vicinity of Trincomalie, the water in which flows at a 
temperature varying at different seasons from 85° to 
115°. In the stream formed by these wells M. Eeynaud 
found and forwarded to Cuvier two fishes which he took 
from the water at a time when his thermometer indicated 
a temperature of 37° Reaumur, equal to 115° of Fahren- 
heit. The one was an Apogon, the other an Ambassis, 
and to each, from the heat of its habitat, he assigned the 
specific name of <e thermalis." 1 
List of Ceylon Fishes. 
In the following list, the Acanthopterygian fishes of 
Ceylon has been prepared for me by Dr. Gtunthee, 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 still more extended, as well as that of the 
Cartilaginous fishes.

In addition to the two fishes above 
named, a loche Cobitis thermalis, 
and a carp, Nuria thermoicos, were 
found in the hot-springs of Kan- 
nea, at a heat 40° Cent., 114° 
Fahr., and a roach, Leuciscus ther- 
malis, when the thermometer in- 
dicated 50° Cent., 122° 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° Fahr., 
and as they belonged to a carnivo- 
rous genus, they must have found 
prey living in the same high tem- 
perature. —Journ. Asiatic Soc. of 
Beng. vol. vi. p. 465. Fishes have 
been 'observed in a hot spring at 
Maniha. which raises the ther- 
mometer to 187°, and in another 
in Barbary, the usual temperature 
of which is 172° ; 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°, being two degrees below the 
boiling point. Patterson's Zoo- 
logy, Pt. ii. p. 211; Yaebell's
