angular in shape. Above, the fold is attached to what 

 may be regarded as the left post, process of the spleen. 

 Its left margin is free, and below it is attached to the 

 caudal pole of the left kidney. Occasionally the left por- 

 tion of the pancreas may be more compact and more fixed 

 dorsally. The greatest length of the pancreas from side 

 to side is 11 cm.

Wombats (A, and D,), 



Specimen (A). — The portions L.M., though repre- 

 senting the left mesial or cystic of the tripartite cystic 

 lobe, are now part of the left (lateral) lobe, as is definitely 

 shown on the diaphragmatic aspect. The anterior por- 

 tion is still separated at ventral margin by a fissure, but 

 on the visceral surface there is only a groove between the 

 two, which is not seen diaphragmatically. The longitudi- 

 nal fissure is between the portions I.M. and L.M. 



I.M. represents the intermediate cystic or mesial of 

 the tripartite, but is now L.M. The longitudinal fissure 

 corresponds to the cystic or mesial fissure of the tripar- 

 tite cystic lobe and on diaphragmatic surface, as is shown 

 in diagram, it is related to the suspensory ligament. 



Specimen (ZJ).--The portion L.M. is now part of the 

 left (lat.) lobe, and should be labelled L. The groove be- 

 tween these two portions, L.M., and the large portion, L., 

 represents the old left lateral fissure. I.M represents the 

 intermediate lobe of the tripartite cystic lobe, and is now 

 I j.M. Its left boundary — the longitudinal fissure — repre- 

 sents the old mesial or cystic fissure, and is connected on 

 diaphragmatic surface with the suspensory ligament.
