SUPPLEMENTARY NOTES. 451 



individuals who, in more recent times, have been buried in such 

 convenient repositories. M. Schmerling, in his Recherches sur 

 les Ossemens Fossiles des Cavernes de Liege, expresses his 

 opinion that these human bones are coeval with those of the quad- 

 rupeds, of extinct species, found with them; an opinion from which 

 the Author, after a careful examination of M. Schmerling's collec- 

 tion, entirely dissents. 



P. 109. The Dinotherium has been spoken of as the largest 

 of terrestrial Mammalia, and as presenting in its lower Jaw and 

 Tusks a disposition of an extraordinary kind, adapted to the 

 peculiar habits of a gigantic herbivorous aquatic Quadruped. In 

 the autumn of 1836 an entire head of this animal was discovered 

 at Epplesheim, measuring about four feet in length and three feet 

 in breadth; Professor Kaup and Dr. Klipstein have recently pub- 

 lished a description and figures of this head, (P. 45],) in which 

 they state that the very remarkable form and dispositions of the 

 hinder part of the skull, show it to have been connected with 

 muscles of extraordinary power, to give that kind of movement to 

 the head which would admit of the peculiar action of the tusks in 

 digging into and tearing up the earth. They farther observe, that 

 my conjectures (P. Ill) respecting the aquatic habits of this ani- 

 mal, are confirmed by approximations in the form of the occipital 

 bone to the occiput of Cetacea; the Dinotherium, in this structure, 

 affordipg anew and important link between the Cetacea and Pachy- 

 dermata. More than 30 species of fossil Mammalia have now 

 been found at Epplesheim. 



P. 130. Mr. C. Darwin has deposited in the Museum of the 

 Royal College of Surgeons, London, a most interesting series of 

 fossil bones of extinct Mammalia, discovered by him in South 

 America. I learn from Mr. Owen " that these include two, if not 

 three distinct species of Edentata, intermediate in size, between 

 the Megatherium and the largest living species of Armadillo 

 {Dasypiis Gigas, Cuv,,) all similarly protected by an armour of 

 bony tubercles, and making the transition from the Megatherium 

 more directly to the existing Armadillos, than to the Sloths. A 

 still more interesting fossil, is the cranium of a quadruped, which
