It is interesting' to find that the earliest use of the name 
Emu in English occurs in ‘ Pnrchas his pilgrimes,’ where 
the bird is stated to occur on Banda Island in the Molucca 
group. The bird referred to was probably a Cassowary, which 
had been brought to Banda from Ceram. Skeat and the 
New English Dictionary state that Eme or Ema (whence 
Emu) is a Portuguese word for an Ostrich or Crane, 
but Mr. McClymont believes that the derivation is from 
a neama/ ; an Arabic name for the Cassowary, distorted by 
the Portuguese into “ uma ema ” and thence into Emu. 
The volume is illustrated by three well-produced plates 
in black and white, and is a beautiful example of book¬ 
making. 
Mathews on Australian Birds. 
[The Birds of Australia. By Gregory M. Mathews. Yol. viii. 
pts. 3 & 4, pp. 145-24, pis. 382-394. London (Witherby), Aug. & Oct. 
1920. 4to.] 
In these two parts Air. Mathews continues his account 
of the Muscicapidse with the genera Ethelornis , Pseudo- 
gerygone , Iredaleornis, Poecilodryas 3 Tregellasia , Kempiella , 
Pachycephala , and Lewinornis. 
This family has always been a source of trouble, as it has 
sometimes been included in the Turdidse, while certain 
genera have been referred to the Laniida^, as for instance 
Pachycephala. 
Ethelornis was formed by Air. Mathews to contain most 
of Sharpe’s species of Pseudogerygone ; they are compara¬ 
tively large-billed, and all the nine members are of modest 
coloration. They are largely found in mangrove-swamps, 
but the habits of the various forms, both in this genus and 
its nearest neighbours, are but little known, except in the 
aggregate. Two subspecies are recognised. 
E. cairnsensis is now raised to specific rank; it is brunnei- 
pectus of Sharpe, from Australia, but not New Guinea. 
Here again there are two subspecies, one ( robini ) being new. 
E. tenebrosas has three subspecies, of which one ( whitlocki) 
was formerly referred in error by Air. Mathews to
