This species has been twice recorded by M. de Loriol-le-Fort, 

 who, in the later of his excellent accounts of the sjDecies, considerably 

 reduced its dimensions. 



In his Monograph of 1880 ^ he records the length as from 

 25 to 60 mm., and in that of 1883 ^ as from 12 to 26 mm. These 

 specimens (I 1379) from the Eocene of Abu Roash fully agree with 

 the account and figures in his earlier paper. Tlie specimens are of 

 the larger size, 57 mm. long by 41mm. broad by 34 mm. high. 

 They are nearest, among the larger species, to E. lihycus, Lor.^
