DEFINITIONS

GECINULUS
(Picidae; Ϯ Pale-headed Woodpecker G. grantia) Dim. < genus Gecinus Boie 1831, woodpecker; "Subg. Gecinulus, nobis.  This is a third form of three-toed Woodpecker (in addition to Picoides, Lacep., of northern climates, and Tiga, Kaup, v. Chrysonotus, Sw., of south-eastern Asia and its islands), most nearly allied to Gecinus, from which it differs in the shortness and lateral compression of its beak, and the small size of the feet, which have besides no inner fourth toe. As a peculiar form of Woodpecker, it is very distinct, though represented only (so far as I am at present aware) by P. (Gec.) Grantia, *McClelland and Horsfield, P. Z. S. 1839, p. 165.   ...   *Quære, Grantii, or Granti?" (Blyth 1845); "Gecinulus Blyth, Journ. As. Soc. Bengal, 14, pt. 1, 1845, p. 192. Type, by monotypy, Picus grantia McClelland."
