this respect more adapted for rolling itself into a ball than the 

 other species of Dasypus. It must, however, be observed that 

 MüRlE, who declares himself as having examined several species 

 of Armadillo among them »the Pichy or little Armadillo Euphrac- 

 tus (= Dasypus) minutus», states that only Tolypeutes has the 

 liver shaped after the mentioned fashion (I. c. p. 87). But he 

 might possibly be ni istaken, as it does not seem probable that 

 such a character should vary within the same species. 



Contrary to what is the case in Tolypeutes (Murie) the 

 right kidney is 1 arger, (measuring 21 mm. in length by 15 in 

 breadth) than the left, the measurements of which are 17 and 

 11 mm. resp. The situation of the kidneys is also different from 

 the same in Tolypeutes, the right and larger kidney being an- 

 terior to the left and smaller. The latter lies entirely in the 

 pelvic region and does not extend to the anterior margin of os 

 ilei, but the former has about half its body anterior to os ilei. 

 The suprarenal body on the left side is 7 mm. in diameter and 

 larger than the right. The former has a rounded but flat shape 

 and is free from the kidney, but attached to the spine. The 

 right one lies between the right caudal lobe of the liver and the 

 kidney, and is thus pressed against the latter organ. 



The genital organs resemble those of the male Dasypus 

 villosus described by FaüVEL (1. c.) and still more those of Da- 

 sypus sexcinctus according to Alessandrini (1. c. Tav. 13, fig. 8) 

 because the shape of the urinary bladder is short and rounded, 

 not extended into an anterior tip as on Fauvel's figure. The 

 construction of the generative parts seems, on the whole, to be 

 so alike in the armadillos that this species, with regard to them, 

 does not show any marked resemblance to Tolypeutes as it does 

 in other respects, as is seen above. 



The brain is not in a good condition, it can however be 

 seen that its general appearance is very much like that of the 

 brain of Dasypus sexcinctus, as it is figured by Turner (Journ. 

 of anat. a. physiol. I, p. 314). The oblique sulcus on the 

 superoparietal cerebral surface is more developed so that it
