Muscaixliuidaj/A-om the Iberlaa Peninsula. 193 



With regard to the north of tlie Peninsula, GUs evidently 

 occurs there. Seoane records a specimen actually obtained 

 in the Oaabeiro woods, near Ferr(d ; two specimens from 

 Navarre exist in the Museum of Madrid, and another, from 

 San Esteban de Palantordera, Barcelona province, is pre- 

 served in the Martorell Museum of Barcelona. 



On corn))arison with true G. glis from Germany in the 

 same collection, the Navarre specimens in the Madrid Museum 

 appear to rejiresent a well-marked local form, which I 

 describe as follows : — 



Glis glis pyrenaicus, subsp. n. 



Characters. Similar to the typical form in all essential 

 respects, but readily distinguishable by its larger skull and 

 the strotig bufFy tinge of its back. 



Colour. Upperparts 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 [)ure yellowish buff extending 

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

 the usual whitish line along its underside. Ears and orbital 

 rings brown. Hands and feet white; a broad brown meta- 

 tarsal patch as usual. 



Skull. Like that of typical G.glis, but larger, approaching 

 G. italicus in this respect. 



Measurements (type in flesh). Head and body 169 mm.; 

 tail-vertebra3 137 ; hind foot (s. u.) 28; ear IG. 



Skull: greatest length 4 r5 ; 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'o. 



Hah. Navarre Pyrenees, North Spain. The specimens 

 recorded from Eerrol and Barcelona probably belong to the 

 same species. 



Type. Adult female from the neighbourhood of Alio, 

 province of Navarre. No. 1223, Museum of Natural Science 

 of Madrid. 



Remarks. This form seems to be the most western repre- 

 sentative of the grey dormouse, and opposite in size to the 

 small eastern G. g. spoliatus. Whether or not it ranges 

 southwards along the Burgos Mountains and Serrania de 

 Cuenea, as other Pyrenoau mammals do, I am not able to 

 say at present.
