PITYMYS 785 



animal as occurring at Geneva.* All recent attempts to redis- 

 cover the species in Switzerland have, however, led thus far to 

 no result. A specimen in the United States National Museum 

 labeled Geneva, Switzerland, was received in 1857 from the 

 late H. de Saussure. 



Geographical distribution. — Mediterranean coast region of 

 France ; northward to western Switzerland ? Limits of range 

 unknown. 



Diagnosis. — Similar to Pitymys ibericus, but skull with occiput 

 more obliquely truncate, so that condyles are plainly visible 

 when skull is viewed from above ; interparietal narrowly ligulate 

 instead of broadly ligulate or lozenge-shaped. 



Colour. — As in P. ibericus centralis. 



Slcull and teeth. — Except for the peculiarities already noted 

 the skull so closely resembles that of Pitymys ibericus as to need 

 no detailed description. Teeth as in P. ibericus. 



Measurements. — Four adults from the vicinity of Marseilles, 

 France (skins): tail, 25, 26, 26 and 27; hind foot, 16-4, 16 '6, 

 16 • 6 and 16 • 8. For cranial measurements see Table, p. 790.

1909. Pitymys provincialis Miller, Ann. and Mag. Nat. Hist., 8th ser., m, 



p. 420, May, 1909. Type in British Museum. 



1910. Pitymys provincialis Trouessart, Paune Mamm. d'Europe, p. 191. 



Type locality. — Saint-Gilles, Gard, France. 



Geographical distribution. — At present known from a few 

 localities in southern France (departments of Gard and Var). 



Diagnosis. — Size small (hind foot about 14"6 mm.; condylo- 

 basal length of skull, 22-6 to 23 mm. ; upper tooth-row, 5-0 to 

 5 ' 2 mm.) ; skull essentially as in Pitymys duodecimcostatus, except 

 for its much smaller size ; auditory bullas very small and flat. 



Colour. — Upper parts a light wood-brown, becoming paler and 

 more cream-buff on sides ; under parts a light grey formed by the 

 blending of slate-grey under colour with creamy white of hair- 

 tips ; feet soiled whitish ; tail whitish throughout, the upper 

 surface sprinkled with brown hairs. Young ecru-drab faintly 

 tinged with wood-brown, the underparts and feet dull greyish. 



Skull and teeth. — The skull of Pitymys provincialis is imme- 

 diately distinguishable from that of Pitymys duodecimcostatus, 

 its only near geographical ally, by its exceedingly small size, a 

 character in which it essentially agrees with P. lusitanicus and 

 the related small species of the Iberian Peninsula. From 

 these it differs in the conspicuously projecting upper incisors 

 and the very narrow interorbital region. Brain-case unusually 

 deep relatively to length of skull, its outline when viewed from
