96 NILS GYLDENSTOLPE, ZOOLOGICAL RESULTS OF THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 
180. Hemicercus canente. Lxzss. — The Heart-spotted Woodpecker. 
Hemicercus canente: Oustalet 1899 p. 267; Gyldenstolpe I p. 50; Gyldenstolpe II; Gyldenstolpe TI p. 230. 
do Chum Poo 3/5 1914. L = 145 mm.; W = 95 mm.; T == 37 mm.; C = 22,5 mm. — @ Pak Koh 
54, 1914. L =.156 mm; W = 97; T= 39 mm.; C = 22,5 mm. — Irides: blackish brown. Bill: black. 
Legs: black. 
The Heart-spotted Woodpecker was rather rare at the localities visited by the Ex- 
pedition and was only observed in Northern Siam where it occurred in thick, evergreen 
jungles or in open deciduous forests. 
As regards the colour the Siamese specimens agree perfectly well with the descrip- 
tion in the literature but the males have only the forehead speckled with minute spots 
of yellowish buff; the occiput, nape and crest-feathers being pure black with a faint gloss 
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 olivaceous. Only 
the thighs, vent and under tail-coverts are black. 
181. Miulleripicus pulverulentus harterti. Hrsse. — The Great Slaty Woodpecker. 
Miilleripicus pulverulentus harterti: Gyldenstolpe I p. 50; Gyldenstolpe II; Gyldenstolpe IIT p. 230. 
Alophonerpes pulverulentus: Robinson & Kloss p. 47; Robinson I p. 95. 
d. Doi Par Sakeng */; 1914. L = 476 mm.; W = 242 mm.; T = 186.mm.; C = 65 mm. — ¢ Koon 
Tan *'/, 1914. L—= 485 mm.; W = 235 mm.; T = 191 mm.; C == 64 mm. — Irides: brown. Bill: horn 
colour with the base plumbeous grey. Legs: plumbeous or dark greenish olive. 
The Great Slaty Woodpecker is by no means a common bird in Siam, though gener- 
ally distributed over the Northern parts of the country. As it is very shy and on the 
same time keeps to the highest trees it is not easy to obtain. It goes about either in pairs 
or in small parties and its shrill call is often heard. In the Malay Peninsula, Sumatra, 
Borneo and Java the smaller race occurs and this is the typical M. p. pulverulentus TEM. 
182. Thriponax javensis feddeni. Branr. — The Burmese Great Black Woodpecker. 
Thriponax javensis feddeni: Gyldenstolpe II; Gyldenstolpe HII p. 230. 
Thriponax javensis: Gyldenstolpe I p. 50; Miller p. 424; Robinson & Kloss p. 47. 
3d Hue San */s 1912. W = 212 mm; T= 157 mm; C = 49 mm. — @ Koon Tan 19/, 1914. 
L = 395 mm.; W = 215 mm.; T = 159 mm.; C = 47 mm. — Irides: yellowish white. Bill: black. Legs: 
greyish blue. 
This beautiful Woodpecker was rather rare in the parts of Siam 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 (Miilleripicus pulverulentus harterti, 
HeEssg.) this species is also very shy and difficult to obtain. It, however, never seems to 
live very high up in the large trees and it was mostly observed near the ground. It goes 
about in small parties of about 4 to 6 birds.
