INDIAN FRESH-WATER FISHES. 
ferent from what they are now in far distant ages, 
while the present species of Labeo must apparently 
have sprung into existence since that time, as some 
species are now confined to India, and others to 
Egypt. 
There are several isolated waters in different parts 
of India, which it would be interesting to examine 
carefully and to note the species of fish to be found 
in them. 
The lake at Nynee Tal is a good example ; it is a 
large piece of water at a height of 6000 feet, having 
only one outlet, from which the surplus water escapes 
down a series of cascades, up which no fish could pos- 
sibly make its way. Some fishes have been imported 
into the lake, I believe, from below, but it would be 
very interesting to know what species inhabit it na- 
turally, and if they are the same as are to be found in 
the streams below. 
Again, in the Khasia hills, the southern face of the 
plateau, overlooking the Sylhet district, breaks off 
very suddenly, and the streams are precipitated over 
the edge from a height of 3000 or 4000 feet, forming 
waterfalls of several hundred feet at a time. Unfor- 
tunately, in this case, the natives have a habit of 
poisoning the streams, so that there are very few fish 
of any kind to be found on the plateau. 
However, there is one little species very common at 
Cherrapoonjee, and curiously enough it seems to be 
very closely allied, if not identical with a species 
(Danio ncilgherriensis) that occurs in the streams on
