The preceding characters are drawn up from a specimen be- 

 longing to Mr. Wallace. Others are in the British and Munich 

 Museums ; but I do not consider this a common bird in collec- 

 tions, and though I possess examples of twenty-one out of the 

 thirty-three species described in this Synopsis, the pi-esent is 

 one of those that I have never been fortunate enough to meet 

 with except as before mentioned. 



It is difficult to ascertain the true date of the publication of 

 the diiFerent feuilletons of Temminck's ' Planches Coloriees,' but 

 I believe Spix's name for this species was the first published, as 

 is generally allowed to have been the case. 



The name Nonnula — proposed for the subdivision of the pre- 

 sent genus which contains this and the next two succeeding 

 species, in a communication upon new BucconicUe made to the 

 Zoological Society last December — I coined as a diminutive of 

 Nonna, i. e. Monaca, the word, I suppose, intended by V^ieillot 

 when he established the genus Monasa. 



11. Malacoptila. frontalis, Sclater. 



M. cinerascenti-brunnea : pectore brunneo-rufescente, quasi fere 

 ferrugineo ; ventre albescente : capite summo antice castaneo : 

 rostro nigro, mandibula iuferiore basi flavescente. 



Long, tota 5-5 ; alse 2*5 ; caudse 2'3. 



Hab. in Nova Grenada. 



The British Museum contains two specimens of this appa- 

 rently new Malacoptila, selected amongst other interesting novel- 

 ties from a collection lately received by Mr. S. Stevens from 

 Santa Fe di Bogota. I have to thank Mr. G. R. Gray for allow- 

 ing me to examine them. 



The species is most closely allied to the preceding, and inter- 

 mediate between that and the succeeding M. nificapiUa. It may
