in the same state as the frog, and measuring two inches and seven or 
eight lines inlength. Its skeleton is compared with that of the common 
Salamander, from which it differs in various particulars. ‘* The greater 
breadth of its head distinguishes it from the Water Salamanders; and 
from all the known species of Land Salamanders it differs in the structure 
of its skull, and in the very backward position of its orbits, by which 
it approaches the frogs on one side and the Proteus on the other.” 
Along with this Salamander occurs the Triton Woachicus, Goldf., a small 
species referred to that genus on account of its narrow oval skull, and 
measuring somewhat more than two inches in total length. It differs 
from the living species of its genus in the structure of its skull, the 
peculiarities of which are described and figured. 
Lastly the author figures an impression representing two fragments of 
a spirally rolled snake-like body, to which he gives the name of Ophis 
dubius, doubting whether they belong to a snake ora serpentiform fish, 
It is a curious specimen and well deserves the attention of fossil zoologists. 
The “ Beitrage zur Petrefactenkunde”’ of Dr. Von Meyer is also a 
miscellaneous paper on fossil remains of considerable extent and high 
importance. It is divided into four sections, the first of which contains 
<* a description of the Orthoceratites striolatus, with remarks on the 
structure and occurrence of certain polythalamous fossil Cephalopoda ; 
and a description of Calymene equalis.” This part of the memoir 
commences with a detailed examination of the structure of Orthoceratites 
and of the other fossil Cephalopods, and especially the Belemnites, to 
which they are related. In the course of his examination several new 
facts are brought to light; and additional means of regulating the 
arrangement of the shells, and of determining the station and characters 
of the animals by which they were formed, are furnished to the zoologist, 
The new species described is from the orawwacke schist of Herborn; its 
characters are given with great minuteness, and figured in two plates 
with much detail. A general essay on the strata in which Orthoceratites 
have hitherto been found, and on the species peculiar to each, together 
with some notices of other fossil shells occurring in the same localities, 
forms the subject of the succeeding chapter, and is continued in an
