Remarks. — From its nearest geographical ally, Pitymys 

 duodecimcostotun, this species is at once distinguishable by its 

 much smaller size, a character in which it resembles the small 

 Iberian forms rtlated to P. lusitanicus. From these latter it 

 differs, however, in the conspicuously projecting upper 

 incisors and very narrow interorbital region.
