Mr. P. L. Sclater on the Fissirostral family Buccoiiidsc. 477 



In the curiously produced feathers descending from each 

 extremity of the lower mandible, this species agrees with the 

 three following, and they are also all four closely allied in plumage.

I found this new species among the birds of this family in the 

 British Museum, which I have had full opportunity of examining 

 through the kindness of Mr. G. R. Gray. In the upper plumage 

 it closely resembles M. mystacalis, but the spots are rather 

 smaller and more generally distributed than in that species. The 

 front is fuliginous, the lores whitish. The under surface comes 

 nearer to M. suhstriata, but the throat and mental bristles are 

 here quite white and not ferruginous, and the spots are not so 

 dark. The bill resembles in colour that of M, mystacalis, but is 

 more slender in form.

 Monasa mysticalis, Lafr. Rev. de Zool. 1850, p. 215. pi. 3. 

 M. fuliginoso-brunnea; dorsi medii et tectricum alariura plumis 

 macula triangulari pallide fulva ad apicem notatis : fronte 

 loris et plumis mystacalibus albis : gula media et pectore toto 

 ferrugineo-rubro ; ventre medio albicante; lateribus obsolete 

 fulvo striatis : rostro nigro, mandibula inferiore basi flavo ; 

 pedibus pallidis. 

 Long, tola 7*4 ; alse 4*0 ; caudse 3*5.

This and the two preceding and next following species are re- 

 markable for the great development of the rictal bristles and the 

 quasi moustachios descending from each side of the chin, whence 

 M. de Lafresnaye formed his name for this bird. The present 

 species may be distinguished from the two preceding by the deep 

 red- brown throat and breast. Two examples in my possession 

 came, as M, de Lafresnaye's, from Santa Fe di Bogota.
