ria and Tunisiaand another race in Corsica—through Morocco (V. m.mauritanus), and finally crossing the narrow belt of seato the Canary Islands, where they have again split intotwo races in Gran Canaria and Tenerife. In thisconnection it must be borne in mind that it does notnecessarily follow that the oldest (parent) race isthat of the typical species. The type is, of course,the first of that particular little group of closelyallied races to be described and named by scientists ;it naturally does not follow that this is the root-species from which the other allied forms have sprung.In the case of the Woodpeckers here cited, thereis no evidence to show which of the various racesmentioned is the parent race, though it is fairly obviousthat the bird has spread southwards. We are probablyright in inferring that Dryobates major is of Europeanorigin, and that the Mediterranean, African, andCanarian forms have sprung from the European stock. 1 Rev. gen. des Sciences, November 1912, p. 857.

Canarian Titmice. (To Jace page 126 DISTRIBUTION OF ANIMAL AND BIRD LIFE 127 The Islands possess four closely allied Titmice andthree Chaffinches in addition to the two Blue Chaffinchesalready mentioned. The common Canarian Chaffinch(Fringilla ccelebs canaricnsis) inhabits the islands ofTenerife, Gran Canaria, and Gomera ; while the othertwo islands of the Western Group—Palma and Hierro—each have their own peculiar Chaffinch—F. c. palmceand F. c. ombriosa—the islands of the Eastern Group(those lying nearest Africa) having no Chaffinch livingon them at all. (See Plate facing page 132.) Again, there are four races of Titmouse living inthe Archipelago. On Tenerife, Gran Canaria andGomera, the Tenerife Blue Tit (Pants cczruleustenerlffce) is found ; Hierro and Palma each have theirown forms, P. c. ombriosa and P. c. palmensis, therebyagreeing with the peculiar distribution of the Chaffinches,while a different Pale-coloured race, P. c. degener, lives onthe two large islands in the
