kinds as before.” ‘On the fishes of Bengal, Assam, and other 
provinces subject to the inundations of the larger rivers, we can 
exercise no control, nor is it desirable that we should, even were 
it in our power, the supply of fish being plentiful and constant 
enough ; but in the higher parts of the plains, near the foot of 
the mountains, where the larger Cirrhins and Barbels retire du- 
ring the dry season for the purpose of spawning, fisheries might 
be carried on with advantage to a considerable extent.” p. 461. 
As some species of the Indian fishes are found only in clear 
and rapid streams, they would not probably thrive well, if at all, 
in tanks where the water would be still. Should it be consid- 
ered desirable to propagate to any extent such species, our author 
suggests, that “the most suitable vivarium for such species might 
be formed by stopping upa clear mountain stream to a certain 
depth, and filling the irregularities of the bottom with sand, gravel 
and stones; there should be a current in the water, and to prevent 
the escape of the fish, a grating should be fixed below; at the 
opposite end a stronger grating, if necessary, to prevent the intro- 
duction of rubbish during floods, as well as, the escape of the 
fish, should the fall not be sufficient for the latter purpose.” _p. 
347, Occasional remarks are found. relating to the altitude at 
which fishes are known to live in India. Speaking of the Orei- 
nus guttatus, Dr. M’Clelland observes, it is found “in rivers in 
different parts of Boutan, between the elevation of two and five | 
thousand feet. It may occur higher, but Mr. Griffith remarks, 
that in valleys above five thousand feet, though fine, clear streams 
are common, yet fishes of any kind do not occur in them, and 
the natives assured the mission to which he was attached, that 
no fish existed at such elevations.” p. 345. The Gonorhynchus 
petrophilus “inhabits streams in Kemaon at an elevation of six 
thousand feet above the sea, and has been observed by Lieut. 
Hutton at similar elevations in the mountains north of Simla, as 
well as by Dr. Campbell in Nipal.” _p. 371. 
And again, “whether any other kind of fishes may yet be 
found in still higher altitudes. than those at which the Gono- 
thynchs and Mountain Barbels disappear, is a problem in the dis- 
tribution of this class of animals, that travellers in the Himalaya 
and other lofty regions must decide._In the limpid streams which 
Mr. Griffith passed. with Capt. Pemberton, at elevations of from 
six to eight thousand feet in.Boutan, no inhabitants were found ;
