The flounder I have taken in Currituck Sound, which is fresh 
water now, but was salt twenty years ago. It wasin winter and 
not in the spawning season. A species of ray was found in the 
interior of Eastern Africa and the sawfish is said to exist in Lake 
Nicaragua and in Laguna de Bay, near Manila. The others I 
have taken in fresh water or experimented with in aquaria. I 
also hear that pike (#so0x) are taken in the brackish and even salt 
waters of Maryland, but diligent inquiry among fishermen on 
the south side of Long Island, where the little “mud pike” (Z. 
americanus or £. fasciatus) is found in great numbers, failed to 
learn of its going-into salt water, although found in the salt 
bays where fresh water pours in. Animals with soft skins are 
easily affected when changed from fresh to salt water. Frogs 
die soon, and, as they breathe by means of lungs, it follows that 
it is entirely from osmosis, or absorption by the skin, and prob- 
ably our catfishes (S7/uridz) would not stand the change well, 
although there are two marine species (4lurichthys marinus and 
Aritopsts milbertt) on our coast. 
I am informed by Professer G. Brown Goode that sting rays 
(Zrygon centrura) are found in Lake Harney on the headwaters 
of the St. John’s River, in Florida, while the following species 
are often found in the river in pure fresh water above Jackson-
