ntimbcr just about 100: first nuchal row consisting ot" 11 

 scales and extending quite trom ear to ear ; seconrl row, as 

 usual, forming a complete collar extending from shoulder to 

 shoulder and consisting of 28 scales. Fixed shoulder-shield

 movable. Central scale of the seventh row from the end 

 ])erforated. Fifth body-row consisting of 39 scales. 



Carajiaee thinly clothed with long scattered hairs, from 1 

 to 3 inches in length, of a pure white colour. Underneath 

 and between these there are shorter and more numerous brown 

 hairs, which, on the medial line of the back and on the pelvic 

 shield, are in the majority, while on tlie flanks the longer 

 white hairs are most numerous. Limbs and belly thinly 

 clothed with Avhitish or pale brownish hairs. 



Ears naked, black, somewhat elongate, their length about 

 equal to half that of the cephalic shield. Tail imperfect, its 

 proximal portion very thinly haired, almost naked. 



Skull only represented by the muzzle, but this, like the 

 ceplialic shield, is of unusual jDroportionate breadth ; nasals 

 large, boldly expanded in their posterior half. Anterior 

 tooth, as in typical Dasypus^ implanted in the premaxilla, 

 just anterior to the suture. 



Dimensions of the type (an adult skin) : — 



Head and body, length in a straight line 268 millim., over 

 the curves 350 ; cephalic shield, length 60, breadth in a 

 straight line 61, over the curve 71 ; transverse length of first 

 nuchal band (straight) 47 ; ear-length (approximate) 30 ; 

 length of middle body-band, following the curve, 230 ; hind 

 foot, length without claws (approximate) 52. 



Skull : nasals, length 26'3, breadth anteriorly 7, at nar- 

 rowest point 6*1, at broadest point 12"6 ; breadth of anterior 

 nasal opening 8'4 ; anterior tooth, distance from nasal 

 opening 9; breadth of palate between anterior maxillary

Hah. Orujo, Bolivia. 



This new species differs from D. veUerosus in its con- 

 siderably larger size, much broader cephalic shield, longer 

 ears, less amount of hairiness, and, in the skull, in the much 

 broader muzzle and nasal opening and in the larger and 

 (posteriorly) more widely expanded nasals. All these 

 characters, and its equally inferior size, will also readily 

 separate it from the common hairy armadillo, D, villosus.
