Second List of Birds collected at Conchitas, Argentine Republic, by Mr. William H. Hudson; together with some Notes upon another Collection from the same locality. By P. L. SCLATER, M.A., Ph.D., F.R.S., and O S B E R T SALVIN, M.A., F.Z.S. A second collection of birdskins made by Mr. Hudson having been transmitted to us for inspection by the authorities of the Smithsonian Institution, Washington, we beg leave to offer to the Society a list of the species therein contained which were not enumerated in our former paper on this subject *, with occasional remarks upon them. The collection consists of 105 specimens, referable to fifty different species. The following fourteen were not in the first collection. Two only of these, namely Cyanotis azaree and Elanus leucurus, are not mentioned in Burmeister's work on the zoology of La Plata. 1. TROGLODYTES FURVUS (Gm.) Tr. platensis, Burm. La Plata-Reise, ii. p. 476. Basacaraguay, Azara, Apunt. ii. p. 19. Several examples of this widely diffused species. It has been already pointed out (P. Z. S. 1867, p. 321) that the true Sylvia platensis of Latham (founded on Buffon's Pl. Enl. 730. f. 2) is Burmeister's Cistothorus fasciolatus, which should be called Cistothorus platensis. Azara's Todo voz, Apunt. ii. p. 29. no. 151 (Thryothoruspolyglottus,Vieill.), is, no doubt, the same species. Mr. Hudson gives Ratoncito as the vernacular name of the present bird. * See P. Z. S. 1868, p. 137. |
