gO TOURNAL OF SCIENCE. 
3. ‘* Notes on the Geology of the Southern Portion of the 
Clarence River basin,” by Professor Stephens. This was an ac- 
count of the Sugar lands of the Clarence, explaining the mode of 
their formation, and their relation to the coal measures which un- 
derlie them uncomformably. The period of deposition ot these 
latter rocks was also considered, and their immediate superposition 
upon the vertical Siluro-Devonian Slates and Quartzites described. 
The existence of a great N. and 8. fault at the present outcrop of 
these rocks was demonstrated, and the probable existence of others 
near the present coast line, supported by various considerations. 
Mr. Macleay read a communication from Baron von Miller, 
on the Orthography ot Linné’s name. 
Mr. Macleay also read the following note: —The October num-. 
ber of the Annals and Magazine of Natural History, contains an 
article on a case of commensalism of a Cavanx and a Crambessa, 
written by M. Godefroy Lunel, and translated by W.S. Dallas, 
F.L.S. In this paper M. Lunel speaks of the commensalism of 
Fishes and Medusz as something doubtful and unknown, but the 
following 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 Commissiouers. Alluding to the Yellow- 
tail ‘‘ Tvachurus tvachuvus’’ it says:—‘* The very young fry havea 
most extraordinary and ingenious way of providing for their safety 
and nutrition at the same time; they take up their quarters inside 
the umbrella of the large Medusez, where they are sate from their 
enemies, and are, without any exertion on their part, supplied 
with the minute organisms which constitute their food, by the con- 
stant current kept up by the action of the curtain-like cilia of the 
animal,”
