drate of iron, renders them ornamental. The medullary cavities are, 

 in many cases, filled with pyrites, and in others with pm'e white cry- 

 stallized carbonate of lime. The greater part of the fossils, already 

 procured, is from the deposit in the Kalowala Pass ; and as my collec- 

 tion is not only large, but abundant in different genera, the number 

 already found in such a limited space, indicates the great variety of 

 animal remains, which a diligent and extensive search may produce. 

 Teeth, and the more isolid part of the bones, are found in the greatest 

 quantity. Most of the former are perfect, and as sharp in their outline 

 as when the animals existed ; and even in the fragments, the sharpness 

 of the fracture proves, that they were quietly deposited in the sedi- 

 ment in which they are found. The following is a list of the fossils al- 

 ready discovered in the marl : — 



Mammalia. 



Pachjiermata Teeth, and the remains of a species of Anthracotlierium, 



Carnivora Genera doubtful ; but some of the teeth correspond 



with the third incisor of the bear. 



Rodeniia E.at, and a small variety of castor. 



JRuminantia Deer, several varieties, and one molar of a very small 



species. 



Solipeda , ....Horse, one incisor, and one molar from the right side 



of the upper jaw : they exhibit a peculiarity in the 

 form of the enamel flexures. 



Reptilta. 



Crocodilia Gharidl. {Gavial of natmalists.) Teeth and bones 



in abundance. 

 Crocodile, Teeth, in great abundance, fragments of 



the osseous plates, vertebree, and other bones. 

 Chelonia Emys, Fragments of the plates of the back very per- 



fect ; also ribs, with the attached osseous part of 

 the buckler. 



Tryonix. Ditto, ditto. Some marked differences ia 

 the form and position of the rugous surface of the 

 fragments of the buckler, may hereafter point out 

 a variety of species. 



Pisces. 



VtrtehrcB and Scales— The latter doubtful.
