ICHTHYOLOGY 
Mr. Bostock says that it is known under the name of 
Perth Herring, " quantities being smoked with Banksia or 
sawdust, and sold in the fruit stores ; it is so called because 
it is found mostly about Perth, ten or twelve miles from the 
sea." 
Richardson had thought that the Australian sort of 
Chatoessus he described, might be the Come of Russel (Fishes 
of Coromandel, pi. 196), but at the same time he points out 
several characters which did not agree with the Indian fish. 
Dr. Gunther places this amongst his doubtful sorts, and gives 
the Western Australian one the name of Erebi. 
In the Proceedings of this Society for last year, I considered 
the Victorian fish as being this Erebi, but having since re- 
ceived the above-mentioned specimens from Freemantle, I find 
that the sort from the rivers of Western Australia is different 
from the one of the Murray, and that, the name of Erebi 
belonging to the first, I propose calling the other Richardsoni. 
OPHICHTHYS. 
OPHICHTHYS SERPENS. 
Ophichthys Serpens, Lacep., vol. ii., p. 198. 
Leptorhynchus Capensis, Smith, South Africa ; Fishes, 
pi. 6. 
The colour is brown ; the fins seem lower, and the body 
proportionately longer than in the European specimens, but 
I have none of these to compare with the Australian ones. 
PHILLOPTERYX ELONGATUS. 
One specimen, which seems similar to those from Adelaide. 
HIPPOCAMPUS ELONGATUS. 
Dorsal fin with eighteen rays standing on three body rings ; 
body elongate ; the broadest ring of the body not being 
one-fifth wider than the first two ; tubercules moderately 
acute ; no tentacles ; snout as long as half the head ; a short 
thin ridge in front of the eyes ; supraorbital spine conical,
