1868.] ON THE AMERICAN RALLID.K. 449 



A single indifferent skin in the British Museum, marked " Lima," 

 is the only specimen we have met with which seems to correspond 

 with Latham's description of this bird ; but we are not sure whether 

 it is really distinct from A. cayennensis.

Several authors have called this bird A. plumbeus, from Vieillot's 

 Gallinula plumbea, which, however, is a Javan species, and has 

 nothing to do with it {cf. Enc. Metli. p. 344). Spix's name sara- 

 cura seems to be the oldest.

This is a very distinct species, easily known by its chestnut head 

 and neck, which are nearly of the same colour as the body beneath. 

 It is clearly the bird described by Cabanis as the adult of his Orty- 

 garchus mangle, and by Leotaud as A. ruficoUis.
