duodenum, in the centre of which process there was a slight de- 

 ficiency. 



"The spleen was shorter and thicker than in Das. Pe/^r/, measuring 

 2^ inches in length, and 2 in breadth. There was no supernumerary 

 spleen as in the young male. 



" The suprarenal glands were as large as almonds : they were very 

 elastic ; and on pressure, the blood which they contained was pro- 

 pelled along the vein. In section they presented first a distinct fibrous 

 cortical part, then a dark coloured portion, and lastly a firmer sub- 

 stance in the centre." 



Mr. Owen subsequently adverted to several external peculiarities 

 which he had observed in the 6-banded Armadillo, and which, he re- 

 marked, were of some interest, as connected with the burrowing habits 

 of the animal. On the second toe from the inside there is a soft 

 large cushion, evidently a modification of the organ of touch : at the 

 hinder part of the fore-foot there is also a warty prominence, from 

 which many hairs grow. There is a loose portion of integument below 

 each eye, supported upon a prominence of the zygoma, hirsute, 

 and resembling an inferior eyebrow ; by means of which, and the 

 coronal plate of armour above, the eye is well defended during the 

 act of burrowing.
