Fam. Bubonidae. 



240. Ketupa zeylonensis zeylonensis. Gm. The Brown Fish-Owl. 



Ket apa 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 träets near rivers and creeks at least in Northern 

 and Central Siarn. 



Only one specimen was shot — at Koon Tan — and a few more were observed at 

 tliis same place and in the neighbouring country. 



Outside Siamese Territory this species has been found in British Tndia, Ceylon, 

 Southern China, Hainan and Cochin China. In the Malay Peninsula it seems to be very 

 rare though some specimens ha ve been lately recorded from Träng. 



241. Huhua nipalensis. Hodgs. — The Forest Eagle-Owl. 



llnhiid nepalensis: Gairdner p. 150. 



$(?) Koon Tan 1914. W = 420 mm.; T — 238 mm.; C = 36 mm. 



A fine specimen of the Forest Eagle-Owl was caught in a trap at Koon Tan by one 

 of the Railway Engineers who kindly presented it to me. »One af ternoon », he told me, 

 »a 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 liigh altitude. 



Gairdner has recently recorded this species from the Batburi and Petchaburi 

 Districts of Southern Siarn. 



242. Otus bakkamoena lettia. Hodgs. — The Collared Scops Owl. 



J Pak Kob S2 / 3 1914. L = 195 mm.; W = 158 mm.; T = 88 mm.; C = 15 mm. — $ Cbum Poo 

 3 / 5 1914. L = 220 mm.; W = 167 mm.; T = 93 mm.; C = 17 mm. - - <$ juv. Koon Tan 3 % 1914. L = 

 160 mm.; W = 117 mm. — Irides: brown (black in young). Bill: born colour or yellowish green. Legs: 

 ligbt brown. 



In the most northern parts of Siarn the Collared Scops Owl was not uncommon, 

 thougli 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 lempiji Horsf. (Kungl. Svenska Vetenskapsakademiens Handlingar, 

 B:d 50, No. 8, p. 61) most probably belongs to the northern race and ought to becalled
