Cat gene frequencies in cities of the U.S.S.R.

Analyses of mutant gene frequencies have been completed for the cities of Armavir, Khabarovsk and Vladivostok of the U.S.S.R. These are compared with previous work and the overall picture briefly summarised and discussed. The prospects for future investigations are stressed.     

Pohlia andrewsii J. Shaw in the U.S.S.R.

Abstract

P. andrewsii appears to be widespread in the arctic regions of the U.S.S.R. and also in mountains of southern Siberia, the Altai Mountains. Except in the mountains of Central and Northern Europe the range of P. andrewsii does not overlap with P. annotina and P. camptotrachela.
