first described by Eilenburg in 1755, and confounded in more recent 

 times with the jEolodon [Crocodilus prisons, Soera.) to which it was 

 referred by Cuvier in the last edition of his " Osseniens 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 auihour points out 

 the differences in its several extant parts which distinguish the skeleton of 

 this animal from that of jEolodon, and gives it, on account of the 

 extraordinary length of the bodies of its vertehrts, the generic name of 

 Macrospondylus. He 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 a tortoise. The 

 remains of the Pterodacti/lus are figured in the accompanying plate. 



The last paper which falls under our cognizance is entitled " Testudo 

 antiqua, eine in Siisswasser-Gypse von Hohenhdwen 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 Hohenhdwen, made from numerous specimens that came under the 

 authour's observation in various collections. The remains are compared 

 with Testudo Grceca and Test, tabulata, and with the fossil species 

 hitherto observed; and are finally characterized as follows : Test, antiqua, 

 " testa lato-ovatd, antice gibbd et medio margine incisa ; squamarum 

 vertebralium areis convexiusculis, muticis, obsolete radiatim slriatis, 

 medio punctatis ; squamis marginalibusli {22?), imparibus antica et 

 postica e duubus connaiis ortis; sterno antice subconvexo-truncato.^^
