Chap. X ] LIST OF CEYLON FISHES.

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° Keaumur, 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 " thermalis." 1 



List of Ceylon Fishes. 



In the following list, the Acanthopterygian fishes of 

 Ceylon has been prepared for me by Dr. Gtunthek, 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. 

 xviiL 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 

 ManiLa 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; Yarrell's
