salmonoide^e. 179 



The Salmo rivalis {Fauna Grcenl., p. 176), named by the Greenlanders 

 Aunardleh and Eekattoogak, if it be not the young of some of the preceding, is 

 most probably distinct from any that we have described. In the minuteness of its 

 scales it resembles S.fontinalis. It inhabits rivulets and ponds, feeds upon insects, 

 and buries itself in the mud in the winter, where it is frozen up, never visiting the 

 sea. It is only six inches long. The word Eekallook seems to be the general 

 Greenland and Esquimaux name for the trouts of the middle or smaller size.

This magnificent trout, which equals or surpasses the Common salmon in size, 

 is a denizen of all the great lakes that lie between the United States and the Arctic 

 Sea, but it does not exist, as far as I have been able to ascertain, in any tidal 

 waters. According to the report of fishermen on Lake Huron, seventeen pounds 

 is its average weight, but they occasionally capture individuals weighing sixty 

 pounds; and Dr. Mitchill states, that at Michilimackinac it has been known 

 to attain the enormous size of one hundred and twenty pounds. Such a weight 

 must, however, be very rare, for Carver, who passed a winter at Michilimackinac, 

 does not appear to have met with any at all approaching to that magnitude. 

 " One of my chief amusements," says he, " was that of fishing for trouts. 

 Though the straits were covered with ice, we found means to make holes in it, and 

 letting down strong lines, of fifteen yards in length, to which were fixed three or 

 four hooks baited with small fish, we frequently caught two at a time, of forty 

 ■pounds weight each, but the common size is from ten to twenty pounds." Particular 

 lakes in the fur countries were mentioned to us as yielding trout of sixty or even 

 ninety pounds,, but none exceeding forty pounds came under our own observation*. 

 The namaycush is the tyrant of the lakes ; no fish inhabiting the same waters can

 ellet ont la chair rouge? {Mint, de PAmirique, ii., p 58.)
