Ohs. Rhinocryptee species secunda, colore unicolori prorsus 
notabilis. 
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 f Nomenclator 3 containing the description of the bird 
under the name now employed had been printed off, or I would 
gladly have adopted Dr. Philippics MS. appellation, under 
which I find the bird mentioned in LeyboldCs f Excursion a 
las Pampas ArjentinasC (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. 
Genus 4. Lxosceles. 
Liosceles, Scl. P. Z. S. 1864, p. 609. 
Upon reconsideration I think that this singular form, for 
which I have already suggested a subgeneric appellation, can¬ 
not be properly associated with Pteroptochus. Besides the
