Birds of Celebes: Muscicapidae. 
“We heard the bird singing on the topmost point of Lompobatang, on the tall- 
est tree in South Celebes. The song is very melodious”. It and S. septentrio- 
nulis are evidently only geographical races. 
GENUS HYPOTHYMIS Boie. 
The Blue Flycatchers may be distinguished from all the foregoing by their 
having the tail as long as the wings; the wing is more rounded, the second 
primary shorter than the secondaries, which are about Vs the length of the 
wing, the 4“*, S*’' and 6*'“ primaries the longest. The bill is moderately large, 
the culmen from the frontal suture almost as long as the cranium ; the rictal 
bristles large and strong, the longest reaching nearly as far as the tip of the 
bill. The genus is found from the Himalayas as far as the Philippines, Celebes, 
Sula, and the Lesser Sunda Islands.
