The Heart-spotted Woodpecker was rather rare at the localities visited by the Ex- 

 pedition and was only observed in Northern Siarn where it occnrred in thick, evergreen 

 jungles or in open deciduous forests. 



As regards the eolour the Siamese specimens agree perfectly well with the descrip- 

 tion in the literature but the males have only the forehead speckled with minute spöts 

 of yellowish bnff; the occiput, nape and crest-feathers being pure black with a faintgioss 

 of purple. 



In the females the lower parts are much darker than those of the males. These 

 parts are almost black in the females while in the males they are dark olivaceons. Only 

 the thighs, vent and under tail-coverts are black.

The Great Slaty Woodpecker is by no means a common birdin Siarn, thongh gener- 

 ally distributed över the Northern parts of the conntry. As it is very shy and on the 

 same time keeps to the highest trees it is not easy to obtain. It goes abont either in pairs 

 or in small parties and its shrill call is often heard. In the Malay Peninsnla, Sumatra, 

 Borneo and Java the smaller race occurs and this is the typical M . p. 'pulverulentus Temm.

This beautiful Woodpecker was rather rare in the ]>arts of Siarn visited by the Ex- 

 pedition and I only succeeded in obtaining two specimens which both were shot in decid- 

 uous forests. Like the Great Slaty Woodpecker (Mulleripieus pulverulentus harterti, 

 Hkssk.) this species is also very shy and difficult to obtain. It, however, never seems to 

 live very high np in the large trees and it was mostlv observed near the ground. It goes 

 about in small parties of about 4 to 6 birds.
