possessing dermal structures of vascular dentine, as a member of the 
Selachian order ; and the results of M. Brongniart’s researches upon 
the exquisite examples of Plewracanthus Gaudryi will be anxiously 
awaited, on account of the valuable new light they are destined to 
shed upon such questions.

(F\HE fossils described by Dr. White were collected some years 
since by the Brazilian Geological Survey under the direction 
of the late Professor Hartt, from low-lying rocks of sandstone, 
limestone, and shale, occurring in several disconnected areas 
bordering the Brazilian coast, from the mouth of the Amazon 
southwards. These rock-basins are open towards the sea, but land- 
wards are bounded by higher ridges of crystalline, and probably 
Paleozoic, strata. Some of the deposits in the neighbourhood of 
Bahia are of freshwater origin. Both marine and freshwater beds 
are referred by Dr. White to a Cretaceous age, since the majority of 
the typical fossils from them are characteristic of this period, and 
some are identical with undisputed Cretaceous fossils of other 
regions. But with these fossils occur others of a distinct Jurassic 
aspect, though not specifically identical with any known Jurassic 
Species, and, again, these are mingled with Gasteropods belonging 
to Fusus, Murex, Phorus, etc., which, if occurring alone, would have 
been referred to the Tertiary period. Judging by the Mollusca, the 
author finds this Brazilian fauna more nearly related to the 
Cretaceous fauna of Southern India than to any other yet known, 
and next after this, it approaches the fauna of the Gosau beds in the 
Tyrol. The freshwater Mollusca from the Bahia beds are likewise 
peculiar, since the species (of which 11 are described) belong to 
recent types. 
There are 82 species of Conchifera (Lamellibranchiata) described, 
most of them new; the best represented families are the Ostreeide, 
Limide, Pteriide, Arcide, Crassatellide, Cardiide, and Anatinidee. 
Of Gasteropoda, 91 species have been determined, 77 of which are 
regarded as new; the Naticide, Cerithiidw, and Fasciolariide are 
the most numerously represented families. A single new species of 
Polyzoa, Lunulites pileolus, closely resembles the L. annulata, Stol., 
from the Cretaceous of Southern India. There are 13 species of 
Cephalopoda, which, with the exception of a form of Helicoceras and 
one of Nautilus, belong to the Ammonitide. Fourteen species of 
Echinoderms are described, with one exception they are regarded 
as new. 
All the new species, and some others as well, are carefully 
illustrated in the accompanying plates, and a good index is
