the nasals are more bent downward in front, the dorsal profile 

 being thus made faintly convex throughout. Though even more 

 flattened than in P. subterraneus capucinus, the brain-case is as 

 long relatively to its breadth as in true subterraneus. Auditory 

 bullae larger than in P. subterraneus though not peculiar in form. 



Teeth. — The teeth resemble those of Pitymys subterraneus, 

 except that the third inner re-entrant angle of m 3 is so shallow 

 that the terminal loop is essentially straight, its main axis 

 directed backward and slightly outward, its inner border with a 

 short, blunt, projecting point somewhat behind middle. 



Measurements. — Type (adult female) : head and body, 88 ; 

 tail, 32 - 5; hind foot, 14 - 5; ear, 8 - 5. For cranial measure- 

 ments see Table, p. 761.

Type locality. — Terres-plaines, near Bareelonnette, Basses- 

 Alpes, France. 



Geographical distribution. — South-western Alps ; limits of 

 range not known. 



Diagnosis. — In general similar to Pitymys subterraneus, but 

 colour differing in a strong buffy suffusion of the entire pelage, 

 particularly noticeable on ventral surface ; feet greyish white in 

 evident contrast with colour of back. 



Colour. — Upper parts a light wood-brown, sometimes tinged 

 with raw-umber, faintly grizzled with greyish and black ; on 

 sides the wood-brown becomes lighter and more buffy, passing 

 rather abruptly into colour of belly ; underparts light ochraceous- 

 buff irregularly darkened by the appearance at surface of slaty 

 under-colour, particularly on chin and throat ; feet scantily 

 clothed with silvery greyish white hairs, the dorsal surface 

 of foot strongly contrasted with back ; tail obscurely bicolor, 

 brownish above, whitish below. 



Skull and teeth. — The skull and teeth resemble those of 

 Pitymys subterraneus, but the dorsal profile of the brain-case is 

 somewhat less flattened, and the molars are usually more robust, 

 particularly the posterior maxillary tooth. The terminal loop of 

 this tooth shows a tendency to assume the short, abruptly 

 rounded form characteristic of P. multiplex. Inner border of 

 posterior triangle of m 2 with a tendency to develop an evident
