said not to leave the nest from the time of her entrance till she comes out 
with her young ready for flight, a period of about three months“ (Oates, 
Hume’s Nests & Eggs III, 79). 
GENUS CRANORRHINUS Oalb. Heine. 
The size of an Eagle; bill very large, narrow and decurved, yellow, with 
a transversely ribbed plate at its base, a large and high smooth epithema, in shape 
somewhat like the crest of a Grecian helmet, covering the basal half of the 
culmen and the crown; the nasal aperture round, situated in the crevice formed 
at the junction of the casque with the maxilla, and concealed by bristles; 
throat, cheeks, and periocular skin naked; first primary more than half the 
length of the wing and not greatly attenuated. Sexes dissimilar. The type of 
the genus is C. cassidioc. Three other species included therein by Elliot and 
Grant are aberrant, and a greater uniformity of generic division might be 
obtained by restricting this genus to C. cassidioc.
