considered the CRANES and RalIts the typical forms. Whether the 
BusTARDS and SERIEMA should be also added seemed questionable ; 
but the former connect it with the CHARADRIOMORPH& and the 
latter with the AETOMORPHA. 
GERFALCON, see GYRFALCON. 
GERYGONE, Gould’s name, now used as English, for a genus 
of uncertain position, generally placed among the Muscicapidx 
(FLYCATCHER), but shewing great resemblance to some Sylviidx 
(WARBLER), and especially to the Hypolais-group. Six species were 
recognized by him as inhabiting Australia, and nearly two dozen 
more, from the -Philippines, Borneo, New Guinea, Norfolk Island, 
New Zealand, and other islands, have been referred to this genus, 
most of which Dr. Sharpe has since separated (Notes Leyd. Mus. 
1879, p. 29) under the name of Pseudogerygone. The Australian 
and New-Zealand forms are inconspicuous little birds, building a 
pensile domed nest, and are among the commonest foster-parents of 
the Cuckows of their respective countries (cf. North, Descr. Cat. 
Nests & Eggs of B. Austral. pp. 97-100; Buller, B. New Zeal. ed. 2, 
i. pp. 45-48). 
GIER-EAGLE (Dutch Geter, Vulture), the rendering by English 
translators of the Bible of the Hebrew Racham (Levit. xi. 18; 
Deut. xiv. 17), said by Canon Tristram to be the equivalent of the 
Arabic Rachmah, the vernacular name of the Egyptian VULTURE, 
Nephron percnopterus. 
GILLY-HOWLET, a Scottish nickname for the Barn-OWL, 
Aluco flammeus, “Gilly” being an abbreviation of Gillian ( = Juliana), 
comparable with Jack-DAw, Mag-Pin, Robin-REDBREAST, Tom-TIr, 
and others. 
GLASOOGJE (= Glass-eye), the name given by the inhabitants 
of the Cape Colony to the common species of ZOSTEROPS, Z. capensis, 
found in that country (Layard, B. S. Afr. p. 116); but the 
GLASS-EYE of Jamaica is a TuHrusH, 7'urdus jamaicensis (see 
Gosse, B. Jamaica, p. 142). In the. former case the name is given 
from the ring of white feathers surrounding the eye, in the latter 
from the colour of the iris. 
GLEAD or GLED (AS. Glida; Sw. Glada), an old English 
name not wholly obsolete for the Kire, referring to its gliding 
flight. 
GNAT, the same as Knor,! according to Sir Thomas Browne 
1 Tn this connexion Mr. Charles Swainson (Prov. Names Br. B. p. 194) un- 
happily quotes the line 
“The little Gnat-snap, worthy princes’ boords,” 
to be found in the translation by Josuah Sylvester, who died in 1618 ( Works, ed.
