CABINET OF COMPARATIVE ANATOMY. 



skeletons of the humming birds. The two last 

 cases contain the tortoises, amongst which is a 

 very large specimen of the sea and also one of the 

 Indian land tortoise, the largest known at this 

 day. The series of teeth, beginning with those of 

 the horse and terminating with those of fishes, is 

 here continued and shewn in small boxes placed 

 on the tables. Above the cases we see the ske- 

 letons of four large crocodiles, and near the one 

 sent by M. Wallick are bracelets which were 

 found in the stomach of this animal, and which 

 must have belonged to an Indian woman. 



The skeletons of the reptiles, such as lizards, 

 serpents, toads, frogs, and salamanders, with 

 those of all the genera and of a great number of 

 species offish, occupy the cases in the fifth room. 

 On the top of the front cases we see the skeleton 

 of a boa constrictor, 1 5 feet long, brought from 

 Java by M. Leschenault, those of a shark and of 

 a sword-fish from the Mediterranean, and on 

 each side a series of snouts of the saw-fish, jaws 

 of several species of shark, the ray, etc. On the 

 tables in this room are the dried larynx and hyoid 

 bones of quadrupeds ; amongst which is that 

 of the simia seniculus, which is inflated like a 

 bladder : it is this peculiar form which gives the 

 voice of this animal the great extent and extraor- 

 dinary sound for which it is remarkable.
