this surface coiiformed to what is fouiid in man. Thus, the lob. q u a d r a t u s was situated between the hilum and the 

 deep fissures which were occupied by the lig. teres and the gall-bhulder respectively. The S p i g e 1 i a n lobe was placed 

 between the hilum and the grooves occupied by the inferior vena eava and the ductus venosus respectively. In this way 

 three lobes — induding the pendulous one, which was in reality alob. caudatus — were left to represent the remainder 

 of the right lobe of human anatoniy, while the left lobe of the human liver was represented by the two lobes already refer- 

 red to as lying to the left side of the falciform ligament. The lig. teres (obliterated umbilical vein) was crossed by a 

 pons hepatis. This ligament was patent to a distance of 4 inches from the liver. Further, the unobUterated lumen com- 

 municated with the portal vein at the left end of the hilum, while the ductus venosus, which was continued to join 

 Vena cava inferior, was patent throughout its entire length, and quite readily admittcd a dissecting-room blow-j)ipe. 



The g a 1 1 - b 1 a d d e r was empty, and, as already mentioned, it occupied a deep fissure on the abdominal aspect 

 of Ihc liver, while its fundus projected towards the diaphragmatic surface, and extended some distance beyond the ventral 

 border of the liver. The termination of the bileduct has already been referred to. 



The spieen was a flattened organ, attached to the left aspect of the greater curve of the stomach by the gastro- 

 spleiiic Omentum. It was also suspended to the lumbar region by the phrenico-splenic ligament. Its maxinuim length was 

 14 inches and its maxinuim breadth 5 inches. The anterior or ventral border presented numerous notches, and on its outer 

 surface there were half a dozen sHt-hke depressions, none of which were more than an inch and a half in length. On its 

 gastric surface there were two longitudinal and parallel lines of entrance for bloodvessels. The interval between these lines 

 was covered by Peritoneum belonging to the lesser jjeritoneal sac. This area was slightly lobulated, and presented two or 

 three projecting portions of spieen substance. 



The p a n c r e a s was not at any point in contact with the spieen. The association of small intestine with the hcad 

 of the pancreas and the termination of the pancreatic duct have already been mentioned." 



Nach Ellen BERC4ER besitzt Phoca einen einfachen, schlauchförmigen Magen ohne Cardia- 

 drüsenregion. 



Nach Lee he (1899) ist bei Pinnipedia im allgemeinen 



„der Magen stark verlängert, schlauchähnlich; der Pylorustheil ist gegen den C'ardiatheil umgebogen. Oft liudet man 

 im Magen verschiedener Pinnipedia größere und kleinere Steine, welche w a h r s c h e i n 1 i c h dazu dienen, die ungekaut 

 verschluckte Nahrung durch die Bewegung der Magenwand zermalmen /u helfen. Eine Cardiadriisenregion fehlt." 



,,Die Pinnipedia zeichnen sich durch die bedeutende Länge und das kleine Lumen des Darmkanals aus; das Coecuni 

 ist einfach und klein." 



„Die Leber der Pinnipedia ist wie bei Fissipedia gebaut, doch sind die Lappen durch eine größere oder geringere 

 Anzahl Furchen ausgezeichnet; diese Zerklüftung ist bei Otaria am stärksten ausgesprochen." 



Bei einem jungen weiblichen Walroß beschreibt Burne (1909) den Ductus hepato -pancrea- 

 ticus mit folgenden Worten: 



,,The bile duct enters the intestine at a very acute angle close to the beginning of the duodenum. After running for 

 3 cm. without change within the substance of the wall, it opens suddenly by a well-defined circular aperture through the 

 side wall of the elongated Chamber described by Murie as the terminal part of the duct. This is not quite the same thing 

 as ,,enlarging into a capacious duct". The pancreatic duct enters the intestinal wall upon its concave aspect 1 cm. below 

 the bile duct; it passes, within the substance of the wall, diagonally dowiiwards towards the convex border of the gut super- 

 ficial to the bile duct and opens into the elongated Chamber upon a prominent papilla, just to the colic side of the opening 

 of the bile duct." 



,,The relative size of the elongated Chamber and its coarse structureand appearance agreein avery rcspect with Murie's 

 description. It may be mentioned, however, that the papilla on which it opens is circumvallate, being surrounded by a 

 sharp circular fold of nuicous menibrane." 



„Sections through the bile duct, elongated Chamber, and intestine sliow that in miiuite structure the elongated Chamber 

 resembles the intestine rather than the bile duct; and there is little doubt, both on this grouud and from the mode of entry 

 into it of both the bile and pancreatic ducts, that this Chamber is really a diverticulum of the intestiiui and not a dilated 

 part of the bile duct." 



,,The Sea-Lion, from Murie's description and figure, has a similar intra-inural bile reccptacle; but I do not kiiow of 

 its occurence elsewhere except in the Chelonia, especiaUy Dermochelis and, as I am told by Mr. Beddard, in the 

 Edeiitate Mijrmecophaga. 



Der, so viel ich weiß, einzige Autor, der die Anatomie der uns hier interessierenden Organe 



bei Leptonychotes WeddelH eingehend beschrieben hat, ist Hepburn (1909).
