passage both out and back ; in the latter case, however, only females ami 

 young. Some remain, according to him, even up to the time of breeding. 



Ftilro arcadicus, proposed as a new species by Lindermayer, and figured 

 in pi. 1, appears, however, as he himself supposes, to be nothing else than the 

 younger condition of F. concolor, Tenim., or F. Eleonorte, Gene, both which 

 latter have great mutual resemblance, but are as yet too little known to allow 

 of their specific identity being declared with certainty. 



As Greek Accipitres, Count v. Miihle adduces the following six species : 

 Falco Halieet/ts, Bonclli, laniarius, pennatus, melanopterus, and parasiticas, 

 which are not mentioned by Lindermayer, 



Extra European species, either newly established, or at least newly de- 

 scribed, are : Falco subiiit/er, locality unknown, F. yuttatm, and Ast/tr cris- 

 tatus ; both the latter from the Philippines. (Gray, Annals, xi, p. 371.) 

 Hitluelits unicolor, Gray, appears, according to Brandt, to be identical with 

 Falco leucoryplius, Lath. (Annals, xi, p. 113.) Haliastur leucostenms, Gould, 

 and Haliastur ? (Milrits) sphenunts, Vieill., have been figured by Gould in 

 his 'Birds of Australia' (part 11). (Ib.) Astur Novce Hollandiee, Lath., in the 

 gray as well as in the white albino plumage (part 12). Tinnunculus cencroides, 

 Vig., Circus assimilis, Jard., and C. Jardinii, Gould (part 10). Pane/ion 

 leucocephalus, Gould (part 13). New species instituted by Gould are, Astm* 

 critcntussm&.Elamis scriptKS; both from Australia. (Ami. xi, pp. 528, 401). 



Polyboroides (uomina geuerica in "oides" desineutia e foro releganda 

 sunt. Philos. Bot. 216.) typicus, Smith (Falco gymnogenys, Temra.,) is 

 figured and described in detail, in both the old and young condition, by A. 

 Smith in his 'Illustrations of the Zool. of S. Africa,' pi. 81, 82. 



A review of the general relations of the Owls has been 

 given by Gerard in the Diet, Univ. d'Hist. Nat. iii, p. 631, 

 under the article ' Cliouette.' 



This is one of the best of the ornithological articles contained in the present 

 part. Gerard correctly regards the received divisions merely as subgcuera ; 

 he does not enter upon the species. Since, in a dictionary, the articles are, 

 easily found; and, as in the present instance, most of them do not cuter spe- 

 cially into detail, the Reporter will, usually, not cite them separately. 



With respect to the summer habitat of Strix 5ra<?//yo^,Mallierbe entertains 

 an opinion very different from that of Lindermayer, Count v. Muhlc, and 

 Drummond. According to the latter it is never seen in Greece and in Corfu 

 during the summer, but only on its passage, and in the winter; according to 

 Malherbe, on the contrary, it is very common in summer in the mountain 

 forests of Sicily, which is owing to the greater elevation. It is remarkable 

 that Strix Tengmalmi (dasypus), according to Liudermayer, reaches as far as 

 Greece ; he terms this species " very rare, and only in olive woods." 



Guerin-Meneville has described two Abyssinian Owls, under the names of 

 Bubo cinerascens and Otus abys&inicus. (Rev. Zool., p. 321.)
