228 Messrs. E. L. and E. L. C. Layard on the 
ference in tint, even without a bird from the larger island 
to compare withit. The billis corneous, lower mandible the 
palest ; legs black; soles of feet dull yellow; iris pale yellow. 
Length 14. It preys upon Grylle and such like insects, 
Coleoptera, ants, &c., also on fruit. We found it equally 
among the cocoa-nut groves and the high forest-trees. The 
natives say its favourite food is the large locust (Locusta impe- 
rialis) that devours the leaf of the cocoa-nut tree. They call 
it “ Halou,” and say that it does not exist on Maré, where 
the locust abounds. On suggesting that it might be easily 
introduced, we were told that the inhabitants preferred the - 
insect, the female of which, a fly of six or seven inches 
length, and when in season full of eggs the shape, size, and 
colour of green oats, is much sought after as an article of 
food, and said, even by a white man, to be “ delicious,” re- 
sembling potted shrimps!! It probably never existed on 
Maré, as the natives of that island have no name for it. 
Canon Tristram alludes to a Graucalus from Mallicolo 
Island, New Hebrides, obtained by L. L., as differing in tint 
from G. cinereus, being greener. Lately, when looking over 
our collections, we placed a specimen from “ Espirito Santo” 
alongside the latter, and were struck by the lighter and bluer 
tint prevailing over it. We suspect these are all local races, 
gradually changing into what will hereafter be good species.

Peculiar to Lifu, to the total displacement of P. moriariensis 
and P. assimilis, Verr. & DesM. These two, and also our two 
New-Caledonian Hopsaltrie (E.caledonica and E. flavigastra), 
are conspicuous by their absence! This fine species, far 
exceeding in size those of the main island, is found only in 
the forest, keeping chiefly to the undergrowth, which it tra- 
verses in search of its favourite food, snails of the genus 
Helicina, which were never absent from the stomachs of those 
killed by us. The female is far scarcer than the male, or,
