Xantusia from California, but neglected to give it a name. I propose 
that it be called X. picta.—E. D. COPE. 
Comparisons of Marriages and Births in the Different 
European Countries.—The following facts were compiled by M. 
Chervin and presented by him to the Anthropological Society at its 
recent conference at Broca. The first fact to be noted is that in respect 
to the number of marriages France falls a little below the number re- 
corded in the principal countries of Europe, as the following table 
testifies. 
Of 1000 people of both sexes, over 15 years of age, the per cent. that 
marry is as follows: Hungary, 91.6; Germany, 53.0: England and 
Wales, 52.6; Denmark, 52.0; Austria, 51.3; Italy, 50.1; Finland, 
492; Holland, 49.0; France, 45.8; Belginm, 41.9; Greece, 41.6; 
Scotland, 40.9; Switzerland, 40.8; Ireland, 23.0. 
~ But the number of marriages is only one of the factors in the prob- 
lem of the increase of population. The most important thing is the 
fecundity of these unions. Statistics in regard to births are given as 
follows: (1) Legitimate living children born of 1000 married women 
from 15 to 50 years of age—Germany, 270 ; Scotland, 269; Belgium, 
265; Italy, 251; England and Wales, 250; Austria, 250; Sweden, 
240; Ireland, 240; Switzerland, 236; France, 163. (2) Illegitimate 
living children born of 1000 unmarried women from 15 to 60 years of 
age—Germany, 265; Scotland, 199; Belgium, 198; Italy, 246 ; Eng- 
land and Wales, 121; Austria, 444; Sweden, 444; Ireland, 41 ; Swit- 
zerland, 102; France, 167. 
These lists show that in respect to legitimate births France falls 
below the other European countries, and even taking into account the
