t Ihiyau cola extrana, Azara, Apunt. no. 315 (1805), and Caprimulgus 

 enicunts, Vieill. Enc. Meth. p. C43 (1823) (based on Azara), probably refers 

 to some Hydropsalis, but I am unable to say to which species. 



Caprimulgus manurus, Vieill. Kouv. Diet. x. p. 239, and Enc. Meth. p. 540, 

 is also a species of this genus, but it is doubtful to which species it belongs. 



There are also two other Goatsuckers described by Azara in the 'Apunta- 

 mientos ' which remain unidentified: — the Ihiyan anonimo, on which Caprim. 

 sphenurus, Vieill. Nouv. Diet. x. p. 243, is based ; and the Ihiyau acanelado.
