Dorothy Bate — A Bone Cave on the River Wye. 100 



Remains of this field-vole have been found in the Forest Bed and in 

 fissures near Frome and at Ightham. It is no longer living in Great 

 Britain, but is the commonest field-vole of Central Europe, its range 

 extending as far as Western Siberia. 



Microtus nivalis. — Two mandibular rami, which I have compared 

 vkrith recent specimens in the British Museum, are referred to this 

 species. A third might possibly also belong to this vole, but is too 

 imperfect to admit of certain identification. At the present day it 

 is not found in Britain, but inhabits the Alps of Central Europe, 

 where it is not found at a lower elevation than 3,000 feet above the 

 sea-level. By Dr. Selys Longchamps it is said to occur in the 

 Pyrenees, and may possibly also be found elsewhere. The only 

 record of the fossil remains of this species being found in England 

 is that of Messrs. Blackmore and Alston, who doubtfully referred 

 to this species a jaw-bone found in the river deposit at Fisherton, 

 near Salisbury (P.Z.S., June, 1874). 



Evotomys ( = Microtus) glareolus. — Part of one skull and several 

 mandibular rami of the bank- vole were found in the cave earth. 

 In one or two of the rami, which belonged to immature animals, 

 the teeth had not yet developed roots. Its remains have been found 

 in the Forest Bed, in many caves, and in Pleistocene river deposits. 

 At the present day its range extends to the Arctic circle. 



Lemnms ( = Myodes) lemmiis. — Portions of five upper jaws of the 

 Norwegian lemming were found in the earth together with eight 

 lower jaw-bones, only one of which contained the full number of 

 teeth. This species is no longer found in Britain, its range at the 

 present day being confined to the Scandinavian peninsula and 

 Eussian Lapland. Its remains have been found in a cave in 

 Somersetshire and in the Ightham fissure in Kent. 



Dierostomjx torquatus. — Nearly a dozen well-preserved mandibular 

 rami of this species were found, but only a portion of one upper 

 jaw. The Arctic lemming occurs in the Pleistocene of England 

 and the Continent, but is now entirely confined to the Arctic regions. 



Ocliotona ( = Lagomys) pusilbis. — Portions of eight or nine skulls 

 of this species were found together with nineteen lower jaw-bones. 

 The remains of this tailless hare are interesting, as no representative 

 of the family is found in the British Islands at the present day. 

 This pika now only inhabits Eastern Russia and Siberia. Its fossil 

 remains have been procured from several other caves in England : 

 at Bleadon, Brixham, and Kent's Hole. 



Zepus timidus (Z. variabilis). — Portions of a skull and lower jaws, 

 both retaining teeth, are referred to this species. Remains of the 

 mountain hare have been found in several caves, in the Mendip 

 Hills, and at Knockninny and Shandon in Ireland. 



Mus sylvaticus. — Eighteen lower jaw bones and portions of about 

 seven or eight skulls are referred to this species, which is still found 

 widely distributed over temperate Europe, and extending to Western 

 Siberia and the Caucasus. Its remains have been found in tlie 

 Forest Bed and at West Runton, Norfolk. 



A great number of small limb bones, most of which probably
