276 AMERICAN FISHES. 
Russia and Siberia, but does not enter those of the Trans-Caucasus and 
the Crimea. On the south it enters Roumania, and has been found in the 
Lake of St. Stefanos, near Constantinople, in the lagoons of Venice, in 
Switzerland and France, bat not in the Iberian peninsula. 
It is found in all parts of Germany, not only in the high mountain 
region, but along the sea-coast of Northern Germany, and even close to the 
shores of the Baltic. The highest vertical distribution on the northern side 
of the Alps is in the Tyrolean Lake of Halden, 3,618 feet. On the 
south, it occurs in certain lakes of the Tyrol, and in the Lake of Reschen, 
4,637 feet, which is apparently the loftiest point of its distribution. In 
Switzerland, according to Tschudi, it ranges to 3,398 feet. 
The climate of England and Germany seems suited to its best develop- 
ment, and its persistence in low latitudes will probably be found to be due 
to a special adaptability for hybernation. 
The Muskellunge, Zsox nodbilior, is the rival of the Pike in size and 
vigor, but is very limited in its geographical range, occurring only in the 
Great Lake region of America, and in the St. Lawrence River.* It is 
very like the Pike, but has a head proportionally somewhat larger, and its 
color is markedly different. In general hue, it is dark grey, with silvery 
lustre, belly white, sides dotted with round, blackish and brownish 
blotches, and the fins flecked with black. The Pike on the other hand has 
its markings white or yellowish, upon a darker background of green, dark 
grey or brown ; in European examples the lighter markings are often con- 
fluent and band-like. 
THE CHAIN PICKEREL, 
The “ Pickerels,’’ of American nomenclature, are three in number, and 
* It has frequently been said in print that Muskellunge were introduced into a pond near Bellow’s Falls, 
Mass., in 1838, and that they have since escaped into the Connecticut, where they have become abundant. 
This is a great mistake. I have examined several of these would-be Muskellunge from the Connecticut, but 
all of them proved to be overgrown Pike. ‘This species probably does not occur in the Connecticut.
