Genus— M ICROPODARGUS. 
Micropod ARGUS Mathews, Austral Avian Record, Vol. II., 
p. 57, 1913 .. .. .. .. .. .. Type M. ocellatus. 
Smaller Podargine birds, with comparatively stronger bills and longer tails, 
with the middle tail-feathers not attenuately pointed. 
In the Austral Avian Record^ Vol. II., p. 57, 1913, I gave as differential 
features : “ Differs from Podargus in its much smaller size throughout and 
in a comparatively stronger bill.” 
The bill is not so depressed as in Podargus^ and the nostrils are smaller ; 
the frontal bristles jutting forward and upward being more lengthened than 
those of the former genus. 
In the wing the fourth, fifth and sixth primaries are subequal, the sixth 
sometimes the longest : the third generally less than the seventh. 
The tail is longer than the wing, as a general rule, and though the two 
middle tail-feathers are pointed there is no attenuation, and the others show 
scarcely any points, though they cannot be called rounded at the tips. 
The feet are very much smaller than in the preceding genus. As hereafter 
shown, the inter-relationships of the species are quite obscure, and osteological 
investigation is strongly indicated. 
The sexes appear to be noticeably different in coloration, the female 
bemg completely rusty, while the male has the ground-colour of the under-parts 
whitish.
