first described by Eilenburg in 1755, and confounded in more recent 
times with the 4olodon (Crocodilus priscus, Seem.) to which it was 
referred by Cuvier in the last edition of his ‘ Ossemens Fossiles.”? It 
has since been characterized and partially figured by Dr. Jager, under 
the name of Crocodilus Bollensis; the specimen having been found in 
the lias at Boll in the kingdom of Wiirtemberg. The authour points out 
the «lifferences in its several extant parts which distinguish the skeleton of 
this animal from that of olodon, and gives it, on account of the 
extraordinary length of the bodies of its vertebre, the generic name of 
Macrospondylus. We concludes his paper by the description of some 
portions of a skeleton of the Pterodactylus macronyx of Dr. Buckland, 
found in the lias at Banz in company with an almost perfect skeleton of 
a large Saurian with a long muzzle, and with the bones of atortoise. The 
remains of the Pterodactylus are figured in the accompanying plate, 
The last paper which falls under our cognizance is entitled ‘* Testudo 
antiqua, eine in Siisswasser-Gypse von Hohenhéwen untergegangene 
Art; beschrieben von Dr. Heinr. G. Bronn.’’ It contains a full des- 
cription of a new species of fossil Tortoise from the fresh-water Gypsum 
of Hohenhéwen, made from numerous specimens that came under the 
authour’s observation in various collections. The remains are compared 
with Testudo Greca and Test. tabulata, and with the fossil species 
hitherto observed ; and are finally characterized as follows: Test. antiqua, 
“* testd lato-ovatd, antice gibbd et medio margine incisa ; squamarum 
vertebralium areis convexiusculis, muticis, obsoleté radiatim striatis, 
medio punctatis ; squamis marginalibus 24 (222), emparibus antica et 
postica e duabus connatis ortis; sterno anticé subconvexo-truncato.”’
