be every reason to conclude, that the bituminization of this mass of rock* is 

 due, in a great measure, to the destruction of the large quantity of animal 

 matter contained in it ; for the coprolite itself only differs from the surrounding 

 matrix in containing a greater proportion of phosphate of lime. 



All the other mammalia hitherto found at ffiningen are llodentia ; and 

 for an account of several of them 1 refer to the works of Baron Cuvierf. One 

 specimen of these, which is in the British Museum, has subsequently been 

 figured, and named by Mr. Konig Anooema GE7iingensisl. 



Another animal of this order was brought from the quarries this year by 

 Professor Sedgwick, which M. Laurillard of the Jardin du lloi, Paris, refers 

 to Lagomys. 



Birds. 



These are considered by Blumenbach and Karg to be chiefly aquatic, and 

 according to the former they consist principally of Gralla. The latter author 

 enumerates birds of other classes,, as well as detached specimens of beaks and 

 feathers §. 



Reptiles. 



Of these the most curious is the large aquatic Salamander, described by 

 Cuvier, and of which there are several individuals ; one of which, in admirable 

 preservation, is in the British Museum. In the Carlsruhe Museum I ob- 

 served specimens of Rana and of Testudo. Besides the splendid individual 

 mentioned, p. 281. in the section of the quarries, the Testudo orbicularis? is 

 said to have occurred ||. 



Fishes. 

 The fishes of ffiningen have not yet been fully described, although Andrsea, 

 Lavater, Knorr and Scheuchzer, published and figured many genera and 

 species, comprehending lamprey, trout, pike, seventeen species of carp, &c. 

 Cuvier and Blainville doubt the accuracy of many of these identifications, al- 

 though they both allow they have not as yet seen a sufficient number of spe- 

 cimens for comparison, and the former distinctly reserves his opinions for a

§ Karg's list of organic remains is not given, because many of his specifications cannot be de- 

 pended upon. Of the specimens alluded to by him the greater number are now in the Carlsruhe 

 Museum ; others are in the British Museum, and a few are at Paris and Vienna.
