46 NILS GYLDENSTOLPE, ZOOLOGICAL RESULTS OF THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 
74. Phylloscopus tennellipes. Swiyu. — The Pale-legged Willow-Warbler. 
Phylloscopus tennellipes: Robinson III p. 755. 
o Den Chai 8/2 1912. L = 95 mm.; W = 55,5 mm.; T == 44 mm.; C = 8 mm; Tarsus = 16 mm. 
— Irides: black. Bill: horn colour. Legs: pale brownish yellow. 
When writing my former account of the Birds of Siam (Kungl. Svenska Veten- 
skapsakademiens Handlingar Band 50. N:o 8. 1912) I omitted to record a specimen of 
Phylloscopus tennellipes Swinu. which I shot near Den Chai in Northern Siam. 
Fam. Turdide. 
75. Geocichla citrina. Lara. — The Orange-headed Ground-Thrush. 
Geocichla citrina: Robinson & Kloss p. 63; Gairdner p. 149. 
& Koh Lak Paa "/12 1914. L = 190 mm.; W = 107 mm.; T = 65,5 mm.; C = 18 mm.; Tarsus = 
30 mm. — @ Koh Lak 1/2 1914. L = 185 mm.; W =.106 mm.; T = 68 mm.; C = 18 mm.; Tarsus = 
29 mm. —- Irides: brownish black (4) or brown (2); Legs: flesh colour. 
Not common in the parts of the country visited by the Expedition and only two 
specimens were obtained in the Siamese Malaya. The male was shot on the slopes of a 
mountain near the Tenasserim boundary and the female on a limestone mountain, densely 
covered with evergreen jungle and situated quite close to the sea-shore. 
As a rule this species keeps on the ground only moving up in a tree when being dis- 
turbed in some way. It is not very shy but still rather difficult to obtain on account of 
its retiring habits. The female is much paler-coloured than the male and has the upper 
back and scapulars suffused with olive-green. 
76. Geocichla innotata. Buyra. — The Malay Ground-Thrush. 
Geocichla innotata: Robinson & Kloss p. 63; Robinson III p. 752: 
& Koon Tan. W = 115 mm.; T= 72 mm.; C = 19 mm.; Tarsus = 28 mm. 
Rather astonishing is that a specimen of the Malay Ground Thrush was shot by 
Mr. E. E1s—ENHOFER’s native collector as far north as at Koon Tan, where the other allied 
form G. citrina Lary. more probably ought to have been found. But the Koon Tan 
specimen does not show any sign of the white tips to the median wing-coverts which is 
the main point of difference between these two related forms. The two specimens ob- 
tained in the Siamese Malaya have very marked white tips on the median wing-coverts 
and therefore clearly belong to G. citrina Latu., if this really is a distinct species and 
not only a seasonal variation. However, I have used both these names until more 
material from different seasons and localities have been carefully examined.
