. 1907 pp. 355-6) ; (?) Salvadori & Festa, Boll. Mus. Torino xiv. no. 362. p. 5 
(1899.—Rio Santiago, Eastern Ecuador),

E. s. iohannis, frontal edge slightly mixed with ashy. Lores and eyelid dull white, 
cheeks and ear-coverts ashy, faintly tinged with olive posteriorly. Median and 
greater upper wing-coverts dusky, each feather with a well-defined, pale yellow 
apical spot, forming two distinct wing-bands. Under parts pale, “ primrose- 
yellow” (Ridgw., Nomencl. vi. fig. 13), chin nearly whitish; throat obsoletely 
* San Carlos, though not mentioned on p. 173, is included among the localities given under the 
heading of the species in the general list (p. 102 of Pelzeln’s work).
