PICIN^. GECINUS.

similar to those of the last species. It usually prefers the 
higher branches of trees, although it by no means confines 
itself to them, and is so intent on searching for its food that 
it pays little attention to a person coming to watch or shoot 
it. It produces an extraordinarily loud, rapid, vibratory noise, 
somewhat resembling that made by the boring of a large auger 
in hard wood, but its ordinary voice is a feeble squeak, seve- 
ral times repeated. The eggs, five in number, and white, are 
laid in the bottom of a hole formed in decayed wood.

GENUS LXXIY. GECINUS. GREEN- WOOD- 
PECKER. 
The common Green- Woodpecker and a few nearly allied 
species may be separated from the rest to constitute a genus, 
to which Boie has given the name of Gecinus. This genus 
makes some approximation to Colaptes, or that of the Golden- 
winged Woodpeckers of America, and is remarkable espe- 
cially for having the two glosso-laryngeal muscles twisted 
round the trachea, which I have not found to be the case in 
any of the other fifteen or twenty species which I have dis- 
sected, with the exception of Colaptes auratus. 
Bill rather long, somewhat slender, angular, straight, 
tapering, laterally bevelled at the tip, so as to present an 
edged, abrupt, wedgelike termination ; upper mandible with 
the dorsal line slightly convex, the ridge sharp, the sides 
with a longitudinal elevated line close upon the ridge, the 
tip slender, and slightly truncate. Mouth narrow ; tongue 
vermiform, terminated by a narrow, flat, horny point, fringed 
with reversed bristles ; the other characters, as in Picus. 
144. Gecinus viridis. Crimson-headed Green-Wood- 
pecker. 
Male with the upper parts yellowish-greeu, the rump green- 
ish-yellow ; the upper part of the head and hind neck crimson, 
the loral and orbital spaces, and a mystachial band, black, the 
latter with a crimson patch ; the lower parts pale greenish-
