figs. 4-7), further dwelt on the taxonomic importance of the 
equally remarkable characters of the syringeal muscles exhibited 
alike by this form and J/enura, which he accordingly placed 
together in a division of the Acromyodian Passeres, differing from 
all the rest and since recognized by Mr. Sclater (Ibis, 1880, p. 345) 
as a Suborder PSEUDOSCINES—the SUBOSCINES of the present 
work. <A detailed anatomical description of Atrichornis has, how- 
ever, yet to be given, and a comparison of many other Australian 
types is needed?! before it can be certainly said to have no nearer 
ally than Jenura. Both the known species of Scrub-bird are 
about the size of a small Thrush—JA. clamosa being the larger of 
the two. This species is brown above, each feather barred with 
a darker shade; the throat and belly are reddish white, and there 
is a large black patch on the breast; while the flanks are brown 
and the lower tail-coverts rufous. 4. rufescens has the white and 
black of the fore-parts replaced by brown, barred much as is the 
upper plumage. Both species are said to inhabit the thickest 
“scrub” or brushwood forest; but little has been ascertained as 
to their mode of life except that the males are noisy, imitative of 
the notes of other birds and given to violent gesticulations. The 
nest and eggs seem never to have been found, nor indeed any 
example of the female of either species to have been procured, 
whence that sex may be inferred to escape observation by its 
inconspicuous appearance and retiring habits. 
SEA- used as a prefix in more birds’ names than can here be 
mentioned, and often without much precision. ‘Thus in one part 
of the country SEA-CROW may be the Cuoucu, in another the 
CoRMORANT, and very generally (especially inland) a GULL, while 
in America it may mean either a CooT or a SKIMMER according to 
locality. SEA-DOTTEREL and SEA-LARK are names of the 
Ringed Prover, SEA-MALL, -MEL (ef. ScamEL) or -MEW have 
been used indifferently for GULLS: SEA-PARROT is the PUFFIN, 
SEA-PHEASANT the Prntait, SEA-PIE the OyYSTER-CATCHER, 
SEA-SWALLOW a Tern, and so on.

SECRETARY-BIRD, a very singular African form, first accur- 
ately made known, from an example living in the menagerie of 
the Prince of Orange, in 1769 by Vosmaer,? in a treatise published 
fig. 1, p. 29); but a fuller description is needed, and the figure in Garrod’s 
paper, presently noticed in the text, is bad. 
1 Forbes shewed (Proc. Zool. Soc. 1882, p. 544) that OnrHoNnyx (p. 657) did 
not belong to the group as at one time had been suspected.
