lustrations of Ornithology": and of Ort. Douglasii, Montezuma, and 

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

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

 three others of which he regretted that he could obtain no spe- 

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

 Jardine and Mr. Selby ; of Ort. Sonninii, figured by M. Temminck 

 in the " Planches Colorizes" [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 and affinis ; stating at the same time his doubts whether 

 both might not be the females or young males of the imperfectly 

 known species Ort. Sonninii or cristatus. — The following are the 

 specific characters of these birds. 



Ortyx neoxenus. Ort. brunneus, supra fusco rufoque undulatim 

 variegatus, subtus pallido-rufo maculatus ; genis lateribusque 

 colli rufescentibus ; caudd brunneo -fusco rufoque undulatim 

 fasciatd ; cristd brevi brunned. 



Statuia, minor quam Ort. calif ornicus. 



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

 doque rufo variegatis ; caudd pallescenti-brunned, fusco alboque 

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

 tibus, hoc albo gultato, illis albo nigroque variegatis; fronte 

 apiceque cristce elongates rufo-brunnece albescent ibus. 



Statura minor quam species prsecedens. 



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

 above-mentioned species, namely, Ort. virginianus, calif ornicus , 

 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. virginianus, he also mentioned, had 

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



He stated in addition, that Capt. P. P. King, It. 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. Buffon, 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 Coturnix 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
