Genus— WHIT LOCK A. 
Whitlocka Mathews, Austral Avian Record, 
VoL I., pt. 5, p. 115, Dec. 24tli, 1912. 
Type (by original designation) .. .. Climacteris melanura Gould. 
I diagnosed this genus : “ Differs from Climacteris in its shorter, stouter 
bill and stronger feet and comparatively much longer first primary ; from 
Neoclima in its broader, heavier bill and longer first primary, though shorter 
wing.” 
This little Northern group is well distinguished by its dark coloration 
and delicate build, while in addition to the items above quoted the wing 
formula also differs. 
T his group seems to have a peculiar smell, which is not recorded in 
connection with other Climacterine birds, yet is most noticeable in the two 
species of this genus. 
Note. _In Part II., p. 103, the third line from the bottom, "eyebrow distinct, smaller, C. minor,” should 
be on a line by itself, and be a line higher.
