The Seal of the Severn, which Professor Nilsson regarded first as 

 P. anneUafa and then as P. Grcenlamlica, Mr. Ball thinks, from its 

 small size and the form of the intermaxillarj' bones, is neither, and

This species is only known from some sldns and three fragments 

 of skulls in the Leyden Museum, which were sent to me for com- 

 parison by the energetic Curator of the Leyden Museum. 



The fragments of skulls above referred to consist of the face-bone 

 and the lower jaws of three specimens ; the most perfect specimen 

 has part of the orbit and the upper part of the brain-case attached 

 to it. They are all from very young specimens, of nearly the same 

 age ; and, unfortunately, the most perfect one is without the hinder 

 portion of the palate, so that one cannot make sure that it has the 

 same form of the palatine margin that is found in Pagomys ; but 

 the part of the side of the palate that is present, when compared 

 with the same part in Pagomys, leads one to think it most likely to 

 be of the same form as in that genus. 



The general form and size of the face, and the form of the teeth, 

 are very similar to those of a skull oi Pagomys foetichis of the same 

 age. It only diflfcrs from the latter in the lower jaw being rather 

 shorter and broader, in the grinders being larger, thicker, and rather 

 closer together, in the central lol)e of the grinders being consider- 

 ably larger, thicker, and stronger, and in all the lobes of the grinders 

 being more acute. The lower margin of the lower jaw is dilated
