will dismiss the odour of the acid, and are then placed in 
strong spirit. If anything should interfere with the process 
of mounting the specimens may be left in the spirit till it is 
convenient to continue the work. From the spirit they must 
be placed in an oil which is miscible with vhe substance in 
which the specimen is to be embedded. As the substance is . 
usually Canada balsam, clove or cedar oils are very service- 
able, the former being the most used on account of its cheap- 
ness. After the oil, the specimen should be placed in tur- 
pentine for about five minutes previous to embedding. The 
slides should be labelled with as many particulars as possible, 
the name and locality of the host being the most important.

A Noxious WEED New to New Sovurn WatLEs.— 
Martynia fragrans, Lindl., a Mexican plant has recently 
established itself in parts of the Narromine district, N.S.W. 
Two long incurved hooked beaks terminate the fruit and as 
these cling to any woolly or hairy substance, pasture animals 
unconsciously carry them long distances and distribute the 
seeds far and wide. Stockowners regard this plant as a for- 
midable new weed pest. M. proboscidea, Glox., was reported 
from the Young district, N.S.W., a couple of years ago.

New Recorps.—At the June meeting of the Linnean 
Society of New South Wales, Mr. D. G. Stead recorded, as 
an addition to the fish-fauna of New South Wales, a species 
of Serranid. Perch, Diagramma crassispinum. Ruppell (=D. 
affine, Gunther), a fine example of which, measuring 674mm.., 
and weighing 16}Ibs., had been received by the Department 
of Fisheries, early in May, from Port Macquarie. He also 
placed on record the second known occurrence of the Pristi- 
pomatid fish, Therapon jarbua (Forskal); a specimen measur- 
ing 143.5 mm., having been received from the same locality. 
At the same meeting Mr. A. R. McCulloch exhibited, by 
permission of the Curator of the Australian Museum, a small 
sunfish, Ranzania makua, Jenkins, which had been forwarded 
to Sydney by the Curator of the West Australian Museum. 
This species has hitherto been recorded from Honolulu and
