580 MR. 0. SALVIN ON NEW BIRDS FROM Costa RICA. [Nov. 8, 
1. CaATHARUS GRACILIROSTRIS, Sp. nN. 
C. supra dorso, uropygio, alis et cauda extus cinnamomeo-brunneis 
concoloribus ; pectore etiam concolore, sed pallidiore : capite 
toto cum gula cinereis, pileo obscuriore: ventre et corporis la- 
teribus cinereis, illo medialiter albidiore, crisso brunnescentiore : 
alis intus et rectricibus fuscis : rostro nigerrimo, pedibus pallide 
Suscis. 
Long. tota 5°6 poll., alee 3-1, caudz 2-7, tarsi 1°2, rostriarictu*75. 
Hab. Costa Rica (Volcan de Cartago). 
Affinis C. franizii, Cab., eadem ex patria, sed gula et pileo cine- 
reis facile dignoscendus. 
A well-marked species, making the sixth inhabiting Central 
America. 
2. THRYOTHORUS ATROGULARIS, Sp. Nn. 
T. castaneus : pectore, gula et capitis lateribus nigris, his cum su- 
perciliis obscure albo maculatis : alis et cauda fuscis, illis extus 
castaneis, hac aliquando septem fasciis pallidis cancellata ; tec- 
tricibus subcaudalibus et cumpterio nigris, albido transfasciatis : 
rostro et pedibus nigris. 
Long. tota 5°3, alee 2°9, caudee 2°4, tarsi 1 ; rostri a rictu °85. 
Hab. Costa Rica (Tucurrique). 
In having the Wren-like markings of the ear-coverts and bands of 
the tail almost (in some specimens entirely), and the cross markings 
of the wings quite obsolete, this species resembles 7. coraya (Buff. 
Pl. Enl. 701. f. 1); but there the likeness ends, the long strong 
bill of the present bird and its black throat rendering it easily dis- 
tinguishable. Its place appears to be with 7. coraya in the group 
Pheugopedius, Sclater. 
3. THRYOTHORUS THORACICUS, Sp. 0. 
T. supra cinnamomeo-brunneus, pileo cinerascentiore, uropygio 
rufescentiore: capitis collique lateribus cum gula et pectore 
albis, plumis undique nigro marginatis: alis extus, cauda et 
crisso brunneis, nigro transfasciatis : ventre brunneo, lateribus 
rufescentioribus : rostro plumbeo, mandibule inferioris basi 
albida. 
Long. tota 4°6, alee 2°4, caudz 1°7, tarsi ‘8; rostri a rictu °85. 
flab. Costa Rica (Tucurrique). 
This Wren is unlike any member of the genus with which I am 
acquainted. At first sight it appears to resemble 7’. maculipectus, 
Lafr. (Rev. Zool. 1845, p. 338), but differs most essentially from that 
species, not only in having barred wings, but in the distinct charac- 
ter of the chest- and throat-markings ; the bill too is much stronger. . 
Its place, however, seems to be in the neighbourhood of that species, 
and near J’. pleurostictus, Sclater (Ibis, il. p. 30), in the group 
Pheugopedius, Scl. (vide Baird’s Review of American Birds, p. 121). 
4. My1apEesTES MELANOPS, sp.n. (Pl. XXXV.) 
M. schistaceus unicolor, subtus dilutior : fronte, loris, ciliis et mento
