Agreeing with specimens from S. Panlo (Natterer coll.). In South Brazilian 

 skins the ashy frontal band is always much narrower, the cap and shoulder-patch 

 are mnch deeper ferrnginons, and the tail more tinged with rnfescent than in the 

 ndrtheru form, S. albcsce//s albigiilaris Scl.

No. 2370. ? fere ad., Rio Araguaya, August 1906. Type of species. 



Top of the head and nape raw umber-brown (Ridgw. iii. 14) ; back, rump and 

 upper tail-coverts bright cinnamon-rufous, the lower rump rather paler than the 

 rest ; upper wing-coverts, inner secondaries and outer webs of all the other remiges 

 clear cinnamon-rufous, inner webs dusky. Tail uniform cinnamon-rufous, the shafts 

 below whitish. Lores, narrow superciliary streak, reaching to the posterior border 

 of the ear-coverts, and cheeks cream-butf; auricular region rather darker, buif- 

 brownish. Throat white, more buify in the malar region ; foreneck, sides of the 

 belly and under tail-coverts pale buff; middle of breast and abdomen to a great 

 extent white. Thighs buff. Axillaries and under wing-coverts ochraceous-buff ; 

 inner webs of remiges broadly edged with vinaceous-cinnamon. Edge of wing 

 bright buff. Bill blackish, lower mandible horny whitish, feet dark brown.— Wing 

 61; tail 73; bill 14 mm. 



This species is somewhat intermediate between S. gujanensis (Gm.) and 

 S. alhilora Pelz. It agrees with the latter in having the upper tail-coverts and 

 inner secondaries cinnamon-rufous ; but the whole back is also of this colour (instead 

 of being fulvous-brown mixed with cinnamon in the middle of the mantle); the 

 nnder-jiarts are white, washed with buff on the foreneck and sides (not uniform deep 

 ochraceous), and the axillaries as well as the nnder wing-coverts much paler 

 ochraceous. In the two last points the new form agrees with S. gujanensis, which, 

 however, has the back and upper tail-coverts earthy brown, and the inner secondaries 

 dusky, narrowly edged with rufous. 



At the reqtiest of Mons. G. A. Baer the species is named in honour of 

 Mons. Eugene Simon, of Paris, the great authority on spiders and humming-birds. 



99. Synallaxis scutata scutata Scl. 



Synallaxis scutata Sclater, P.Z.S. Loiul. 1850. p. 191 ("Brazil," so. Bahia ; cf. Cat. Binh Brit. 

 Mus. XV. p. 49) ; Allen, Bull. Amer. Mus. v. 1893. p. 112 (Chapada, Mattogrosso). 



No. 2170. ? ad., Rio Thesouras, May 1906.— Wing 56J ; tail 66; bill 14 mm. 



No. 2309. 6 ad., Rio Araguaya, July 1906.— Wing 56i ; tail 6.j ; bill 14 mm. 



No. 1675. ? ad., Faz. Esperan(ja, December 1905.— Wing 55J ; tail 67 ; bill 

 13i mm. 



While almost identical on the nnder-parts, these specimens present a certain 

 amount of individual variation as to the colour of the back. In No. 1675 back, 

 rump and upper tail-coverts are uniform bright cinuamou-rufons (Ridgw. iv. 16)
