influence of the interior heat. In the next chapter is brought to- 
gether all previous knowledge of climatic zones in Jurassic times, 
and the next treats of the characteristics of an Alpine Jura and a 
mid-European Jura. This is followed by a chapter upon the dis- 
tinguishing features of an Alpine and a Mediterranean Neocomian. 
He finally thus classifies the zo6geographical provinces of Juras- 
sic and Cretaceous times: 
T. Boreal Zone. III, Equatorial Zone. 
1. Arctic province. 1. Alpine (Mediterranean) province. 
2. Russian s 2. Crimo-Caucasic z 
3. Himalayan “ 3. South i bs 
4. Ethiopian ~ 
5. Columbian vi 
5a. Caribbean rs

Tertiary.—Numerous plant impressions, together with remains 
of Sus major, Hipparion gracile, Castor jegeri, etc., have been 
found in the lignite beds which are interstratified with the lower 
layers of the Miocene of Cerdagne, an ancient lacustrine basin on 
the southern slope of the Pyrenees. F. Fontannes writes of a 
new exposure of Miocene strata near Lisbon (Portugal), and de- — 
scribes the fossils found there, including a species of swimming- 
crab (Achelous delgadoi), the first representative of this tropical 
genus yet found in the Miocene. It occurs abundantly in the 
strata containing Venus riberroi. “ The classification and palæ- 
ontology of the United States tertiary deposits.” Under this head 
a note has been published in the number of June 12, of this jour- 
nal, on the first part of my article, “ The genealogy and the age 
of the species in the Southern Old-tertiary,” American Journal 
of Science, June, 1885. I refer those readers of Tne NATURALIST 
who are interested in this matter to the second part of this article,

Quaternary —M.Stanislaus Meunier has described a Quaternary 
flint from the valley of Loing, forty-five mm. in diameter, con- 
taining not only a movable nucleus of stone, but a quantity of 
water. Such cases are well-known among quartz or concretions 
from amygdaloid rocks, but the example is said by M. Meunier 
os to be unique among flints. The water must have come from the 
Quaternary in which the flint, itself of Cretaceous age, was 
__ lying, and must have penetrated the stone by permeating the silex.
