brown, the lateral feathers tipped with white on the inner webs. Eyes dark brown.

March, 1905. 
Adult male. Similar to the adult female. 
Immature. “ Pale rufous-brown feathers with distinct white shaft- stripes, intermingled 
with the dark slaty-grey feathers of the upper-parts ; wings blackish-brown, the 
greater wing-coverts and secondaries conspicuously tipped with white ; sides of the

inside with fine rootlets and grass. . . . Dimensions, over all, 3| to 4 inches by 
2f inches in depth ; egg-cavity 2 inches across by lj inches deep.” (Campbell.) 
Eggs. “ Clutch, two usually . . . colour, olive or bronze-green, of a darker shade on or 
around the apex. Most resemble those of the Dusky or Hooded Robins. 21-22 
mm. by 15-16.” (id.) 
Breeding-season. October, (id.) 
When the French naturalists, Quoy and Gaimard, on hoard the Astrolabe , 
visited King George Sound, they collected many birds, most of which were 
at that time undescribed. To these they gave new names, and two were 
called Muscicajpa georgiana and M. gularis. A few years afterwards Gould 
redescribed these as Eopsaltria griseogularis and leucogaster. This is one of 
the rare instances where Gould did not admit priority, as he retained his own 
names, citing the earlier ones as synonyms, and, peculiarly enough, under the 
wrong species. 
Thus, under the species Eopsaltria leucogaster , he cited M. gularis, whereas 
it was the same as M. georgiana, and his notes read : “ The White-bellied Robin 
is a native of Western Australia, but it is only to be met with in the hilly 
portions of the country. Gilbert states that the first specimen he procured 
was killed on the Darling Range, near the gorge of the River Murray, at an 
elevation of about seven or eight hundred feet, and that he afterwards met with 
it on the southern extremity of the same range, between Vasse and Augusta, 
but that he never observed it on the lower grounds between the mountain 
range and the coast. Like the other species of the genus, it was constantly 
seen clinging to the bark of large upright trees, or straight and small stems, 
in search of its insect food. It is extremely quiet and secluded in its habits, 
is almost exclusively confined to the neighbourhood of small mountain streams, 
where scarcely any other sound is heard than the rippling and gurgling of the 
water over the rocks, and on the slightest approach it immediately secretes
