Family Potamogalidse : — Three papillae in Poiamogale velox. 

 Family Chrysochloridie : — Three papillte in all species of 



Ghrysochloris, 

 Family Talpidse :— Two papillae in all species of Talpa, Myogale, 



Condykii'a, Scapunus and Scalops. 

 Family Soricidse : — Two papilla; in all species of Sorex. 

 Three papilloe in Rhynchocyon. 



The papillae are round or oval on plan, and cylindrical or 

 conical on elevation. The surface is smooth or granular, and 

 there may be a small central depression. The fossa and vallum 

 are well-marked. Carlier (3) showed that the papillae in Erinaceus 

 europceus contain .serous glands and ganglion cells, and their 

 connective-tissue cores are very cellular. The ducts of these 

 serous glands open along with those of the serous glands within

the base of the tongue. The only other Mammals, so far as I am 

 aware, in which there are glands within the vallate papillae are 

 the Chiroptera. 



Fungiform Papillce : — These papillae are never very numerous, 

 but more are present in Erinaceus and Ghrysochloris (text-fig. 55) 

 than in any other genus. It may be difficult to detect them, for 

 they are usually very small. Dobson (7) points out, however, 

 that they are prominent in Gyinnura rafflesii and Ghrysochloris 

 villosa. They may be composed entirely of epithelial cells, as in 

 Erinaceus, or they consist of both epithelial and connective-tissue 

 elements. 



Cortical Fapillce : — In all species the conical papillae are 

 numerous and closely packed. They are usually very small on 

 the oral part of the dorsum; and they are usually small on the
