Grallaricula perspicillata, Scl. Ibis, 1873, p. 373". 
G. perspicillate quoque similis, sed dorso cinereo immaculato; tectricibus alarum haud maculatis; stria rictali 
nigra nulla; pectore et hypochondriis fulvis, illo vix striato, his quoque unicoloribus, distinguenda. A 
G. intermedia differt tectricibus alarum immaculatis; stria rictali nulla; pectore vix striato et hypochon- 
driis saturate fulvis. (Descr. exempl. typ. ex Tucurriqui, Costa Rica. Mus. nostr.) 
Hab. Nicaragua, Chontales (Belt*), Los Sabalos (Nutting +), Greytown (LHolland *) ; 
Costa Rica, Tucurriqui (Arcé '). 
Grallaria dives was described from two specimens sent us in 1864 by our collector 
Arcé from Tucurriqui in Eastern Costa Rica!; but it has not, so far as we know, 
until quite recently, been since found in that country, as all subsequent notices 
of it were from Nicaragua, until Mr. Cherrie in writing on Costa Rica birds men- 
tioned and described a young bird from that country® Mr. Holland obtained 
a specimen near Greytown”, and Belt another in the province of Chontales °®. 
More recently Mr. Nutting secured an example at Los Sabalos+, where it was appa- 
rently rare, as the only one seen was observed running along the ground in the thick 
woods. 
The deep russet unstriped flanks, the faint streaks on the breast, the unspotted wing- 
coverts, and the absence of a black rictal stripe on either side of the throat render this 
species easily distinguishable from its two Central-American allies described above. 
We have figured one of the types from Tucurriqui, Costa Rica.

GRALLARICULA. 
Grallaricula, Sclater, P. Z. S. 1858, p. 283; Cat. Birds Brit. Mus. xv. p. 325. 
According to Mr. Sclater there are five species in this genus, one of which, G. Jlavi- 
rostris, occurs within our limits in the State of Panama and in Costa Rica. In general 
appearance Grallaricula resembles some of the small forms of Grallaria, but the tarsi 
are considerably shorter in proportion to the length of the wings, the bill wider at the 
base, the open nostrils are covered by the supranasal feathers, and the vibrisse are 
long—indeed much longer than in any other form of Formicariide. 
The osteology of Grallaricula is not known, hence the position of the genus must 
remain in some doubt. Conopophaga, which has two notches on either side of the 
posterior end of the sternum, is so like Grallaricula in many respects that it may well 
prove that both should belong to the same family, Conopophagide.
