Corythocichla brevicaudata herberti, subsp. nov. 
Differs from both C. b. brevicaudata and C. b. venningi in 
having the lower parts smoky ochre-brown, the feathers 
obsoletely streaked darker, and the abdomen albescent 
instead of chestnut rufous. The upper parts are like those 
of C. b. venningi, darker and more grey than in C. d. brevi- 
caudatu, but it differs again from the former in being much 
smaller, with a wing of 60 mm. as against 66-71 mm. 
It is possible that this should be described as a species 
rather than a subspecies, and I expect it will be found 
breeding in the same area as C. b. venningi.
