2 imm. Rimbo Pengadang, Lebong, Bencoolen,

pale yellow.

115. Cuculus optatus Gould.

Iris yellow, upper mandible horn black, slightly 
yellowish at the base, lower mandible greenish yellow, tip 
and tomia black, bill internally orange, feet pale orange 
yellow. 
Wing 190 mm. 
Though very like C. canorus this specimen is too small 
to be C. c. telephonus, Heine, which also occurs in Malaysia 
(wings 208-240 mm.). Dr. Hartert has examined the skin 
and confirms our determination. Evidently a rare bird in 
Malaysia as we have seen only one other example—a male 
from Koh Lak, S. W. Siam obtained in April (wing 
198 mm.).
