cusps, and differ in both these respects from the 31. musctdiis. These 

 specimens were obtained from the West Eunton Freshwater Bed, as 

 were also certain limb-bones which probably belong to the same 

 species. 



Sciurus vulgaris ? — It was Professor Oswald Heer, who first 

 noticed that some of the Fir-cones found in the " Forest Bed '* had 

 been gnawed in a manner precisely like what is known to be the 

 work of the recent squirrel, and on this authority Mi\ A. Bell intro- 

 duced the genus Sciurus into his list of Mammalia from these beds 

 (Geoh Assoc. 1871). There is a small humerus from Ostend, 

 in the Green Collection at the British Museum, which agrees so 

 exactly with that of the recent Sciurus vulgaris that there is little 

 doubt as to its belonging to that species. It is supposed to have 

 been obtained from the " Forest Bed," but there is the same doubt 

 as to its true horizon, as there was seen to be in the case of the 

 Arvicola amphibia, and therefore, a query is placed after the species. 



Insegtivora. 



Talpa. — Since the publication of Green's History of Bacton, in 

 1842, the Mole has been recognized as belonging to the "Forest Bed " 

 Fauna. The characteristic humerus has been very frequently ob- 

 tained from the Freshwater Bed at West Eunton and Bacton, and 

 jaws from the latter place are referable to the Talpa Europcea, and 

 not to the T. cceca. 



Sorex. — Prof. Owen recognized two species of Sorex from the 

 " Forest Bed," which he thought were probably S. fodiens and 

 S. remifer. Little more can be said, at the present time, than that 

 there are two species differing in size, and although it seems to 

 be desirable to refer them to the S. vulgaris and S. pygmcBUs f, this 

 change from the names given by Prof. Owen is probably chiefly 

 owing to the complex synonymy of the species, which, in 181:6, had 

 not been so carefully worked out as it has since been by Blasius 

 and Bell. 



Myogale moschata. — The lower jaw called by Prof. Owen PalcBo- 

 spalax magniis is now known to be identical with that of the recent 

 Desman of Eussia, the Myogale moschata, which is referred by 

 some writers to the genus Sorex. Several jaws and limb-bones 

 have recently been obtained from West Eunton, which confirm the 

 identity of these fossils with the recent form.
