difference, but within Mr. Simons's set there are some varia- 

 tions worthy of note. Thus in some specimens tliere are 

 only two rows of small scales on the middle line of the 

 shoulder-shield, and in others there are three, others again 

 having an irregular intermediate condition. Then in the 

 skull the variation in the shape of the nasals is very con- 

 siderable, thcso being in some long and narrow (breadth 

 about y millim.) and in others far broader (12"8 millim.). 



Dimensions of the tyj)e : — 



Head and body 237 millim. ; tail 103 ; hind foot, s. u. 44:, 

 c. u. 48 ; ear 31. 



Skull : greatest length in middle line 64*5 ; basal length 

 52 ; zygomatic breadth 41 ; nasals 22 x 12'8 ; constriction

The type of D. vellerosus is rather smaller (skull length 

 61), but the Tucuman specimens are of the same size as 

 I). V. pannosus.
