even in that all the hairs are grey at the base. Sundevall's 

 macroJepis, also from Koseires, must resemble the present 

 species very closely in general colouring. He describes it as 

 " Supra fulvescenti-murinus, lateribus magis flavescens, sub- 

 tus albus, limite definito." The dimensions he gives, how- 

 ever — viz. : hind foot 27 and length of skull " ad suturam 

 posticam ossis transversi 32 mm.," — indicate a markedly 

 larger animal, while the character on which the name is based, 

 viz. the size of the caudal scales, is certainly not found in 

 the present animal, in which these scales are less than half the 

 size of those in macrolepis.
