ice, yet, on the water being thawed, the
fish became as lively as usual. Dr. RICHARDSON in the third vol of his
_Fauna Borealis Americana_, says the grey sucking carp, found in the fur
countries of North America, may be frozen and thawed again without being
killed in the process.]

_Hot-water Fishes_.--Another incident is striking in connection with the
fresh-water fishes of Ceylon. I have described elsewhere the hot springs
of Kannea[1], in the vicinity of Trincomalie, the water in which flows
at a temperature varying at different seasons from 85 deg. to 115 deg.. In the
stream formed by these wells M. Reynaud found and forwarded to Cuvier
two fishes which he took from the water at a time when his thermometer
indicated a temperature of 37 deg. Reaumur, equal to 115 deg. of Fahrenheit. The
one was an Apogon, the other an Ambassis, and to each, from the heat of
its habitat, he assigned the specific name of "thermalis."[2]

[Footnote 2: CUV. and VAL., vol. iii. p. 363. In addition to the two
fishes above named, a loche _Cobitis thermalis_, and a carp, _Nuria
thermoicos_, were found in the hot-springs of Kannea, at a heat 40 deg.
Cent., 114 deg. Fahr., and a roach, _Leuciscus thermalis_, when the
thermometer indicated 50 deg. Cent, 122 deg. Fahr.--_Ib_. xviii. p. 59, xvi. p.
182, xvii. p. 94. Fish have been taken from a hot spring at Pooree when
the thermometer stood at 112 deg. Fahr., and as they belonged to a
carnivorous genus, they must have found prey living in the same high
temperature.--_Journ. Asiatic Soc. of Beng._ vol. vi. p. 465. Fishes
have been observed in a hot spring at Manila which raises the
thermometer to 187 deg., and in another in Barbary, the usual temperature of
which is 172 deg.; and Humboldt and Bonpland, when travelling in South
America, saw fishes thrown up alive from a volcano, in water that raised
the temperature to 210 deg., being two degrees below the boiling point.

Fishes_, vol. i. In. p. xvi.]

_List of Ceylon Fishes._

In the following list, the Acanthopterygian fishes of Ceylon has been
prepared for me by Dr. GUeNTHER, and will be found the most complete
which has appeared of this order. I am also indebted to him for the
correction of the list of Malacopterygians, which I hope ere long to
render stil
