GYMNOLDMUS. 351 
we have ever heard. It begins with a series of notes precisely like the 
‘song’ of a common hen magnified about fifty-fold, and ends with an 
indescribable combination of cackles and shrieks.

ures: Length, about 710; wing, 290; tail, 240; bill from nostril, 111; 
greatest length of crest, 106; tarsus, 52. 
“Adult female-—Resembles the male, but the casque is less developed 
and the size smaller. Length, 610; wing, 264; tail, 216; tarsus, 53.” 
(Grant.) 
“We saw this bird on several occasions in Palawan, but always in 
very high trees, and it was so extremely wild that we did not succeed in 
securing any specimens from that island. In the Calamianes Islands 
we found it both common and tame. On several occasions we saw it 
feeding in low fruit trees within a few feet of the ground.

of lower mandible; bare skin of head white. A female measures, 610 in 
length; wing, 263; tail, 204; tarsus, 46; middle toe with claw, 58.”
