Pisciculture. 
THE CHRATODUS. 
In will be in the recollection of our readers that Mr. D. O’Connor, of Oxley—to 
whom we have been indebted, on different occasions, for interesting articles 
on Pisciculture—took from Queensland some live Ceratodi, which fish is only 
found in the Wide Bay waters—the Burnett and Mary Rivers. He was singu- 
larly fortunate in his experiment, as he landed the fish safely in London. 
Their arrival at once appealed to the London Zoological Society, which 
purchased two of them for £90; and Mr. O’Connor was offered £100 for the 
remaining two, if he would land them alive at the Jardin des Plantes in Paris, 
This the lucky pisciculturist will doubtless do. 
Avery remarkable coincidence happened in connection with the 
arrival in London of the Ceratodi. There is a fish which inhabits South 
American waters, much akin to the Ceratodus. Its scientific name is Lepido- 
siren, mention of which has been made in this Journal. A gentleman of zeal, 
equal to that of Mr. O’Connor, took home a living fish of this genus, and 
arrived in London simultaneously with the Queenslander and with a third 
traveller who came from Africa with stuffed specimens of new fish indigenous 
to Lake Tchad. So remarkable an incident was made the occasion of a special 
meeting of the Royal Society, at which meeting the three gentlemen were 
invited to address the members on the very important subject of these and 
other fishes of the three countries. 
Mr. O’Connor has determined that on his return he will bring living Gourami 
from Java, or perhaps from the Mauritius, to Queensland, whose climate and 
waters are eminently suited to the habits of the fish. A description of the 
Gourami, with illustrations, will be found in Vol. T., Part IV., p. 340, of this 
Journal. 
General Notes. 
QUARANTINE FOR PLANTS. 
Ariupina to the steps taken to prevent the intrusion of the San José Seale, 
our contemporary, Meehans’ Monthly, has the following wise remarks :—“But 
the truth is, the scale does not need looking after—not by law, for the scale 
will travel in spite of all law and its useless expenditures. Cultivators should 
be encouraged to look for and destroy the scale. It is as sensible to make 
laws that there should be quarantines against weeds as against insects. Like 
love, they laugh at ocksmiths,”’
