PR. J. MURIE ON THE THREE-BANDED ARMADILLO. 87 



deep fissure, extending from the front surface of the liver obliquely inwards and back- 

 wards to near the middle of its posterior surface, into two lobes, an inner and an outer 

 (4 and 5, fig. 11), of which the inner is by far the smaller. The right moiety is divided 

 by two externally deep fissures, which extend from the convex anterior and outer surface 

 of the liver nearly to its posterior face, into three lobes — an anterior, a middle, and a 

 posterior (3, 2, 1, fig. 11). The anterior of these is the smallest ; and its convex anterior 

 face is marked by a deep groove, which extends towards the middle line, and ends 

 towards the falciform ligament. The under surface of this lobe carries the gall-bladder, 

 which is elongated, straight, and fusiform, and half sunk in a deep fossa. On the left 

 this lobe is bounded by the median fissure, posteriorly by the transverse fissure, into 

 which the vessels enter as usual. The space or region of the under surface of this lobe, 

 between the gall-bladder and median fissure, answers to the lobus quadratus. The part 



which might be regarded as the lohiis Spigelii is prolonged backwards, and passes into the 

 other two divisions of the right moiety of the liver. The posterior surface of the second 

 of these (1, fig. 11) is concave, and exactly receives the convexity of the kidney. After 

 having been thoroughly soaked in spirits, and therefore much contracted, I noted that 

 the left lobe (No. 5) measured 2 inches by \\ across. No. 4 was less, and No. 3 above an 

 inch in diameter. Nos. 2 and 1 were each about a couple of inches long and from 



1 to IJ inch at widest. 



The right coronary ligament is connected with the posterior superior nngle of this 

 division, and passes thence to the spine, and is continued upwards by the side of the 



spine to the diaphragm. 



The free edge of the falciform ligament extends from the notch which divides the right 

 and left halves of the organ to the under surface of the xiphoid process. The ligament 

 itself passes back along the under surface of the diaphragm on the one hand an d the 

 front surface of the liver on the other, to the place of reficction of the coronary 



Hgaments. 



The left coronary ligament takes its origin opposite to the last rib, and is continued 

 thence, presenting a free margin backwards to the left lobe of the liver, to which it is 

 attached, about three tenths of an inch from its free margin. 



In species examined by myself— among others the Weasel-headed Armadillo, D. 6- 

 cmctus {=D. encoubert)\ the Peludo or the Hairy Armadillo, JEuphradus villo6U8, the 

 Pichy or Little Armadillo, UupJir actus {= Dcisy pus) minutiis, and Cachiamc, D. {Taiusia) 

 peha—ihQ liver is essentially identical with that of Tolypeutes in the number and 

 general disposition of the lobes &c. Eut there is this difference, that the latter peculiar 

 genus has a larger mass on the right side drawn out posteriorly and covered by- gut— a 

 condition or variation, possibly an adjustment, reconcilable with its remarkable po\v ir 

 of body.flexion. The Pichiciago {CJilamy dophorus) has a liver, in divisions and general 

 figure, most nearly agreeing with the commoner Armadillos than with the IVFataco. 



Kidneys.— T^hQ situation of these has been incidentally mentioned in th.i relative 

 position of the viscera. The left one had such a remarkably rotund nppearancc, and so
