paunch. In the adult the length of the psalterium is hardly a fourth 

 of the length of the paunch. This proves that the psalterium of Ce- 

 phalophus ogilbyi has become secondarily reduced in correspondence 

 with its carpophagous diet as stated above. Eight large primary folds 

 are developed here, and in addition to them a few (two on one, one 

 on the other) rudiments of, as it seems, secondary folds in the lateral 

 interspaces. To judge from the large interspaces between these rudi- 

 mentary folds and the adjoining large folds, which fully equal the 

 interspaces between two large folds at other places, I am inclined to 

 think that also the small folds belong to the primary system, but have 

 become suppressed for the purpose of leaving better room for the ad- 

 joining folds as they are situated at the lateral curving of the wall. 

 The height of the middle folds is about 4 mm. and they leave a com- 

 paratively smaller free lumen than in the adult. The abomasus is, as 

 is normal in a foetus, large, its length measured along the curvature 

 being about twice the length of the paunch. The wide fundus-portion 

 of the abomasus shows on its inner surface ten broad or high (3 — 4 

 mm.) folds (the same number as in the adult). Between these large 

 folds a number of lower transverse folds run crosswise from one large 

 longitudinal fold to another. In the narrowed pyloric portion the folds 

 disappear or are only continued as quite low ridges towards the py- 

 lorus. The inner structure of the abomasus is thus similar to the 

 same in the adult. 



The general arrangement of the intestine is already the same 

 as in the adult. The blind end of the caecum is narrowed and the 

 large intestine forms three centripetal and two and a half centrifugal 

 coils before it runs out in the peripheric mesentery. When the large 

 intestine has left the connection with the small intestine it does not 

 run as a straight rectum to the anus, but makes from the region of 

 the left kidney a transversal coil dorsally and to the right side and 

 then back ventrally and to the median line where it proceeds in the 

 pelvic region to the anus. 



The situation of the liver has already been mentioned. The 

 right lobe which is much the largest extends longitudinally along the 

 body wall. Except the umbilical fissure there is no other fissure di- 

 viding the two main lobes. The caudate lobe is very large, thickly 

 trihedral and even extending beyond the margin of the right lobe. 

 Together with the margin of the latter the caudate lobe not only caps,.
