as in the Cape Verde Islands, while P. obscurus breeds ia the 

 Bermudas and the Antilles. Both species have a wide range. 



Mr. F. W. Styan sent for exhibition a new Woodpecker 

 from Fohkien, which he proposed to call — 



Chrysophlegma ricketti, sp. u. 



Adult male. Most nearly allied to Chrysophlegma pierii, 

 but different from that and other allied species in having the 

 primaries coarsely barred with chestnut and black to the 

 extremity ; the chin, moreover, being rufous streaked with 

 black, and only the malar region white with a faint yellowish 

 tinge. 



Hab. Ching Ting, Fohkien. 



Mr. ScLATER brought forward the subject of " Bipolarity," 

 which had been much discussed recently in the debates on 

 the question of the scientific advantages of an Antarctic 

 expedition, and remarked that in the case of the higher 

 Vertebrates, or in that of Birds at least, no sort of -^^ Bi- 

 polarity " could be stated to exist, whatever might be the case 

 in the lower marine animals. Mr. Sclater exhibited a list 

 (see p. 430) in which the birds of Arctica, as represented by 

 the known birds of Franz Josef Land {cf. Ibis, 1898, p. 249), 

 were contrasted in parallel columns with those of Antarctica 

 {cf. Ibis, 1894, p. 494), and pointed out that not only were 

 all the Species different, but nearly all the Genera and most 

 of the Families and Orders. Three species of Passeres were 

 found in Arctica, whereas not one was known from Ant- 

 arctica, although there were vague rumours about a Corvus 

 having been seen there. An Owl and a Hawk were found 

 in Arctica, but no Accipitres had yet been met with in 

 Antarctica. At least two species of Anseres were found in 

 Arctica, but there were only uncertain reports of a Goose of 

 some kind in Antarctica. Three species of Tringoid Limicolcs 

 occurred in Arctica, whereas in Antarctica only the Sheath- 

 bill {Chionis), belonging to a peculiar Antarctic Family, was 

 known. Among the Gavia the correspondence was better, 

 as the genera Sterna, Larus, and Slercorai'ius were repre-
