Of this second species of Rhinocrypta (of which a figure is 

 herewith given, Plate VIII.) I obtained a single specimen in 

 1871 from Mr. Weisshaupt, along with a series of birds which 

 he had collected during an excursion from Santiago into the 

 pampas of Mendoza. Not being able to find any published 

 account of it, I wrote to Dr. Philippi, of the Santiago Mu- 

 seum, to know whether it had been described. Unfortunately 

 Dr. Philippics answer did not arrive until after the sheet of 

 the ' Nomenclator ' containing the description of the bird 

 under the name now employed had been printed ofi", or I would 

 gladly have adopted Dr. Philippics MS. appellation, under 

 which I find the bird mentioned in Leybold^s ' Excursion a 

 las Pampas Arjentinas' (8vo, Santiago, 1873, p. 5). 



Besides its uniform colour, -the present species differs from 

 R. lanceolata in its smaller size and the absence of the crest, 

 and the hind claw is shorter and straighter.
