778 EODENTIA 



Diagnosis. — Similar to Pitymys lusitanicus, but skull with 

 narrower, lower brain-case ; upper incisors so slightly projecting 

 as to be scarcely visible when skull is viewed from above. 



Colour. — The colour is probably similar to that of Pitymys 

 lusitanicus, though in the only known specimens, skinned after 

 immersion in alcohol, it has a peculiar, perhaps unnatural 

 russet cast. 



Skull. — General outline of skull when viewed from above 

 essentially as in Pitymys subterraneus, the length of brain-case to 

 back of interparietal evidently more than width over zygomatic 

 roots. Whole skull more depressed than that of P. lusitanicus, 

 so that dorsal profile is much less convex, and general outline 

 viewed from the side is less strongly cuneate. Auditory bullae 

 and structure of palate as in P. lusitanicus. 



Teeth. — As in Pitymys lusitanicus, but upper incisors nearly 

 vertical, so that part of the anterior surface of teeth is invisible 

 when skull is viewed from above. 



Measurements. — Type (adult female) : head and body, 79 ; 

 tail, 30; hind foot, 13-6; ear, 76. Not fully adult male from 

 the type locality: head and body, 84; tail, 25; hind foot, 14; 

 ear, 7 ■ 5. For cranial measurements see Table, p. 788. 



Specimens examined. — Eight, all from north-western Spain.

p. 204, February, 1908. Type in British Museum. 

 1910. Pitymys pelandonius Trouessart, Eaune Mamm. d'Europe, p. 192. 



Type locality. — Silos, Province of Burgos, Spain. Altitude 

 about 3000 feet. 



Geographical distribution. — Not known at present elsewhere 

 than in the neighbourhood of the type locality.* 



Diagnosis. — Similar to Pitymys marise Major, but skull with 

 broader, less elongated brain-case. 



Colour. — The colour of the four skins examined resembles 

 that of the lighter, more wood-brown specimens of P. lusitanicus. 



Skull and teeth. — The skull differs from that of both Pitymys 

 lusitanicus and P. marise in its broader more quadrate brain-case. 

 Posteriorly the brain-case is rather low, as in P. marise, though 

 much less reduced in depth than that of P. depressus. Teeth as 

 in P. marise, the upper incisors nearly vertical. 



Measurements. — Type (adult female; : head and body, 96 ; 

 tail, 28; hind foot, 14'4; ear, 8 - 4. Adult female from Castrillo 



* Occurs among brush and shrubbery, avoiding the open fields 

 inhabited by P. ibericm.
