10. TlIAMNOPHILUS LUCTUOSUS, Licht. 



Lanius luctuosus, Licht. Verz. d. Doubl., p. 47. 

 Thamnophilus luctuosus, Tsch. F. P., p. 172 ; Gray's Gen., i. 



p. 297; Bp. Consp., 298 (excl. synon.) Th. melas, Cuv., in 



Mus. Paris. 



$ niger cristatus, tectricibus alarum minoribus, superioribus, 

 inferioribus et cauda apice albis. 



$ aut juv. cinerascentior et crista rubra. 



Long, tota 6*7, alae 3*2, caudse 2*5. 



Hab. Para (Licht.) ; Eastern wood region of Peru, between 

 12°. and 14°. S. lat. (Tsch.) 



I have seen specimens of this bird in the Berlin, British 

 and Paris museums. It has been confounded by some authors 

 with T. severus, from which it is, however, quite distinct. 



11. Thamnophilus corvinus, Gould. 



$ ater ; axillis summis niveis ; rostro producto valido. 



Long, tota 7*5, alae 35, caudae 2-7. 



Hab. Eastern Peru, Eiv. Ucayali (Gould.) 



The only example I have seen of this bird is in Mr Gould's 

 collection from the Ucayali. It was obtained in June 1852, 

 and is marked " male, irides brown." Lafresnaye's Th. im- 

 maculatus agrees with the present species in general colour- 

 ing, but is of much slighter form, and has a weaker bill. 



12, Thamnophilus fuliginosus, Gould. 

 Thamnophilus fuliginosus, Gould, Pr. Z. S., 1837, p. 80 ; 



Gray's Gen., i. p. 298. 



$ cinereus ; gutture et capite cristato nigris ; cauda obso- 

 lete trans-faciata ; rostro nigro, valido, adunco. 



Long. 7*5, alee 3*5, caudae 3 # 0. 



$ summo capite, dorso alisque castaneo-fuscis ; loris linea 

 super oculos, plumis auricularibus, colli lateribus, gutture, cor- 

 pore subtus et cauda intense cineraceo-coeruleis ; plumis singu- 

 lis lineis cinerascenti-albis fasciatis ; pogoniis internis rectri- 

 cum albis lineis fasciatis ; rostro pedibusque nigro-brunneis. 



Hab. British Guiana. 



I have seen but one specimen of this bird, a male, in the 

 Derby Museum at Liverpool. I have therefore taken Mr 

 Gould's characters for the female.
