the nine-banded Armadillo, the anatomy of which has been recently 

 given (p. 141.). Its head is shorter and broader, and the coronal 

 plate of a triangular, instead of an oval, form. The middle bands also 

 become more gradually blended with the last portion of the armour, 

 and the tail is much shorter, measuring only 4| inches in the present 

 species, while in the nine-banded it is nearly 9 inches in length. The 

 ears, though of the same form, are also proportionally shorter, being 

 but 1 inch in length and half an inch in breadth. The most important 

 differences, however, are in the additional toe on the fore-foot of the 

 Weasel-headed species, and the additional teeth implanted in the in- 

 termaxillary bones. Of these this young animal had already acquired 

 its full complement, having 9 — 9 in the upper jaw, and 10 — 10 in the 

 lower, all of one character, simple, cylindrical, and separated by in- 

 terspaces. There are also remarkable differences in the forms and 

 proportions of the scales in different parts of the armour of the two 

 species. 



"On laying open the abdomen the viscera presented much the same 

 appearance as in the nine-banded species, except that the gall-bladder, 

 being more deeply imbedded in the liver, appeared on the convex side 

 of that viscus. 



"The stomach had the same general form j but a greater proportion 

 of the cavity was situated to the left of the oesophagus, the whole of 

 the dilated globular part or reservoir being so placed. The length of 

 the stomach when distended was 3| inches, its greatest perpendicular 

 diameter or depth 2^ inches : the oesophagus entered 2 inches from 

 the left extremity. The lining membrane was uniformly villous ; ruga 

 were seen abo\it the middle of the cavity -, these were few in number, 

 longitudinally disposed, and converging towards the pyloric end. The 

 parietes of the stomach, which are thin at the greater end, become 

 increased (as in the species formerly described) by the accession of 

 muscular fibres, and at the pylorus attain a thickness of 2 lines. This 

 part is unprovided with the valvular protuberance observed in the 

 stomach of the nine-banded species, but the pyloric orifice was so small 

 that it was with some difficulty that 1 could discover it : from its 

 oblique situation and the thickness of the surrounding parietes, I have 

 no doubt that the same purpose is attained of opposing the egress of 

 the alimentary matter during the time it is undergoing the requisite 

 comminution. The stomach externally has the same tendinous appear- 

 ance on each side at the smaller end. 



91 The duodenum receives the biliary and pancreatic secretions at 

 the distance of I inch from the pylorus; its dispositions and connec- 

 tions, together with those of the rest of the small intestines, were the 

 same as in the nine-banded species; but their length was in this speci- 

 men much less, being only 9 feet 6 inches. With respect to the large 

 intestines a remarkable difference presented itself in the presence of 

 two short but wide cceca, between which the small intestine entered 

 the colon, and terminated. The largest of these pouches was very thin 

 in its coats, and its length was an inch j the parietes of the smaller 

 pouch were thicker, and exhibited patches of glands on the inside ; its 

 length was half an inch. The terminal orifice of the 'Hum is in the
