Subgenus Dichobune. 



1118. The cast of a portion of the right ramus of the lower jaw of the Dicho- 

 bune cervinum, Owen. This specimen, besides being larger than the cor- 

 responding part of the Dich. leporinum of Cuvier, differs in the form of 

 the ascending ramus of the lower jaw, whereby it approaches nearer to 

 the true Anoplotherium. 



From the Eocene freshwater deposits at Binstead, Isle of Wight. 



Presented by S. P. Pratt, Esq., F.G.S. 



The original of this cast is figured, as belonging apparently to a spe- 

 cies of Moschus, in the 'Geological Transactions,' vol. iii., 2nd Series, 

 1830, p. 151, where, the strata from which the fossil was derived are 

 described as follows : — 



" The quarries at Binstead are, as is well known, situated in the 

 lower freshwater formation, and consist of alternating beds of compact 

 siliceous limestone, sand, and whitish shelly marl, composed almost 

 entirelv of comminuted freshwater shells. The marls are more or less 

 indurated, and form several distinct beds separated by thin seams of 

 clay, the lower of which contain the principal part of the fossil remains 

 observed, although indications of the same may be seen in all the beds. 

 These remains consist of numerous fragments of bones, scales and teeth. 

 Most of the fragments of bone have been rounded, and they are generally 

 so much injured as to make it difficult to class them. One specimen, 

 however, appears to be the head of a humerus, another a bone of a foot, 

 both probably belonging to the Pachyderniata above mentioned, as they 

 were found in connexion with the teeth. The greater number of the 

 bones may be identified with those of the freshwater Turtle, consisting 

 principally of remains of the carapax ; and two genera at least, the 

 Emys and Trionyx, have been observed, corresponding with those 

 described by Cuvier as found in the Paris basin. Of the teeth, one is a 

 molar of Palceotherium magnum, another agrees with the first molar of 

 Palaotherium minimum, and the third is apparently part of a molar of 

 Anoplotherium commune?
