IANTHOCINCLA. 155 



Colours of soft parts. Iris red, lake-red or crimson ; legs and 

 feet very dark brown to almost black, claws horny-brown ; bill 

 black. 



Measurements. Length about 300 to 310 mm. ; wing 132 to 

 135 min. ; tail about 135 mm. ; tarsus about 45 to 47 mm. ; culmen 

 about 27 mm.

Habits. Davison says that it is a noisy but shy bird, avoiding 

 observation. " Not by any means uncommon, occurring in small 

 flocks of twenty or more, and keeping entirely, so far as I have 

 observed, to the forest, especially to the rawines where this is 

 densest." 



Genus IANTHOCINCLA Gould, 1835. 



Gates applied the generic term lanthocincla to those Laughing- 

 Thrushes which have no bristles at the base of the forehead, but 

 in which the nostrils are overhung by a few long hairs. The 

 genus differs in no other respect from Garrulax, and the division 

 is perhaps hardly necessary, but it is convenient for students arid 

 may therefore be retained. All the species are remarkable for 

 having the secondaries tipped with white and the bill is rather 

 narrow.
