1867.] MR. p. L.. SCLATER ON CHILIAN BIRDS. 323 



(ii. p. 181), gives this bird as Chilian under ihe name C. atratu, as 

 he has himself stated (Pr. Acad. Phil. 1865, p. 91) ; and examples 

 transmitted from Chili by Mr. Leybold of Santiago bear the same 

 name upon them. 



Of Sycalis, a genus closely allied to the African Canaries (Cri- 

 thagra), there are likewise two distinct species found in Chili, of 

 both of which I have received examples from Mr. Landbeck. The 

 larger of these is the Sycalis aureiventris, Ph. et Landb. (Arch. f. 

 Nat. 1864, p. 49), allied certainly to S. luteocephala (Lafr. et 

 D'Orb.) of Peru and Bolivia, as its describers justly observe, but 

 apparently well distinguished by the want of any yellow edgings to 

 the remiges and rectrices, and not, as far as I am aware, previously 

 described. The second is the Sycalis arvensis of my American 

 Catalogue {Fringilla arvensis, KittlitzJ. The examples of this spe- 

 cies forwarded by Messrs. Philij)pi and Landbeck are labelled " Gri- 

 thagra bi-evirostris, Gould " — a name which apparently belongs to 

 a different species of the same genus. 



Fam. IcTERiD^. 



Agelasticus thilius (Cab. Mus. Hein. i. p. 188) is a common 

 Chilian bird, and figured in Gay's 'Historia' under two names — 

 Cacicus chrysocarpus and Xanthornus cayennensis ! (Cf. Philippi, 

 Wiegm. Arch. 1855, p. 13). The female or young bird is brown 

 striated with black, as in Agelceus, from which this form is hardly 

 distinguishable generically. 



Sturnella militaris and Curceiis aterrimus are two other well- 

 known species, both belonging to this group. The former is widely 

 diffused over the extreme of South America and the Falkland 

 Islands ; the latter I have only seen from Chili. 



Fam. Dendrocolaptid.e. 



Of the genus Geositta I have met with three Chilian species, 

 namely : — 



1. G. cunicularia (Vieill.) ; Certhilaiida cnnicularia. Ph. et 

 Landb. (/. c. 1865, p. 59). *' Found in the provinces of Colchagua, 

 Santiago, and Aconcagua, on the Subandean plains and sea- coast 

 region." The examples of this species forwarded by Messrs. Phi- 

 lippi and Landbeck are quite identical with those previously in my 

 collection, and thus named (Cat. Am. B. p. 146). 



2. G. isabellina ; Certhilauda isahellina. Ph. et Landb. /. c. 

 p. 63. Of this fine species Messrs. Phihppi and Landbeck have 

 transmitted me examples of both sexes. It was not previously 

 known to me. 



3. G. fasciata ; Geobamon fasciata, Ph. et Landb. I. c. p. 68. 

 Messrs. Philippi and Landbeck have likewise sent me two exam- 

 ples of this species, of which I had previouslj^ an indifferent speci- 

 men in my collection, purchased of Parzudaki in 1854. This I had 

 referred doubtfully (and probably erroneously) to G. maritiina, 

 Lafr. et D'Orb. ; but I shall now adopt the name given by Messrs.
