 smaller size and less darkened tail.

Note. — The Spanish form of Glis has been distinguished sub- 

 specifically from the other European races. I have not seen the 

 animal, and the following account is taken entirely from the 

 original description. 



Glis glis pyeenaious Cabrera. 



1908. Glis glis pyrenaicus Cabrera, Ann. and Mag. Nat. Hist., 8th ser., i, 

 p. 193, February, 1900. 



Type locality. — Alio, Navarra, Spain. 



Geographical distribution. — Northern Spain ; exact limits of 

 range unknown. 



Diagnosis. — Similar to the typical form in all essential 

 respects, but readily distinguishable by larger skull, and strong 

 buffy tinge of back. 



Colour. — Upper parts buffy grey, the hairs being iron-grey 

 with yellowish buff ends. In the middle of the back there are 

 numerous black hairs, showing a bright metallic gloss. Under 

 surface creamy white, separated from the upper colour by a 

 narrow, ill-defined zone of pure yellowish buff extending from 

 the cheek to the hip. Tail glossy brownish grey, with the usual 

 whitish line along under side. Ears and orbital rings brown. 

 Hands and feet white ; a broad brown metatarsal patch. 



Slcull. — Like that of typical G. glis, but larger, approaching 

 that of Glis glis italicus. 



Measurements. — Type (in flesh) : head and body, 169 ; tail- 

 vertebrse, 137; hind foot, 28; ear, 16. Skull: greatest length, 

 41-5; basilar length, 33; zygomatic breadth, 24; breadth of 

 brain-case, 18; interorbital breadth, 5'5; length of nasals, 14; 

 palatilar length, 16 ; diastema, 10; upper tooth-row, 7 '5.
