The Red-headed Trogon was generally distributed över the well-wooded parts of 

 Northern Siarn, though nowhere very common. 



The colour of the irides seems to be variable. One fine male from Northwestern 

 Siarn has the iris bright red while other males in my collection have it påle brown or 

 inclining to reddish brown. The females, however, have the irides constantly brown.

Irides: brownish black. Bill: bluisb black. Legs: bluish green. 



The Yellow-breasted Trogon is generally distributed över the whole of Northern 

 Siarn, where it seems to be less addicted to the evergreen forests than Pyrotrogon erythro- 

 cephalus Gould. 



It is quite a tame and fearless bird. When disturbed it retires to a tree close by 

 the place from where it was flushed away and then it always turns the back with its 

 plain colouring against the distnrber, never showing the brilliant colonrs of the breast and 

 miderparts of the body. It has a smacking note which is fairly loud and may be heard 

 some distance.
