302 LÖNNBERG, ON DASYPUS MINUTUS. 



a short gastrosplenic omentum. The pancreas is very long, but 

 thin. Its left restiform portion extends from the spleen along 

 the margin of a Prolongation of the Omentum gastrolienale in a 

 curve across the abdominal cavity to the mesenterium duodenale 

 in which it is greatly expanded. It opens into the duodenum, 

 not quite 2 l J2 cm. from the pylorus. 



The liver has 6 greater lobes, three on each side. The 

 right posterior lobe extends far back, and, as in Tolypeutes 

 (Murie), it receives and partly covers the right kidney. It is 

 held in this position by a very strong ligament on the median 

 side. The two upper right lobes, of which the central is larger, 

 are, if counted together, larger than the three left lobes. Of 

 these the two median ones overlap each other and the lateral 

 has on its median surface a deep fissure to receive the lateral 

 margins of the two central left lobes. In the median line, just 

 above the upper end of the posterior right lobe, there are two 

 small lobules. The lower of these is tongue-like and connected 

 with the above mentioned right posterior lobe. The upper is 

 nearly quite free and corresponds to the Spigelian lobe. The 

 gallbladder is situated on the posterior side of the central right 

 lobe, in which it is imbedded. The biliary duct unites with the 

 pancreatic. The situation of the gallbladder is thus similar to 

 the same in Tolypeutes tricinctus (Murie 1. c), but not to that 

 of Dasypus 6 cinctus according to Owen's description. 1 ) In 

 the latter this author found the gallbladder to be so deeply im- 

 bedded in the liver that it »appeared on the convex side of that 

 viscus». Dasypus minutus resembles Tolypeutes tricinctus in 

 another and more important character with regard to the liver, 

 namely, in having a great portion of this organ drawn out 

 posteriorly and surrounding the anterior part of the right kid- 

 ney. This characteristic is by Murie regarded as »a condition 

 or variation, possibly an adjustinent, reconcilable with its re- 

 markable power of body flexion». Dasypus minutus is thus in
