86 NILS GYLDENSTOLPE, ZOOLOGICAL RESULTS OF THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 
Of this species which is rather common in the Southern Malay Peninsula, only a 
single specimen was obtained in a thick evergreen forest near a small creek called Hat 
Sanuk quite close to the Tenasserim boundary on about Lat. N. 11° 50’. 
At this same place I observed a few more specimens, which were very difficult to 
detect among the dense foliage as they kept rather high up in the gigantic trees. 
In any other part of Siam the Green Broadbill was never met with. 
Outside Siam and the Malay Peninsula it inhabits Southern Tenasserim, Sumatra 
and Borneo.

od juv. Meh Nja Min 77/7 1914. L—135 mm.; W= 78 mm.; T = 33 mm.; C = 10 mm. — Irides: 
blackish grey. Bill: horny brown with yellow edges. Legs: greenish yellow. 
The Long-tailed Broadbill is sparsely distributed over the damp evergreen hill- 
forests of Northern Siam. During my journey I only obtained a young male which was 
caught by one of my coolies on the road between Muang Fang and Chieng Hai. 
It has quite a different plumage from that of the adult bird and as I can find no 
description of such a young bird, I herewith give a short description of it. 
Forehead, occiput, nape and whole upper plumage green; ear-coverts green but 
darker than the crown; a few feathers on the lores, a large spot over the ear-coverts, 
feathers below the eye and at, the angle of the bill bright yellow; wing-coverts, tertiaries 
and secondaries green (the latter of a brighter colour) primary coverts black edged with 
greenish blue on the outer webs; primaries blackish edged with greenish blue on the 
outer web; a large patch of glistening cobalt blue on the outer webs of the inner primaries; 
chin and throat yellowish green; breast, abdomen and under tail-coverts pale green; 
tail-feathers bluish green above, blackish beneath. 
162. Eurylemus javanicus. Horsr. — Horsfield’s Broadbill. 
Eurylemus javanicus: Gyldenstolpe II; Gyldenstolpe III p. 229; Robinson I p. 96. 
@ Koon Tan *4/5 1914. L= 210 mm.; W= 106 mm.; T=71 mm.; B = 36 mm.; Tarsus = 21 mm. 
— Koon Tan */5 1914. L= 205 mm; W= 105 mm.; T= 68 mm.; B = 36 mm.; Tarsus = 21 mm. — 
Jrides: black. Bill: as in the Fauna of British India. Legs: brown. 
Seems to be fairly rare in Siam and only two specimens were shot out of a small 
party by my Siamese collector. 
The tail-coverts in my specimens are not bright yellow as recorded in the literature 
but pale yellow with a rosy tinge, and the spots at the bases of the primaries are pure 
white instead of yellow. The tail-feathers, except the central ones, have a subterminal 
whitish spot. 
Horsfield’s Broadbill has also been obtained by Mr. EIsENHOFER’s collector at Koon 
Tan and Pa Hing, both places in Northern Siam, and by Rosinson in the Bandon 
Province of North Eastern Malay Peninsula and these are the only records I know about 
from Siam.
