of Talpida, in which I include the Water-moles, or Des- 

 mans (Mygale) ; the fossil differs from the common Mole 

 (Talpa), and resembles the Mygale pyranaica in the size 

 of the first true molar, which nearly equals the second, 

 and in the larger size of the three premolars ; it precisely 

 resembles the common Mole in the position of the two 

 outlets of the dental canal which are preserved in the fossil. 

 The fossil differs, however, from both the typical Moles and 

 the Desmans, not only in its larger size, but in some slight 

 modifications of the crown of the true molars ; there 

 is a minute but sufficiently obvious tubercle at the bottom 

 of the outer fissure, between the two principal cusps of 

 each molar, of which there is no trace in recent Insectivora. 

 The specific name is founded on the leading character of 

 this extinct Mole-like Insectivore, viz., its large size. 



For the knowledge of this specimen I am indebted to 

 Mr. Waterhouse, the able assistant in the Fossil Depart- 

 ment of the British Museum.
