TYRANNIDAi. 
Euscarthmus impiger is described and figured as a new species from Vene- 
zuela, most nearly allied to E. margaritaceiventer (Lafr. & D’Orb.), but dif- 
fering in its olivaceous lower back and the obscure flammulations ” below. 
V. L. Sclater & 0. Salvin, P. Z. S. 1808, p. 171, pi. xiii. fig. 1. 
Leptotriccus superciliaris is a new species from Veragua, diflering from L, 
sylviola of Brazil in its somewhat larger and rather wider bill, and small but 
distinct superciliary streak, beginning above the lore and passing to the back 
of the eye. P. L. Sclater and O. Salvin, P. Z. S. 1808, p. 389, 
An<m'eies cristatellus, Salvad. (Zool. Record, ii. p. 107), is Serpophaga sub^ 
Qristata (Vieill.). P. L. Sclater and 0. Salvin, P. Z. S. 1808, p. 175, note. 
Mionectes oUvaceus is a new species from Costa Rica, difl’ering from 
striaticollis in wanting the dusky colouring of the forehead, crown, cheeks, 
and throat of that species, in having the abdomen of a clearer yellow, in being 
smaller, and having a longer and narrower bill. G. N. Lawrence, Ann. Lyc* 
N. II. New York, 1808, p. 111. 
Elainea. To this genus is referred Pachyrhamphus alhescenSf Gould (Zool. 
* Beagle,’ iii, p. 60, pi. xix.). H. Burmeister, P. Z. S. 1808, pp. 034, 035. 
Suhlegatus is a new genus with the general appearance of Elainea, but with 
the nostrils turned apart, rounded, and entirely open ; otherwise the bill is 
like that of Lcgatus, though more depressed. The gape is beset with a few 
small bristles. Wings somewhat short, the third, fourth, and fifth remiges 
equal and longest j tlie first nearly equal to the nintli, and the second a little 
longer than the sixth. Tail long and nearly even. Tarsi as in Elainea, but 
stouter. The type is 
S. glaher, a new species from Venezuela. P. L. Sclater & O. Salvin, 
P. Z. S. 1808, pp. 171, 172, pi. xiii. fig. 2. 
Rhynchocyclus cerviniventris, Salvad. (Zool. Rec. ii. p. 107), is Contopus 
pallidus (Gosse). P. L. Sclater and 0. Salvin, P. Z. S. 1808, p. 175, note. 
llhynchoeyclus griseimentalis is described as a new species from Costa Rica, 
much like E. olivaceus from Brazil, but more yellowish above, with the breast 
much darker and the middle of the abdomen brighter yellow. It has also a 
larger bill. The points in which it differs from P. brevirostris and P. meso- 
rhynchus (the identity of which two species is suggested) are also pointed 
out. G. N. Lawrence, Ann. Lyc. N. II. New York, 1808, pp. 112, 113. 
Myiobius nationi, Sclat. (Zool. Rec. iii, p. 92), is M, rufcscens, Salvad. 
(Zool. Rec. ii. p. 107). P. L. Sclater & 0. Salvin, P. Z. S. 1808, pp. 174, 
175. 
Empidochanes euleri, E. altirostris, and E. argentinus are new species. The 
first, of which the mode of breeding is described (C. Euler, J. f, 0. 1808, 
p. 184) is from Cantagallo, in Brazil, and much resembles Myiophobus ncevius 
(Bodd.), except that it wants the yellow crown, and in size as well as in co- 
louring is intermediate between that species aiA Muscipeta fvscata, Max {E. 
olivus, Sclat.). The second is from Carthagena, and has the bill somewhat 
broad and higher, with the basal tliird part of the mandible only light 
coloured, the wings and tail longer, and tlie top of the head and rump somewhat 
more olive-coloured, the upper surface being without any reddish-brown ad- 
mixture. The third is from Buenos Ayres, and is smaller, the bill flatter and 
shorter, the mandible whitish, the whole upper surface of a more decided!
