120 NILS GYLDENSTOLPE, ZOOLOGICAL RESULTS OF THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 
Fam. Bubonide. 
240. Ketupa zeylonensis zeylonensis. Gm. — The Brown Fish-Owl. 
Ketupa ceylonensis: Robinson & Kloss p. 30; Robinson I p. 90. 
Ketupa zeylonensis: Gyldenstolpe III p. 233. 
1 ad. Koon Tan April 1914. W = 375 mm.; T = 192 mm.; C = 31 mm.; Tarsus = 73 mm. 
Fairly rare in the parts of the country visited by the Expedition though probably 
generally distributed in well-wooded tracts near rivers and creeks at least in Northern 
and Central Siam. 
Only one specimen was shot — at Koon Tan — and a few more were observed at 
this same place and in the neighbouring country. 
Outside Siamese Territory this species has been found in British India, Ceylon, 
Southern China, Hainan and Cochin China. In the Malay Peninsula it seems to be very 
rare though some specimens have been lately recorded from Trang. 
241. Huhua nipalensis. Hopes. — The Forest Eagle-Owl. 
Huhua nepalensis: Gairdner p. 150. 
9 (?) Koon Tan 1914. W = 420 mm.; T = 238 mm.; C = 86 mm. 
A fine specimen of the Forest Kagle-Owl was caught in a trap at Koon Tan by one 
of the Railway Engineers who kindly presented it to me. »One afternoon», he told me, 
ya large owl was trying to catch a chicken but was frightened away before it had carried 
of its prey. A trap was now brought and the dead chicken placed as a bait. About an 
hour afterwards the Eagle-Owl returned and was caught. » 
This beautiful species seems to be very rare and besides the specimen obtained I 
only saw one more, also among the Koon Tan Hills, but I unfortunately missed it. Both 
these specimens occurred in a mixed pine and oak-forest at a fairly high altitude. 
GAIRDNER has recently recorded this species from the Ratburi and Petchaburi 
Districts of Southern Siam. 
242. Otus bakkamoena lettia. Hopas. — The Collared Scops Owl. 
3 Pak Koh */3 1914. L = 195 mm; W = 158 mm.; T = 88 mm.; C = 15 mm. — @ Chum Poo 
3/5 1914. L = 220 mm.; W = 167 mm.; T = 93 mm.; C = 17 mm. — ¢ juv. Koon Tan °%/1 1914. L = 
160 mm.; W = 117 mm. — Irides: brown (black in young). Bill: horn colour or yellowish green. Legs: 
light brown. 
In the most northern parts of Siam the Collared Scops Owl was not uncommon, 
though on account of its nocturnal habits and its shyness it is seldom seen or shot. 
The specimen obtained during my former Expedition and recorded under the name 
of Scops bakkamoena lempijt Horsr. (Kungl. Svenska Vetenskapsakademiens Handlingar, 
B:d 50, No. 8, p. 61) most probably belongs to the northern race and ought to be called
