434 CLASS xvi. 



PI. 153; West of Asia, South of Europe, especially Spain, met with also 

 occasionally in Germany. These two species are the largest of this genus, 

 of the size of a partridge ; the remaining are of the size of a turtle-dove, 

 and are almost all found in Africa. This genus forms in many respects 

 the transition from the grouse to the dove-tribe. 



Syrrhaptes ILLIG., Nematura FiSGH. Bill small, conical. 

 Nostrils concealed by feathers. Tarsi hirsute on all sides; toes 

 short, concrete, hirsute above; hallux none. Two middle tail- 

 feathers and first two quills of wings produced into setaceous, 

 pointed filaments.

 II. Tab. **, p. 73 (this plate is inscribed Tetrao arenaria by mistake), 

 TEMM. PL col. 95, GRAY Gen. of Birds, PL cxxxiv. ; lives in the Steppes 

 of Tartary ; compare LICHTENSTEIN in EVERSMANN'S Reise von Orenlerg 

 nock Buchara, Berlin, 1823, s. 13 f 136. 



Family XVIII. Thinocorince. Bill short, conical, compressed 

 at the sides. Nostrils lateral, placed in a pit of bill, concealed by 

 membrane beset with plumules. Tarsi denuded, scutellate or reticu- 

 late with scales. Anterior toes joined at the base by a small mem- 

 brane; hallux small, raised. Wings pointed, with first quill longest 

 of all. 



Attagis ISID. GEOFFR. and LESS. Bill slender, with lower 

 mandible shorter, narrower. Tarsi short, strong, reticulate with 

 scales. Tail rounded, short, ample. (Eyes somewhat remote from 

 the base of bill.) 



Sp. Attagis Gayi ISID. GEOFF, and LESS. Centurie Zool. PL 47; Attagis 

 Latreittii LESSON, Illuslr. de Zool. PL 2; Attagis Falcklandka, Perdix 

 FalcTclandica LATH., BUFF. PI. enl. 222. Birds from South America and 

 the Falkland Islands, somewhat smaller than partridges, which have much 

 affinity with CMonis, and, like the species of the following genus, form the 

 transition to the Grallatores. The tarsi covered with hexagonal scales 

 distinguish the genus Attagis from the rest of the gallinaceous birds. 



Thinocorus 1 EsCHSCH. (Tinocorus LESS.). Bill short, strong. 

 Tibiae denuded above the heel. Tarsi covered on the anterior 

 surface with a single row of transverse scutes. Tail short, rounded. 



1 From 6iv, 6iv6s the shore, and Kbpvs a lark, and not from xopetfw, as we read in 

 AGASSIZ Nomenclator zoologicm; a work which, as far as relates to the etymology of 

 names, deserves little reliance.
