. SKELETON OF MEGATHERIUM CUVIEKI vel AMERICANTJM. This was 

 modelled from the original separate bones ; some of which are in this 

 collection, and others in the Hunterian Museum of the Royal College of 

 Surgeons. It is twelve feet long, and eight feet high. The annexed 

 outline (Lign. 112), is the first published representation of this inte- 

 resting skeleton, and has been drawn with great care by the eminent 

 artist, Mr. Joseph Dinkel. 1 



H. Skull and tusks, of ELEPHAS GANESA; a remarkable fossil 

 Elephant, from India; presented by Major Baker, of the Bengal 

 Engineers. 



/. Skeleton of MASTODON OHIOTICUS, or Mastodon of the Ohio, from 

 North America ; it is 9 feet 7 inches high, and 20 feet long. The tusks 

 are 7 feet 2 inches in length, and 9 inches in diameter. On the same 

 platform there are 5 bones of the fore-foot (3 carpals and 2 metacarpals), 

 nearly twice as large in linear dimensions as the corresponding parts in 

 the above skeleton, of the Elephas mei*idionalis, dug up in the brick- 

 field at Grays, in Essex. 



Under the above skeleton, is placed the model of a perfect cranium and 

 lower jaw of a very young Mastodon; the germs of the tusks are just 

 appearing : it measures 2 feet from the front of the jaw to the occiput, 

 and 1^ from the summit of the skull to the inferior margin of the lower 

 jaw. 



ON THE TOP OP THE WALL-CASES. 



A. a. A fine series of tusks of the Mammoth (Elephas primigeuius), 

 from Drift ; some of them are from the Arctic regions, and were brought 

 home by the Officers of the Expedition sent in search of Sir J. Franklin. 

 Among these is an enormous tusk curved upwards in a spiral direction, 

 which is of the extraordinary length of 12| feet : it was dug up in 

 frozen gravel on the banks of Mackenzie River. 



B. b. Bones of Mammoths from the alluvium of North America; 

 and of Elephants and Mastodons from the Sewalik Hills. 



c. Skulls of the existing Indian Elephant of the two varieties, one 

 with short, the other with long tusks. 



d. Bones of Mastodons (Mastodon Ohioticus), and Mammoths (Ele- 

 phas primigenius), chiefly of the extremities, vertebrae, &c. from the 

 alluvial deposits of North America : some of them are from Big-bone 

 Lick, others from the State of Missouri.

 1. ECHINITES, or fossil Echinoderms. An extensive suite of species 

 and genera from various formations, (at present in Table-case 1, Room V.) 

 will occupy this cabinet. The specimens are admirably arranged and 

 named, so as to be easily identified and examined. It is a most instruc- 

 tive collection for the palaeontological student, for it comprises a consi- 

 derable number of the fossil genera of this order of Radiata, viz.
