MASTODON AMERICANOS, Cuvier. 



(The " Shawangunk Skull ") 



A large public museum, for which we are now mounting a 

 Mastodon skeleton, has asked us to find a sale for a cast of 

 the head of this species which the actual skeleton will replace, 

 as well as for another large cast which is crowded out through 

 lack of floor-space. The former is figured above, and the 

 latter is our restoration of the giant tortoise, Colossochelys 

 atlas, from the Pliocene of the Siwalik Hills, India. Both 

 of these casts we furnished to the museum a few years ago. 

 They are to-day in excellent condition, but in order to effect 

 an immediate sale are offered at a reduced price. Full details 

 will be sent to anyone interested in their purchase. 



Circular 59, just issued, lists casts of fossil mammals 

 and birds, suitable for museums and colleges. Send for 

 complete list of our circulars in all departments of natural 

 history.
