122 NILS GYLDENSTOLPE, ZOOLOGICAL RESULTS OF THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 
My specimens, which both are males, are a little larger than specimens from India 
and Hainan, having their wings measuring 86 & 87 mm., respectively, while in the Hainan 
birds the wings measure 82—84 mm. (4 males measured by HarTERT). 
On the tails there are 6 ochraceous bars (the one at the tip not counted).

The Large Barred Owlet is the Owl most often met with in every part of Siam. It 
occurs as well in dense evergreen jungles as in open deciduous forests and was found 
as far south as about Lat. N. 12°. However, it was a little more rare in the Siamese Ma- 
laya than in the Northern Provinces. 
Like other members of this family the Large Barred Owlet is a very variable species 
as to size and colour. The number of the white tail-bars seems to be rather constant in the 
birds collected in Siam, being always five, the basal bar and that one at the tip not counted. 
I have compared my Siamese specimens with two birds collected at Ahsown in 
Tenasserim and they are absolutely identical as to size and colour, but the Tenasserim 
birds have six tail-bars, the basal one and that one at the tip not counted. Some specimens 
have these bars broader, some narrower. 
Two specimens from Doi Par Sakeng and Ban Meh Na in Northwestern Siam have 
very obsolete bars on the back, the rufous colouring being almost confined to irregular 
spots. Some of the feathers of the hind nape have large subterminal white spots almost 
forming an incomplete collar. The general colouring of these two specimens is distinctly 
more rufous, hence approaching the birds from Hainan which have been separated under 
the name of G. c. persimile, HARTERT.

A fine female specimen of this rare Owl which has not previously been recorded from 
Siam, was shot by my Dyak collector in a dense valley among the Koon Tan mountains.
