bottom near the front of the membrane ; tarsi and toes long, the first more 

 than half the tail, which is very short, giving, together with the rounded 

 wing, the bird a very ball-like appearance, much reminding of Troglodytes ; 

 rictal bristles short ; plumage mottled above and below, the feathers of the 

 back with white or pale fulvous shaft-streaks ; rump-plumes unstriped, very 

 long and fluffy ; superciliary streak and triangular spots on the tips of the 

 wing-coverts and inner secondaries white or pale fulvous." (Buttikof er) . 



Both Mr. Ogilvie-Grant and Dr. Hartert agree in uniting Turdinulus 

 and Corythocichla in the same genus ; they have the same characteristics, 

 except in the former the tail is extremely short, the exposed portion of the 

 tail extending barely half an inch beyond the tail coverts, while in the 

 latter they extend about an inch. 



Their wings are short and rounded, fitting close to the body, the first 

 four primaries graduated ; tail much shorter than the wing ; upper plumage 

 squamated ; bill straight ; rictal bristles weak ; no hairs overhanging the 

 nostrils ; nostrils slits, with no actual overhanging membrane.
