27th December, 1883. — 1. (Botanical.) — 2. Descriptions of Austra- 
lian Microlepidoptera, No. 10, by E. Meyrick, B. A. This is a continua- 
tion of the Oecophoridae of Australia, and deals with the genera Philobota, 
Leistomorpha, Compsotropha, and Eriodyta. About 70 new species are de- 
scribed. 3. Mr. Macleay read the following note: — The October 
number of the Annals and Magazine of Natural History, contains an article 
on a case of commensalism of a Caranx and a Crambessa, written by M. Go- 
defroy Lunel, and translated by W. S. Dallas, F.L.S. In this Paper 
M. Lunel speaks of the commensalism of Fishes and Medusae as something 
doubtful and unknown, but the following extract from the report of the 
Royal Commission on the Fisheries of New South Wales, written nearly 
four years ago, will show that the fact was well known to the Commissioners. 
Alluding to the Yellow-tail » 7>achurus trachurus« it says: — »The very young 
fry have a most extraordinary and ingenious way of providing for their safety 
and nutrition at the same time; they take up their quarters inside the um- 
brella of the large Medusae, where they are safe from their enemies, and 
are, without any exertion on their part, supplied with the minute organisms 
which constitute their food, by the constant current kept up by the action 
of the curtain-like cifra of the animal.« — Mr. Macleay exhibited a spe- 
cimen of the very remarkable and rare Fish Stphonognathus argyrophanes of 
Richardson. Four specimens were received lately by the Australian Museum 
from South Australia. — Dr. Cox gave an interesting description, with a 
record of measurements, of two gigantic Land Tortoises from the Galapagos 
Islands, and now in Sydney. The larger of the two is in the possession of 
Mr. Alexander McDonald of Potts Point. It is a male, weighs 6421bs, and 
measures from the nose to the tail 6 feet 2 inches; the shell is 4 feet 71/9 
inches in length and 5 feet 101/, inches wide. The other is a female and is 
owned by Dr. Manning at Gladesville. It is 5 feet 101/, inches in length 
from the nose to the tail, and the length and width of the shell are respec- 
tively, 4 feet and 5 feet. These far exceed in size the large tortoise at Cey- 
lon, which was exhibited to H. R. H. the Prince of Wales when he visited 
that island. — The President exhibited a very large specimen of Echinus, 
obtained by Mr. H. S. Wilkinson, from Lord Howe Island. It is one of 
the two edible species found at the island. 
4. Gesuch. 
Auf meiner Reise von Süd-Brasilien nach England hatte ich Ge- 
legenheit, eine Anzahl jener Wasserwanzen (Hylobates) zu fangen, 
welche auf der Oberfläche des offenen Meeres umherlaufen. Zur Be- 
stimmung und näheren Untersuchung der mitgebrachten Species fehlt 
mir die betreffende Litteratur. Ich würde sehr dankbar sein, wenn 
mir Jemand die zur Bestimmung der Hylobates-Species nöthige Litte- 
ratur auf kurze Zeit leihweise überlassen wollte.
