from Professor Schmid's own collection. The muschelkalk 

 saurians of Jena were mostly of small dimensions ; but one 

 rib bespeaks a large animal. The collection contains the 

 humeri, almost the most important bone, of eight smaller 

 species, belonging to more than one genus, and the large rib 

 indicates a ninth species. Formerly I knew no humerus 

 from the muschelkalk in which the foramen for the passage 

 of the ulnar artery was wanting ; but this is the case in one 

 of the Jena bones, a circumstance hardly accidental, as the 

 bone otherwise indicates a peculiar species. A humeral bone 

 in the collection of Count Miinster also shews the existence 

 of another species, so that there are at least ten saurians in 

 the muschelkalk of Jena ; and among these humeri there is 

 scarcely one that agrees with the bones from Upper Silesia 

 or other localities in this formation. The coracoid bones in 

 Schmid's collection, belong to six species, now others are 

 found in that of Count Miinster, and this bone in the large 

 species is still wanting ; so that the coracoid bones from Jena 

 also point to the existence of nine species, most of them dis- 

 tinct from those of other districts. These collections con- 

 tain the scapulae of four small species, the femoral bones of 

 three species, and the pelvic bones of at least four species ; 

 all, as well as the small vertebrae, shewing no complete agree- 

 ment with tlie bones from Upper Silesia or other countries. 

 The teeth resemble those of the Nothosaurus. Labyrintho- 

 donts as yet are entirely wanting. Besides these, there has 

 been found, in the bone-beds of the muschelkalk of Wogau, the 

 humerus of two species, but not distinct from those of Jena ; in 

 the Wellenkalk (lower muschelkalk) of Lobedaburg, a tooth 

 of a small species, formed like that of the Nothosaurus ; in the 

 bone breccia of the muschelkalk of Keilhau, near Rudolstadt, 

 vertebrae of a very small species ; in the terebratula lime- 

 stone of Zwetzen, a bone of the pelvis ; in the highest beds 

 of the muschelkalk at Mertendorf, three leagues from Jena, 

 a humerus ; and in the Keuper limestone of Vieckberg, near 

 Apolda, a large nothosaurus-like tooth. 



The fishes from this district, with those from Querfurth 

 and from Upper Silesia, will be described by me in one of 

 the early numbers of the " Palceontographica'' the plates 

 being already lithographed. Besides scales, and an unim-
