O. b. lettia Hopes. This subspecific race is much larger than typical lempiji from the 
Malay Peninsula and has the feathering on the tarsi running down on the outer toe, while 
the bases of the toes in O. b. lempiji always are quite unfeathered.

Five specimens of the Brown Hawk-Owl were collected at different localities in 
Northern Siam. , | 
Several subspecies have been described of this bird being mostly founded on very 
slight characters. Unfortunately there is no material for comparison in the collections of 
the Royal Natural History Museum in Stockholm and I am therefore unable to ascertain 
which race the Siamese specimens belong to. 
They possibly are to be referred to the race which has been named Ninox burma- 
nica by Hume. This race was founded on specimens from Pegu and Tenasserim. Another 
race the typical Ninox scutulata RAFFLES inhabits and breeds in Japan and Northern 
China. It has been found wintering in Sumatra, Java and the Philippines and might 
just as well be found in Northern Siam too during the cold season. 
According to HARTERT both these races are very similar both as to size and general 
colouration of the plumage, though the head in N. burmanica is perhaps a little more 
grey than that of the typical species. 
Compared with specimens from Japan (Ninox scutulata scutulata Ra¥ru.) and with 
birds from the Malay Peninsula (Ninox scutulata malaccensis Eyton.) my Siamese spe- 
cimens seems to be intermediate as regards size and colour of the plumage. The Malayan 
race is, however, clearly distinguished by its much smaller size with wings measuring 
191—195 mm. (HARTERT.)

The Collared Pigmy Owlet was rather rare in the parts of the country visited by 
the Expedition. Only two specimens were observed in evergreen jungles, and the 
birds made their appearance just at dusk. They were not shy and only moved a short 
distance when disturbed.
