394 THE ZOOLOGIST. 
of two Great Auks’ eggs which are preserved in the Museum of 
Science and Art, Edinburgh, and a coloured chart purporting to 
show the supposed distribution of Alca impennis (80 far as can 
now be ascertained), its breeding-stations, and localities where 
specimens of the bird have been procured. 
There are, unfortunately, several errors in this chart, owing 
to its having been prepared before the letterpress was printed, 
and of which the author himself became aware when too late to 
make any alterations. The necessary corrections, however, are 
pointed out in a few pages of ‘‘ Remarks” following the Index, 
so that the reader may with a little trouble inform himself of the 
true state of the case. 
European Butterflies. By W. F. pp Vismus Kang, M.A., M.R.1.A. 
Post 8yo, pp. xxxiii. 184, pls.20. London: Macmillan & Co. 
1885. 
Tu1s work is intended to meet the requirements of tourists 
more fully than any previous English publication on the same 
subject; and the author even ventures to hope that it may 
attract new disciples to the study of Entomology. Mr. Kane has 
had considerable experience in collecting in Switzerland, but 
whether he has succeeded in producing a book which will really 
be so useful as he hopes is another question. 
The volume commences with a rather long Introduction, in 
which the author expatiates on the delights of collecting; and 
adds some practical hints for the capture and preparation of 
specimens, explanations of technical terms, and remarks on 
localities, variation, &c. On p. xxv. he speaks of the latent 
tendency of certain butterflies to occasionally recur to a blanched 
Arctic type, as seems to be the case with such of the Coliide as 
inhabit temperate or northern latitudes, and the females of which 
frequently present an albino form. But as the white form of the 
female is more abundant in the South African C. electra than in 
many species which inhabit colder countries, and even the Helice 
form of C. edusa is commoner in Southern than in Northern 
> 
Europe, it seems very doubtful whether the white form of Colias — 
can be regarded as having any connection with the Arctic 
Regions.
