 p. 189. 



Type locality. — Forest of Bouconne, Gers, France. 



Geographical distribution. — Lowlands of south-western France 

 from Dear base of Pyrenees to the Garonne. Limits of distribu- 

 tion not known. 



Diagnosis. — Like Pitymys pyrenaicus pyrenaicus, but colour of 

 upper parts with a decided cast of buffy or pale wood-brown, 

 much as in P. savii. 



Measurements. — Type (adult female) : head and body, 93 ; 

 tail, 26 ; hind foot, 15 ; ear, 8. Average and extremes of five 

 adults from the type locality : head and body, 96 (93—104) ; tail, 

 25-6 (23-29); hind foot, 15-4 (15-16); ear, 7 -7 (7-9). For 

 cranial measurements see Table, p. 775. 



Specimens examined. — Fifteen, from the following localities in south- 

 western France : Forest of Bouconne, Gers, 14 ; Cadillac, Gironde, 1

PITYMYS PLANICEPS Miller. 



1908. Pitymys planiceps Miller, Ann. and Mag. Nat. Hist., 8th ser., I, 



p. 203, February, 1908. Type in Lataste Collection. 

 1910. Pitymys planiceps Trouessart, Faune Mamm. d'Europe, p. 190. 



Type locality. — Bareges, Hautes-Pyrenees, France. 



Geographical distribution. — Known only from the type 

 locality. 



Diagnosis. — Size about as in Pitymys subterraneus (condylo- 

 basal length of skull, 23 mm.) ; skull more flattened and depressed 

 than in any other known European member of the genus, the 

 dorsal profile nearly straight from posterior extremity of nasals 

 to back of interparietal ; teeth as in P. savii and P. pyrenaicus. 

 External characters not known. 



Skull and teeth. — In general outline as viewed from above 

 the skull resembles that of Pitymys savii in its rather short 

 rostrum, broadly spreading zygomatic arches and squarish brain- 

 case (length to back of interparietal equal to breadth over 

 zygomatic roots). Laterally and posteriorly it suggests P. sub- 

 terraneus, but with the normal characters of the species carried 

 to the extreme. The dorsal profile is essentially straight from 

 posterior extremity of nasals to back of interparietal, though 

 there is a faint concavity in interorbital region and a slight 

 convexity at middle of brain-case. Interorbital region about as
