Davison, however, also says that he found them most abundant in 
thin tree jungle as well as in thick forest. In Tennasserim, he met 
them generally in pairs, and occasionally in small parties, and he 
describes habits, voice, ete., all as being very much like that of the 
partridges of the genus Arboriecola. 
Harington found them only in dense forests at considerable eleva- 
tions, as did Nisbett and Whitehead, and they were always in the 
thickest of the evergreen cover and never in thin forest. 
Grenus—CALOPERDIX. Blyth, 1865. 
In addition to possessing no supraorbital ossicles, this genus is differ- 
entiated very definitely both from Arboricola and Tropicoperdix by 
the formation of its legs. The tarsus is considerably longer than the 
middle toe and claw together, and is armed with one or more spurs. 
The feet are short and the claws, though straight, are much shorter. 
The wing is rounded as in Arboricola, and the tail consists of only 
14 feathers. 
It ranges from Java, Borneo and Sumatra, through the Malay, 
Peninsula into Western Siam and Tennasserim. 
Very little is as yet known concerning its habits, ete., which will, 
however, probably be found to very closely approximate those of the 
genus Arboricola.
