(A.) Beginning of the dorsal consiclerahly before the anus. 
(a.) At about two inches, in a specimen of twenty inches 
long — Dief'enbachii. 
(b.) At one inch, on a specimen of seventeen inches long — 
AucMandi. 
Beginning of the dorsal rather before the anus — Australis. 
In the latter the pectorals are very small, and are much 
larger in AucMandi. I must add that Dr. Gunther considers 
Dieffenbachii as the same as the European Latirostris ; but it is 
evident that either this zoologist is mistaken, or that this 
eel has been imported to New Zealand, as several other Euro- 
pean fishes have been to Australia. 
Eels seem to extend over all the antarctic regions, and in my 
notice of the fishes of the Cape of Good Hope I mentioned a 
sort found in that part of South Africa.

THE EEIi. 
This is the common eel of the Yarra, and of several other 
streams of Victoria and Tasmania ; but it appears doubtful 
whether it extends to New Zealand. Dr. Eichardson has already 
pointed out some slight differences between the specimens from 
each locality. 
This eel, though covered with minute scales, arranged in a 
lattice work way, is very smooth and slippery. The pectorals 
are not longer than the cleft of the mouth. 
Its colours are very changeable; generally it is of a dark 
green, with the lower parts lighter and grey ; sometimes it 
shows faint transverse spiots or bands of a more obscure 
tinge. The dorsal and anal are often in a great part yellow. 
It attains large dimensions.
