78 REPORT ON ZOOLOGY, MDCCCXLIII. 



GALLINACE^E. 



. Pterocles personatus, Gould, appears in the ' Voyage of 

 the Sulphur; 3 its native locality, however, is not mentioned. (Ann. Nat. Hist, 

 xii, p. 478.) 



GALLING. On the claim of the Rakelhahn (Tetrao me dim] 

 to be considered a distinct species, Wilson lias communicated 

 his observations to the Royal Society of Edinburgh. (Instit. 



p. 298.) 



The Hybrid Grouse occurs here and there in the north of Scotland, but only 

 in those districts where the Capercaillie and Black Grouse are found. In 

 districts where the Capercaillie has been recently introduced, and where the 

 Black Grouse was previously plentiful, the intermediate form did not fail 

 shortly to appear, whence Wilson concludes, that it is not a distinct species, 

 but merely a hybrid. This bird, he says, was formerly unknown in Scot- 

 laud, at least in our time ; it has not been introduced from abroad, and it 

 is at present met with in the same districts wliich are inhabited by the two 

 other species. 



Brandt, in giving a more precise account of Perdix caucasica and altaica, 

 has also furnished the characters of the sub-genera of Perdix. (Bullet, de la 

 Classe Physico-mathem. de 1'Acad. de Petersb. i, p. 278.) 



He receives the genus Perdix in the same sense as Bonaparte, and conse- 

 quently excludes from it Starna, (Perdix cinereci). His arrangement is as 

 follows : 



I. Sub-genus Perdix. Valvulss nasales calvse vel in margine basali ad 

 mediam usque area angusta, subuniscriata, acumiuata pemiularum obsessse. 

 Eemigum prima septima longior, sexta, subsequalis vel brevior. Diffiti et 

 uugucs longiorcs et angustiorcs. Sqwamarum dorsalimn digitos obtegeutium 

 apicalis reliquis sub scqualis. Caitda rectricibus 14-16 composita. 



a. Gymnorrhines (Lerwa, Hodgs.). Falvulce nasales calvse ; hypochondriorum 

 penua? acumiuatse vel sub acumiuata;. To this division belong Perdix Heyi, 

 Temm., P. yri&eogularis, Brandt, and other species. 



/3. Pterorrhines (Chacura, H.). Valvulce uasales area angusta uuiseriata 

 penuarum ad medium usque extensa vestitse ; hypochondr. pcnna; in adultis, 

 dilatatse, truncato-rotundatse. To this belong, Perdix r/raica (saxatilis), 

 P. rubra, P. petrosa, P. melanocephala, Riipp. and others. 



II. Sub-genus. Hegaloperdir, Brandt, (Tetraogallus, Gray, Chmirtka, Mot- 

 choulski). Faloulte nasales basi tota? areola arcuata angusta pcuuularum 

 pluriseriatarum obsessse. Remigum prima sexta longior. Diffiti et ungues 

 breviores ct latiorcs. Plants latiores. Squama ruin dorsalium digitos obte-
