pitymys NEBRODENSIS Mina-Palumbo.

 p. 187. 



Type locality. — Le Madonie, Sicily, 



Geographical distribution. — Sicily. 



Diagnosis. — Similar to Pitymys savii, but skull with deeper, 

 more elongate, less flattened brain-case, and more evidently 

 convex dorsal profile ; mesopterygoid space relatively wider than 

 in P. savii. 



Colour. — The colour does not differ appreciably from that of 

 the related species. 



Skull. — The general form of the skull as viewed from above 

 is much as in Pitymys savii ; length of brain-case about equal to 

 breadth over roots of zygomata. In lateral and posterior view, 

 however, it is seen to be decidedly deeper, more as in ordinary 

 members of the ibericus group. 



Teeth. — Thj teeth are essentially as in Pitymys savii, though 

 the posterior upper molar is usually not so long owing to the 

 excessive shortening of the posterior loop. In one specimen* 

 among the ten skulls examined, the first outer triangle is 

 opposite the inner triangle, the two together forming a single 

 transverse loop as in the ibericus group. The length of the outer 

 triangle is, however, not reduced, so that the resemblance to 

 ibericus is only superficial. 



Measurements. — Adult male from Castelbuono, Sicily : head 

 and body, 100; tail, 29; hind foot, 16; ear, 10. For cranial 

 measurements see Table, p. 774. 



Specimens examined. — Nine, all from the island of Sicily (B.M. and 

 .U.S.N.M.).

PITYMYS PYRENAICUS de Selys-Longchamps. 

 (Synonymy under subspecies.) 



Geographical distribution. — Pyrenees (known from the French 

 side only) and region to the north as far as the Garonne. Limits 

 of range not known. 



Diagnosis. — Related to Pitymys savii and P. nebrodensis ; 

 general form of skull somewhat intermediate between that of the 

 Italian and Sicilian species, but mesopterygoid fossa decidedly 

 narrower.
