APPENDIX. 195 



" In Piedmont the pachydermatous deposit occupies a zone limited by the right bank of 

 the Po ; the sub-appenine sands, so called, on the left bank of this river, are either naked or 

 covered with beds of rolled flint, not channeled, collected by the waters from the melting of the 

 alpine snows, — in a word, from the non-fossiliferous alpine diluvial deposit." 



Skeleton. — We have thought it might be interesting to palaeontologists in this country 



to have the means of forming some notions of the character of the skeleton. These we have 



endeavored to furnish as well as time would permit ; but, of necessity, in a very limited degree. 



In fact we do not feel authorized to give more than an account of some of the measurements 



of the different bones, which are particularly and scientifically described by Professor Sismonda. 



We have therefore, to some extent, translated, and converted into English measures, the labors 



of the author; assuring, at the same time, those who feel an interest in the subject, that 



they will be much gratified in studying the researches, and examining the beautiful plates, of 



Professor Sismonda. 



Head. — The present specimen is more complete in this respect than any known, except 



that of M. Lartet at Sansans, Department of Gers. 



Occipital Vertebra.* — The best preserved part of the cranium is a large portion of the 



right occipito-temporal, which exhibits the condyle of the right side, the posterior foramen lacerum, 



the glenoid cavity, and the posterior zygomatic extremity.

* Professor Sismonda has employed the anatomical terms of the " homological system " in his description of the 

 bones of the head. 



Assenting, as we do, to the beauty and convenience of this system, we came, after much consideration, to the conclusion 

 that in the present state of the reform the received appellations would be more generally understood than those proposed, 

 and therefore adopted them in our own text. — Author's Note.
