3/3 1914. L = 288 mm.; W = 193 mm.; T = 106 mm; C = 21 mm. — Irides: brown. Bill: brick red 
with the tip of the upper mandible black. Legs: pale coral. 
This subspecies which has been separated from the typical H. o. orientalis Linn. 
on account of its having the apical half of the outer webs of the rectrices blue, except at 
the utmost tip, was rather rare in the parts of Siam traversed by my Expedition. It 
occurs in the same localities as H. o. orientalis with which it probably interbreeds. As 
shown by STRESEMANN in his recent paper »Die Formen von Hurystomus orientalis L.» 
the specimens from the Malay Peninsula and Tenasserim are practically intermediate 
between typical # o. orientalis and E. o. calonyx. 
This is also confirmed by the specimens in my Siamese collection which therefore 
ought to be better named: 
Eurystomus orientalis orientalis 2 calonyx. 
Fam. Psittacide. 
234. Paleornis eupataria magnirostris. Ba.u. 
Paleornis indoburmanicus: Gyldenstolpe UI p. 233; Gyldenstolpe I p. 60. 
& Koon Tan 4/5 1914. L = 455 mm.; W = 190 mm.; T = 290 mm.; C = 36 mm.; Depth of upper 
mandible at cere = 21 mm. — Irides: yellow. Bill: red. Legs: yellowish brown. 
This beautiful Paroquet was rather rare and apparently very locally distributed 
over the northern parts of the country. It never occurred in large flocks like the other 
members of the family and when observed it was either single or in small parties of 5 to 
6 birds. 
The only specimen I got, clearly belongs to the race which was originally described 
from the Andaman Islands. In colour it resembles P. e. ewpataria Linn. from Ceylon, 
but is at once distinguished by its much larger size. P. e. magnirostris which I only con- 
sider as a mere subspecies of P. eupataria is chiefly characterized by its very high and 
massive bill. It also has an indication to a blue collar above the rosy collar on the nape, 
which is of the same colour as the top of the head. The blackish brown mandibular stripes 
are also rather narrow. 
235. Paleornis cyanocephalus rosa. Bopp. — The Eastern Blossom-headed Paroquet. 
Palgornis rosa: Oustalet 1899 p. 224; Gyldenstolpe I p. 60; Gyldenstolpe II; Gyldenstolpe III p. 233; Gairdner 
p. 150. 
The Eastern Blossom-headed Paroquet was quite common at Pak Koh, but further 
north it was rather rare and only a few specimens were noticed. It keeps exclusively to 
the dry forests and was never met with in the evergreen jungles.
