ON ABROLHOS ISLANDS. 261 
by your Secretary arrived too late for this, and was, through Mr. Cossmann’s 
-kind intervention, printed in the Compte Rendu de la Société Géologique de 
France for February 7, 1921. Reprints of this French edition were furnished 
by the Société Géologique. 
3. In the Naturalist for September 1, 1920, the chief recommendations were 
quoted and contributors asked to adhere to them. Several requests for further 
oa of the circular and for previous reports were received and complied 
with. 
4. The editor of the Yorkshire Geological Society consulted the Secretary 
of the Committee on the correct way of writing specific names. Since the 
particular instances occurred in a paper on paleobotany, the reply sent was 
kindly read and approved by Dr. A. B. Rendle. Many otherwise competent 
zoologists seem unaware that an author’s name should be enclosed in brackets, 
e.g. Dalmanites caudatus (Briinnich), only when the species has been transferred 
from the genus in which the author originally placed it, e.g. Tvilobus caudatus 
Brinnich. It would be equally correct to write Dalmanites caudatus Briinnich sp. 
5. There is also confusion in some minds as to the use of brackets in connec- 
tion with generic and subgeneric names. ‘The trilobite just mentioned was 
long placed in the genus Phacops; this fact may be indicated thus—Dalmanites 
[Phacops] caudatus. At first Dalmanites was regarded as a subgenus of Phacops, 
and this would have been indicated correctly by: Phacops (Dalmanites) 
caudatus. 
6. A similar question was raised, and the opinion of the Committee asked, 
by Mr. J. C. Moulton, who, as editor of the R. Asiatic Society’s Journal, 
Straits Branch, has adopted the following method of printing trinomials :— 
CHLOROPSIS VIRIDIS Horsfield viriditectus Hartert. Here the essential 
departures from ordinary usage are the difference of type for the subspecific 
component of the name, and the insertion of the name of the author of the 
species after the specific component. 
The Committee agrees that the alterations introduced by Mr. Moulton tend 
to increased clearness. If it be ever necessary to give the name of the author 
of the species, it is no less necessary when the form referred to is one of the 
subspecies into which the species has been divided, and Mr. Moulton’s method 
of introducing it seems unexceptionable. 
The Committee does not wish by this expression of opinion to encourage 
the insertion of authors’ names in general writing, except when they are needed 
to avoid ambiguity. Mr. Moulton’s devices are best suited for such systematic 
lists as those in which he has employed them. 
7. In postage of the above correspondence the Committee has spent the 
sum of 4s. 9d., leaving an unexpended balance of 15s. 3d. The postage account 
is likely to be heavier in the coming year. The Committee therefore applies for 
its reappointment, with a grant of 1/. to cover such possible expenditure. 
Abrolhos Islands.—Feport of Committee (Professor W. A. 
Herpman, Chairman; Professor W. J. Dakin, Secretary; 
Professors J. H. Asnwortn and F. O. Bower) appointed to 
conduct an investigation of the biology of the Abrolhos Islands 
and the north-west coast of Australia (north of Shark’s Bay to 
Broome), with particular reference to the marine fauna. 
The investigation of the Abcolhos Islands in the Indian Ocean (marine fauna 
and flora and formation of islands) was undertaken with the help of grants 
_ from the Percy Sladen Fund, the Government Grant Committee of the Royal 
Society, and the British Association. 
Two expeditions were arranged and extensive collections were made in 1913 
and 1915. The grants were exhausted with the exception of a small amount 
out of that made by the Government Grant Committee of the Royal Society. 
During the years 1915 to date the collections have been distributed to various 
specialists, some of whom have already reported upon the same. 
Professor Dakin has written a narrative of the expeditions and a report upon
