Common crayfish : sickness and abnormities [see supra , p. 10]. 
F. T. Koppen points out the geographical distribution of the species 
of Astacus in the Russian Empire. A. Jluviatilis (Rond.) is almost 
exclusively confined to the waters, rivers, and lakes discharging into the 
Baltic ; A. pachypus (Rathke) and colchicus (Kessl.), to those of the 
Caspian and Pontic basin; A. Icptodactylus (Esch.), probably originally 
proper to the Pontic and Caspian basin, lives at present also in the 
northern part of Russia, in many rivers flowing into the White Sea or 
the Gulf of Finland, where it appears to have supplanted A. fluviatilis ; 
it was brought, in 1822, by F. J. Fetissow into the river Isset, a confluent 
Of the Tobol, and is now found rather commonly in those two rivers, 
and in the Tura, Irtysch, Tara, Om, and also in some upper part of the 
Obi, partly transferred by man, partly also spontaneously spreading up 
tho rivers, whereas formerly no crayfish was found in Westorn Siberia.
