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 T. 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. 



199. Trichostoma canicapillum.
