IH83.] BIRDS OF THE ARGENTINE REPUBLIC. 43 



31. PoDiCEPS CALiPAR^us (Lesson). 



c? . Cosquin, Cordova, Arg. Rep., Sept. 6, 1882. 

 Iris crimson. 



This was the only specimen seen, and obtained in the same locality 

 as P. rollandi. 



32. PODICEPS ROLLANDI (Q. Ct G.). 



c?. Cosqviin, Cordova, Arg. Rep., Sept. 11, 1882. 



? . „ „ „ Sept. 1, 1882. 



Iris crimson. 



These were obtained on the river ; but I never obseiTcd any more. 



33. NoTHURA ciNERASCENs, Burm. 



Cosquin, Cordova, Arg. Rep., Aug. 21, 1882. 



Iris amber. 



This species is met with on the thickly wooded slopes near the 

 mountains, where the shrubs branch out quite low down, barely 

 leaving room for the ingress and egress of the bird beneath. They 

 are not common, and I only observed them singly. A slight rustling 

 among the leaves alone indicates their presence ; and if you are quick- 

 sighted, you may get a glimpse of them as they start out two or 

 three yards from cover. Once in the open, they stop abruptly an 

 instant to plume their wings, and off they are over the trees with a 

 flight neither long nor quick but very jerky ; I found them, however, 

 very difficult to shoot, on account of the density of arboreal growth. 



[Besides the species mentioned in Mr. White's notes above given, 

 Mr. White's collection, received by Mr. E. Gerrard, juu., contains 

 several examples of a fine new Finch of the genus Poospiza named by 

 Mr. White P. erythrophrys, but decidedly different, as I find ou 

 comparison with the type of the latter species in ray collection. 

 This I propose to dedicate to its discoverer as 



Poospiza whitii, sp. nov. (Plate IX.) 



Supra cinerea ; capitis lateribiis nigris, supra stiperciliis longis, 

 infra strigis rictalibus albis marginatis ; subtlis saturate fulvo- 

 castanea, ventre medio et imo albo, crissofulvescente ; subalaribus 

 et campterio alari albis ; caudd plumbescenti-nigra ; rectricibus 

 lateralibus externis lati, duabus proximis angnstius albo termi- 

 nal is ; rostro nigro, pedibiisfuscescenti-carneis: long, tola o'o, 

 alee 2'4, caudce 2-(i poll. Angl. Fem. mari similis, sed supra 

 fuscescenfi-cinerea, et subiits colore pectoris et laterum brunneo 

 diver sa. 



Hub. piope Cordova rep. Arg. (E. W. White). 



Obs. Sp. P. nigrorufce proxima, sed colore pectoris saturate 

 badio, neque rufo, facile dignoscenda. 



Mr. White's examples of this pretty species were obtained at 

 Cosquin in June, July, and August last. The iris is noted as 

 " dark brown."]
