not specify the localities where his specimens were obtained, merely 

 remarking that he obtained T. fuscus (including, of course, both species 

 under this name) first in the forests of the river Itabapuana, between 

 the parallels of 21° and 22° south latitude, apparently a tributary of 

 the Paraguay, and afterwards in the forests of the river Belmoute, in 

 Eastern Brazil (province of Minas Geraes). If he met with these birds 

 at only these two localities and obtained only the two specimens which 

 formed part of his collection, it seems very probable that the type of 

 T. fuscus came from the former locality, thus considerably extending 

 the range of the species. 



Sclerurus brunneus Scl. 



Sclerurus brunneus Scl., P. Z. S., 1857, 17 (Bogota) ; (?) 1858, 62 (Rio Napo) ; Cat. Am. 

 B., 18G2, 149 (part).— Salvin, Ibis, 1885, 419. 



Sp. Char. — Uniform reddish-brown or chocolate, the chin and upper 

 throat white with brown or dusky margins to the feathers.* 



Hab. — Colombia, 



Young (No. 17505, Mus. Comp. Zoo!., Bio Ingador, near Pacific coast, 

 Colombia; A. Schott). — Prevailing color deep chocolate-brown, the 

 under parts paler and duller (intermediate between light vandyke- 

 brown and bistre) ; tail brownish-black ; feathers of chin and upper 

 throat white, broadly margined with blackish-brown ; chest tinged with 

 burnt-umber, the feathers with indistinct shaft-streaks of pale tawny. 

 Wing, 3.30; tail, 2.30; exposed culmen, .77 ; tarsus, .83 ; middle toe, 

 .72. 



I have not seen an adult specimen of this species, which Mr. Salvin 

 regards as valid (cf. Ibis, 1885, p. 119), which opinion is certainly de- 

 cidedly indicated by the single immature example now before me. Ac- 

 cording to Dr. Sclater (P. Z. S., 1857, p. 18), it differs from its nearest 

 allies as follows : " From 8. caudacutus of Brazil [i. e., 8. umbretta 

 (Licht.)] and 8. mexicanus * * * of Mexico and Guatemala it dif- 

 fers in the waut of the bright rufous coloring in the rump and fore- 

 neck. In this respect it would seem to resemble Hartlaub's S. guate- 

 malensis * * * but that bird is said to be of the size of 8. caudacu- 

 tus, to which the present species is inferior in dimensions." 



Sclerurus lawrencei, sp. nov. 



Sp. Char. — Similar to S. guatemalensis (Hartl.), but much larger 

 (wing, nearly 1.00; tail, 3.00 or more) ; the coloratiou of lower parts in 

 the adult exactly as iu the young of that species. 



Hab. — "Bahia" (but locality probably erroneous). 



Adult female (Coll. Am. Mus. Nat. Hist., " Bahia" ; Lawrence collec- 

 tion). — Above, warm bistre-brown, changing to burnt-umber on rump 



* The characters ascribed iu the original description, freely translated, arc as fol- 

 lows: "Above, brown tinged with cinnamon; beneath, slightly paler; throat mixed 

 with white ; wings find tail-feathers with inner webs blackish, external margins sim- 

 ilar in color to the back ; bill black, the base yellowish ; feet black. Total length, 

 6.00; wing, 3.40; tail, 2.10."
