alkaline carbonates in the ashes of coal is a natural consequence 
of the excess of sulphate of lime always present in the ashes. 
Johann Kusta describes Anthracemartus krejcit, a new Arachnid 
from the Carboniferous of Bohemia. H.B. Genitz describes Krer- 
scheria, a pseudo-scorpion. 
‘an.—An impression of a terrestrial shell (Dendropupa 
walchiarum Fischer) has been found in the Permian beds of Saone 
et Loire. This is the only terrestrial mollusk of Carboniferous 
age that has yet been found on the European continent. Dendro- 
pupa vetusta was described in 1853 by Dawson, from trunks of 
Sigillaria in Nova Scotia, and several other Devonian and Car- 
boniferous pulmonates have since been found in America. 
Tertiary.—Johann Kusta enumerates three species of Hyopo- 
tamus and two of Anthracotherium from the Hempstead beds of 
the Isle of Wight-—W. Davies has verified the occurrence of 
Hyaenarctos in the Miocene strata of Pikermi near Athens. 
W. Davies (Geol. Mag., Oct., 1884) describes Viverra hastingsie 
and remains of two other carnivores from the Eocene fresh-water 
beds of Hordwell, Hampshire. J. S. Gardiner describes (Geol. 
Mag., Dec.) six species of Aporrhais, all belonging to an ancestral 
type of the recent A. pes-pelecant, from the Eocene of Great 
Britain. R. Lydekker describes a new species of Merycopota- 
mus (M. nanus), from examples in the British museum. 
Ouaternary.—Entire skeletons of the cave hyzena are rare, for 
these animals devoured the bones of their own as well as of other 
species. Recently M. F. Regnault, of Toulouse, has descended 
into a cavity twenty meters deep in the grotto of Gargas, Hautes 
Pyrenees, and has found entire skeletons of hyzenas, bears and 
wolves, the position being such that the hyenas could not get at 
the bones to devour them. From examination of these bones, 
M. Alb. Gaudry believes that A. spe/ea is but a variety of ZH. 
crocuta, 
MINERALOGY AND PETROGRAPHY.' 
Wapswortu’s LITHOLOGICAL STUDIES, Part 17—This hand- 
somely printed quarto volume of over two hundred pages and 
lates, at first glance promises, both from its title 
and general scope, to be a most valuable addition to the literature 
of petrography ; nevertheless a careful study of its contents fails 
to discover as much that is new and useful’ as was at first ex- 
pected. The work aims to be an exhaustive and critical revision | 
of all the petrographical work hitherto accomplished as well as 
an attempt to rearrange the same in accordance with the author’s
