164 Miller — Descriptions of Two New Mole Hats. 



Cranial measurements of type: Greatest length, — (49*): basal length. 

 — (44.4): basilar length. — (40.4); occi pi to-nasal length (from inion). 

 30.4 (39); palatal length, 22 (29.4): diastema, 12 (17); length of nasals, 15 

 (20); breadth of both nasals together anteriorly, 5.2 (6.8); breadth of 

 both nasals together posteriorly, 1.8 (2.8); greatest breadth of rostrum. 

 7.4 (10): zygomatic breadth, 27.2(35); mastoid breadth, 22 (26); least 

 interorbital breadth, 7 (6.4): palatal breadth between middle molars, l.S 

 (2.4): depth at middle of palate, 18.4(18.8); least depth of rostrum be- 

 hind incisors, 5(7); mandible from condyle, 24.8(81); mandible from 

 root of incisor. 24.6(30); depth of mandible through coronoid process. 

 12.8 (17.6); upper molars, alveoli, 7.8 (8); upper molars, crowns, 8 (7): 

 width of second upper molar (crown), 2.2 (2.8); lower molars, alveoli. 7.6 

 (7); lower molars, crowns, 6.4 (7); width of upper incisor at alveolus, l.S 

 (2.6); width of lower incisor at alveolus, 1.8 (2.6). 



Specimens examined. — Four, all from the vicinity of Beyrout. 



Remarks. — In dental characters this species appears to be much like 

 Spalax kirgisorum, an animal from which it differs very conspicuously in 

 the large size and robust form of the skull. From its near geographic 

 allies, Spalax ehrenbergi and Spalax intermedins it is also readily distin- 

 guishable; from the former by the absence of a reentrant fold on the 

 inner side of the third upper molar and by the presence of only one fold 

 on inner side of middle lower tooth; from the latter by the longer parie- 

 tals (7 mm. instead of 5 mm. along sagittal crest), and by the absence of 

 distinct grooves on the face of the incisor teeth. 



* Measurements in parenthesis are those of an adult male (much older 

 than the type) from the same locality (No. ff£$f).
