Pitym)js ihericus regulus, subsp. n. 



Type. — Adult female (skin and skull). Collected on north 

 slope of the Alhambra Hill, Granada^ Spain, December 22, 

 1906, by G. S. Miller. Original number 7441. 



Characters. — Similar to Pitymys ihericus centralis, but 

 smaller (hind foot 15 to 16 mm. instead of 16 to 17'2 mm.), 

 and with very small, narrow molars. 



Measurements. — Type. Head and body 100 mm. ; tail 26 ; 

 hind foot 16; ear from meatus 9. Skull : condylo-basal length 

 25 ; zygomatic breadth 15 ; interorbital constriction 4*0 ; 

 occipital breadth 12 ; occipital depth '6-2 ; palatal depth 8*0; 

 nasal 6-4 ; diastema 8'0 ; mandible 16-6 ; maxillary tooth- 

 row 5"4 ; mandibular tooth-row 5'4. 



Specimens examined. — Seven, all taken in the almond 

 orchard on north slope of the Alliambra hill. 



Remarks. — This local race of Pitymys ihericus is at once 

 recognizable by its unusually small molars, the actual struc- 

 ture of which, however, shows no peculiarities. In size of 

 teeth it represents the opposite extreme from the large form 

 occurring in the valley of the Baul, only about 70 km. east 

 of Granada, and also in the Guadalquivir drainage-basin. 



Pitymys ihericus fuscus, subsp. n. 



Type. — Adult male (skin and skull). Collected on the 

 Dehesa de Valencia, Valencia, Spain, March 7, 1907, by 

 Norberto Gonzalez. Original number 131. 



Character's. — Size as in Piiymys ihericus centralis^ but 

 colour much darker (upperparts a uniform bister, nearly as 

 dark as that of Ridgway, faintly varied by blackish hair-tips 

 and tinged with wood-brown on sides ; underparts dull slaty 

 grey washed with buffy ; feet whitish, in rather marked 

 contrast with body ; tail very obscurely bicolor, whitish tinged 

 above with brown). 



Measurements. — Type. Head and body 104 mm. ; tail 22 ; 

 hind foot 17 ; ear from meatus 10. Skull : condylo- basal 

 length 24"2 ; zygomatic breadth 14"8; interorbital con- 

 striction 4'2 ; occipital breadth 11'4 ; occipital depth 6 4 ; 

 palatal depth 7'6 ; nasal 6*0 ; diastema 80 ; mandible 16'4 ; 

 maxillary tooth-row 5'8 ; mandibular tooth-row 5"8, 



Specimens examined. — Two, both from the type locality. 



Remarks. — The two specimens exactly resemble each other 

 and differ conspicuously from all the other Spanish skins 

 examined. Apparently this form is confined to the Dehesa, 

 as in a male taken by Mr. Gonzalez at Catarroja on the 

 adjacent mainland the colour is indistinguishable from that 

 of P. ihericus centralis.
