one simple deep reentrant angle on each side, the projecting 
angles bordering them in front and behind nearly equally salient ; 
no trace of the secondary antero-external reentrant angle, which 
in #, lutescens tends to divide into two the large antero-external 
projecting angle; posterior lobe diminished or absent. Last 
lower molar with the anterior external reentrant angle about half 
the depth of the posterior one; in fuscocapillus it is quite as 
deep as the posterior one, while in éalpinus it is almost non- 
existent.

In colour this Hilobiws has a close resemblance to the Z. lutescens 
of Lake Van, but its teeth are of much simpler pattern, more 
approaching those of #. talpinus.

This appears to be the lowland coast representative of the 
ordinary plateau Hare of Persia and Afghanistan, to which the 
name of L. tibetanus should probably be applied. 
It is distinguished by its shorter fur, which is silvery whitish 
at base, with a broad black subterminal ring. In the highland 
forms the part below the black ring is slaty basally, with a 
creamy terminal half. 
The type was described from Pishin, 8.W. Baluchistan, about 
100 miles from the coast.
