lustrations of Ornithology": and of Ort. Douglusii, MontezumcE, and 

 squamalus, which had been characterized by himself in the " Zoolo- 

 gical Journal." In addition to these species he exhibited plates of 

 three others of \vhich lie regretted that he could obtain no spar 

 cimens in London ; namely, of Ort. macrourus, figured by Sir W. 

 Jardiuu and Mr. Selby ; of Ort. SoiininU, figured by M. Temminck 

 in the " Planches Coloriees " [No. 75.] ; and of the Ort. cristatus, 

 figured in the " Planches Enluminees " [No. 126.] of M. Buffon. 

 To these nine described species, he added two others apparently 

 new to science, and which he characterized under the names of Ort. 

 neoxenus ?L\\d affmis ; stating at the same time his doubts whether 

 ])oth might not be the females or young males of the imperfectly 

 known species Ort. Sonni/iii or cristatus. — The following are the 

 specific characteis of these birds. 



V Ortyx neoxenus. Ort. brunneus, supra fusco rufoqxie undulatim 

 variegatus, subtus pallido-rufo maculatus ; gerds lateribusque 

 colli rvfescentibus ; caudd brunneo-fusro rufoque undulatim 

 fasciutd ; crisid bred brunned. 

 Statuia minor quam Ort. calif ornicus . 

 •f Ortyx affinis. Ort. pallide brunneus ; dorso alisque fusco palli- 

 deque rufo variegatis ; caudd pallescenti-brunned, fusco alboque 

 undulatim fasciatd ; capite, collo, pectore, abdomineque rvfescen- 

 tibus, hoc albo guttato, illis alba nigroquc variegatis ; f route 

 apiceque cristte elongatee rufo-brunnecB albescentibus. 

 Statura minor quam species ju'secedens. 



Mr. Vigors proceeded to state, that individuals of four of the 

 above-mentioned species, namely, Ort. virginia/ius, californicus, 

 neoxenus and Montezumce, had been exhibited in a living state in the 

 Gardens of the Society. Specimens of the former three, he added, 

 were still alive there, having braved the severity of the last winter 

 without any artificial warmth. They were all natives of the northern 

 parts of America. The Ort. virgi/iianus, he also mentioned, had 

 bred in this country, and had even become naturalized in Sufiblk. 



He stated in addition, that Capt. P. P. King, R.N., had pointed 

 out to him, amongst his collection lately brought home from the 

 Straits of Magellan, specimens of a bird which he made no doubt 

 was the same as the Caille des Isles Malouines of M. BulFon, figured 

 in the " Planches Enluminees" [No. 222.], and which was subse- 

 quently named Perdix Falklandica by Dr. Latham. This bird has 

 been added to the genus Ortyx by modern authors, but erroneously ; 

 as the structure of the wing, in which consists the chief difference 

 between the Ortyx of America and the genus Colurnix or the Quails 

 of the Old World, associates the Magellanic bird more closely with 

 the latter group than with the birds of its own continent. Mr. 

 Vigors mentioned, that the form which characterizes the true Quails 

 extends to Australia, where several species are found. And referring 

 to the deviation in form, which partially separates the South 

 American bird from the allied groups of the same continent, and 

 brings it in contact with those of Australia, and through them 

 with those of the old continent, he dwelt upon the beautiful series 

 of geographical affinity, which in this instance united the zoology
