DUTCH BORNEO-EXPEDITION. 243 
in the jungle of an abandoned plantation. — Iris reddish 
brown, bill black, lower mandible grayish horn-color, feet 
flesh-color. 
Hab. Malay Peninsula, Sumatra and Borneo. 
In my above-quoted revision of the genus Turdinus and 
allied genera, I have already called the attention upon the 
curious fact that the male (N° 1280) has the tarsi abnor- 
mally short (18 mm. instead of 25), although this abnormity 
cannot be ascribed to rhachitis or any other obvious dis- 
ease. This striking fact is plainly shown in the adjoined 
figures which my friend Dr. Finsch was kind enough to 
Foot of Trichostoma rostratum. 
draw for this purpose. The bird in question is in every 
other respect a true 7.j rostratum, though the shortness of 
the tarsi does not agree at all with the character of the 
genus, which latter is chiefly based upon the tarsus being 
half the length of the tail. 
N.B. On his last journey on the Upper Mahakkam (No- 
vember 1898 to March 1899), Dr. Nieuwenhuis obtained 
seven males and eight females, some of which were imma- 
ture or still in down, but even the latter had the tarsus 
of normal length, i. e. 24—27 mm. A young bird, partly 
in down, has the upper surface, wing and the still very 
short tail of the same color as the adult bird, but the 
downy lower surface is dirty gray with a rufous tinge, and 
the base of the feathers white.
