Black-vented Ground-Bird, have been displaced in favour of more suit¬ 
able names; and some long formal names such as Great Brown King¬ 
fisher, White-shouldered (Caterpillar-eater* and Bose-breasted Cocka¬ 
too, have been replaced by Laughing Kookaburra, White-winged Triller, 
and Gal ah respectively. 
A few long names such as White-throated Grass-Wren and Black¬ 
faced Cuckoo-Shrike have so far defied efforts for improvement. 
Appropriate, descriptive, children’s, and poets’ names are still required 
for many Australian, birds. 
After considerable discussion, a compromise was effected with Mr. 
Gregory M. Mathews, who offered to accept large genera if the 
numerous generic names as used in his later lists were included as 
subgenera. This offer was accepted. The subgeneric names have been 
inserted in the form prescribed by the International Buies, the sub- 
generic name being included in parentheses between the generic and 
specific names, e.g., Malurus (Leggeornis ) lamberti. 
In the case of Creadion, the Committee considered that the type 
species was fixed as the Aew Zealand Saddleback by Vigors and Ilors- 
field in 1827. Mr. Mathews considered it was fixed by Lesson in 1830 
as the Yellow Wattle-bird. 
In every instance but; two the oldest valid name lias been used. 
One name^ not so used is that of the migratory Snipe, GaUinago. In 
opinion 67, the International Commission accepted, with 200 other 
names, GaUinago of Koch, 1815, as finally fixed. The discovery of a 
prior name — Capella of Frenzel, 1801 — caused some ornithologists to 
ignore the authority of the International Commission. Australia is 
keen to support the League of Nations, and Australian ornithologists are 
keen to support the International Commission, the League of Nations 
in matters zoological. They have retained GaUinago. 
The second case is the specific name for the widely ranging Slender 
Thornhill. 
In 1905 Mr. Zeitz, Curator of the Adelaide Museum, named a bird 
from Leigh’s Creek Acanihiza tenuirosiris. This name having been 
used by Lafresnayc in 1841 was not available or valid. Mathews in 
1911 published a substitute name (Bulletin B.O.C., Yol. 27, p. 97 
1911) A. morgam. Above this on the same page lie named a “new” 
species from Lake Way, Western Australia, "as A. iredalei . The 
“new” species proved to be identical with the other. Here, though 
A. iredalei is apparently a prior name on the page, yet A. morgani 
published simultaneously really appertains to a topotype, and refers 
to an earlier name. A. morgani has been accepted, thus retaining for 
the species the original type locality. 
A possible third case occurs in connexion with the specific name 
for the Kookaburra. The date of publication of Alcedo gigas of 
Boddaert is fixed as 1783. The publication of A. novQe-guincae of 
Hermann is fixed as “preferably September, 1783.” The evidence 
is, at least, indefinite. 
The Committee lias followed the International Commission and the 
Code in the matter of “ on e-letter is in.” An offer from Mr. Mathews 
to compromise by considering names differing only in gender endings
