e2 GYLDBNSTOLPE. BIRDS COLLECTED BY THE SWEDISH ZOOLOGICAL EXPEDITION TO SIAM. 



from Siarn, but I can not find that the specimens in my collection are darker than 

 other specimens. They also show greater dimensions on the wings than in the 

 specimens measured by Parrot as will be seen below. I therefore beheve that the 

 Rollers found in Siam belong to the typical Coracias ajjinis Mc Clell. and that 

 tliere is no right in giving the Siamese form a new subspecific name.

The specimen shot on the 22nd of March has the plumage much worn and the 

 measures are then quite uncertain. 



For eomparison I novv give some measures of Coracias ajjinis theresim according 

 to Parrot.

102. Eurystomus orientalis L. — The Broad-billed Roller was only observed 

 once in a glade in the great primeval forests south-east from Nong Koh, a small 

 village in the Chantabon province. Here I noticed 2 specimens — probably a pair 

 — on the 24th of April and I succeeded in getting the female, though it was very 

 shy and wary. The birds seemed to like high trees best and always rested at the 

 top looking for passing insects, wliich they took on the wing. When I had shot 

 the female the other bird uttered a faint note and circled round for some time but 

 always out of range. Then it suddenly uttered a sharp, harsh sound and disappeared 

 into the wood. 



Length = 275 mm. Tail =103 mm. 



Wing =181 » Culmen = 26 ^ 



Fain. Meropida?. 



103. Merops orientalis birmanus Neum. — This species was the most com- 

 mon bird belonging to the family Blerojyidce on the localities visited by the Expedi- 

 tion, but it was never observed in or near the primeval evergreen forests.
