to the roofs of which it attaches its pendent nest as shown in the 
Plate. 
222. Origma rubricata Yol. III. PI. 69. 
Genus Calamanthus. 
Generic characters. 
Bill shorter than the head, dilated at the base, compressed late- 
rally towards the tip ; culmen sharp and advancing upon the fore- 
head ; nostrils lateral, large, oval, and covered by an operculum ; 
rictus destitute of bristles ; wings short, round, the fourth quill the 
longest, the third, fifth, sixth and seventh equal; tail rather short 
and round ; tarsi moderately long, defended anteriorly with indi- 
stinct scales ; hind-toe rather long, with a long claw ; lateral toes 
uneven, the outer one the shortest. 
This group comprises two species, one inhabiting Yan Diemen’s 
Land, the other Southern and Western Australia ; they are terres- 
trial in their habits, but occasionally perch on the smaller branches 
of the trees. 
223. Calamanthus fuliginosus Yol. III. PI. 70. 
224. Calamanthus campestris, Gould .... Yol. III. PI. 71. 
Genus Chthonicola. 
Generic characters. 
Bill short, gradually descending from the base ; the upper man- 
dible slightly notched at the tip, compressed laterally ; tomia curving 
inwards ; wings concave ; the first primary very short, the third, 
fourth, fifth and sixth nearly equal and the longest ; tail slightly 
concave, and all the feathers of an equal length ; tarsi moderately 
long ; toes short, the hinder toe somewhat longer than the middle 
one ; front claws more curved than in the genus Anthus . 
The single species known of this genus combines in a remark- 
able manner the outward appearance, habits and manners of the 
Acanthizce and Anthi , but is, I believe, more nearly allied to the 
former than to the latter. 
225. Chthonicola minima Yol. III. PI. 72. 
Sylvia sagittata, Lath. ? 
Rather widely dispersed over the grassy flats of New South 
Wales ; constructs a domed nest in a depression of the ground like 
the true Sylvice. 
Subfamily MOTACILLIN7E. 
Genus Anthus. 
Whether this Old World form is represented in Australia by more 
than a single species, is a point I have not satisfactorily determined ; 
every part of its extra-tropical regions, including Yan Diemen’s 
Land, is inhabited by Pipits which differ somewhat in size in almost 
every colony ; still their difference is so slight that I have hitherto 
regarded them as mere varieties or local races.
