Genus— ETHEL ORNIS. 
Ethelornis Mathews, Austral Av. Rec., 
Vol. I., pt. 5, p. 110, Dec. 24th, 1912. 
Type (by original designation) ... ... Gerygone magnirostris Gould. 
The large-billed Gerygone, for which I proposed the above name, was 
differentiated as “differing from Pseudogerygone in its much stouter, wider 
bill, while the first primary is proportionately much longer than in that genus.” 
This diagnosis covers most of the species classed by Sharpe under Pseudo- 
gerygone , though according to his characters they should have been placed in 
Gerygone. That genus, however, is well characterised by its coloration as 
well as its structural features, and so the above name can be used for the 
Australian modestly coloured forms. In the wing-formation there is a little 
variation and quite an appreciable amount in the bill. There is little colora- 
tion change save in cJiloronotus, regarding which Gould wrote: “In form and 
in most of its habits and economy it offers some difference from the typical 
members of the genus Gerygone ; and it would be no great stretch of propriety 
to assign to it a new generic appellation ; the more lengthened form of its 
legs, the more rigid structure of its primaries, and the less development 
of the bristles at the gape are among the points in which it differs from the 
Gerygone fusca of the brushes of New South Wales.” 
In this case, as in many others, Gould contradicted himself by giving 
the length of the tarsus as five-eighths as against three-quarters in the 
latter. As a matter of fact, I can see little difference in the measurements, 
but that those of the latter may be longer is probable.
