850. A cast of the symphysis and part of the left ramus of the same lower jaw 



of the leptorhine Rhinoceros. This fragment demonstrates the short- 

 ness of the symphysis characteristic of the species, by which it approxi- 

 mates the two-horned Rhinoceros of the Cape, and differs from the 

 tichorhine Rhinoceros of Siberia. The fourth molar tooth is entire and 

 in situ. Presented by John Brown, Esq., F.G.S. 



851. A cast of the symphysis of the lower jaw of a younger specimen of Rhi- 



noceros leptorhinus, including three of the anterior molars of the left side. 

 From the freshwater deposits at Clacton in Essex. 



Presented by John Brown, Esq., F.G.S. 



852. A cast of a fragment of the left superior maxillary bone of the Rhinoceros 

 leptorhinus, including the penultimate molar tooth. 



From the freshwater deposits at Clacton in Essex, 



Presented by John Brown, Esq., F.G.S. 



853. A fossil fragment of an upper jaw with a molar tooth of probably the same 



species of Rhinoceros, from the same stratum and locality. The teeth in 

 both specimens closely correspond with those of the existing one-horned 

 Rhinoceros of India. 



Presented by the Rev. E. Everest, M.A. 



854. A fossil fragment of the left ramus of the lower jaw of a Rhinoceros, with 

 portions of two molar teeth. 



From the tertiary formations of the Sub-Himalayan district, India. 



Presented by the Rev. E. Everest, M.A.

tichorhinus : the summits of the enamelled ridges of the crown had just 

 begun to be abraded. 



From the cave at Kent's Hole, Torquay, Devon. 



Presented by Gerard Smith, Esq. 



856. The crown of the antepenultimate or fifth molar, right side, upper jaw,
