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 vvith the lašt poition of the armour, 

 and the tail is much shorter, ineasuring only 4^ inches in the present 

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

 ears, though of the šame form, are also proportionaliy shorter, being 

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

 difl'erences, houever, are in the additional toe on the fore-foot ot the 

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

 termaxillary bones. Of these this j'oung animal had already acquired 

 its fiiU complemenl, 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 diflerent parts of the armour of the two 

 species. 



" On laying open the ahdomen the viscera presented much the šame 

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

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

 of that viscus. 



"The stomach bad the šame general form ; but a greater proportion 

 of the cavity was situated to the left of the cesophagus, 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 cesophagus entered 2 inches from 

 the left extremitv. The lining membrane vvas uniformly villous ; rugce 

 were seen ab(fut the middle of the cavity; these were fevv in number, 

 longitudinally disposed, and converging towards the pyloric end. The 

 parietės 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 pyloms attain a Ihickness of 2 lines. This 

 part is unpiovided with the valvular protuberance observed in the 

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

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

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

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

 the alimentarv matter during the time it is undergoing the reąuisite 

 comminution. The stomach externally has the šame tendinous appear- 

 ance on each side at the smaller end. 



" The duodenum receives the biliary and pancreatic secretions at 

 the distance of 1 inch from the pyloms; its dispositions and connec- 

 tions, together vvith those of the ręst of the small intestines, were the 

 šame as in the nine-banded species; but iheir length vvas 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 vvide ccsca, betvveen vvhich the small intestine entered 

 the colon, and terminated. The largestof these pouches vvas very thin 

 in its coats, and its length vvas an inch ; the parietės of the smaller 

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

 length vvas half an inch. The terminai orifice of the lium is in the
