Show 336 MR. P. L. SCLATER ON CHILIAN BIRDS. [Mai*. 28, p. 26) seems to be only the young of this species, as far as I make it out. Fam. PELECANIDAE. Schlegel unites Pelecanus thagus sive molinee with P. fuscus, and also indicates Pelecanus philippensis as occurring in Chili! (Mus. de P.-B. Pelecani, pp. 28, 35). In the former identification I believe he is wrong. In the latter also I think there must be an error. The question is, are there two species of Pelican found in Chili ? If so, the second is more likely to be P. trachyrhynchus. Dr. Hartlaub gives five species of Cormorants as occurring in Chili. But P. gracilis seems, according to Bonaparte (Consp. ii. p. 173), to be scarcely separable from P. brazilianus; and P. albigula, Brandt, is P. bougainvillii, Lesson. On the other hand we may add P. cirrhatus and P. purpurascens, Brandt, if Bonaparte's localities (Consp. ii. pp. 174, 177) are to be trusted ; and there will thus remain still five Chilian species, besides Graculus elegans of Philippi (Wiegm. Arch. 1850, p. 303), which may possibly be the same as one of the former. Sula variegata of Tschudi, which was referred by Bonaparte, doubtfully, to S. cyanops, is recognized by Pelzeln (Novara-Reise, Aves, p. 157) as a distinct species; but is this view correct? Fam. PROCELLARIIDAE. Messrs. Philippi and Landbeck's Thalassidroma segethi (Wiegm. Arch. 1860, p. 282) seems to be identical with Thalassidroma gracilis, Elliot (Ibis, 1859, p. 391), which name has the priority. Procellaria oceanica, Kuhl, and P. melanogastra, Gould, are also given by Schlegel as having been obtained on the coast of Chili by D'Orbigny. Puffinus carneipes, Gould, and Thalassoica glacialioides (Smith) are also Chilian, on the same authority. I follow Dr. Schlegel also in referring the Halodroma of the western coast of South America to H. garnoti. Fam. LARIDAE. Larus kittlitzii of Bruch is founded on a figure of a bird obtained on the Chilian coast by Kittlitz, and may probably be the same as Larus franklini, which was obtained by Burnett and Fitzroy at Valparaiso, and has been recently redescribed by Messrs. Philippi and Landbeck as Larus cinereocaudatus (Wiegm. Arch. 1861, p. 293). So we may strike L. kittlitzii out of Dr. Hartlaub's list, and in lieu thereof put in Larus modestus, Tsch. (L. bridgesi, Fraser), obtained by Bridges at Valparaiso. Larus scoresbii, Trail (hcematorhynchus, King), occurs in Southern Chili. The only Terns which I can identify positively as occurring on the Chilian coast are:-(1) Sterna cassini, nobis (P. Z. S. 1860, p. 391, = S. antarctica, Peale, nee Less., nee Forst. =S. meridionalis, Cassin, nee Brehm), allied to our S. hirundo and S. macrura; (2) a small species, named in the British Museum "Sterna exilis, Tsch.," of |
