petal coil and including the peripheric coil 2 eentrifugal ones. 

 The whole length of the large intestine is only 236 cm. The in- 

 testine of this species is thus not only absolutely shorter than 

 that of C. ogilbyi but the small intestine is not far from one 

 fourth shorter than it ought to have been if it should have had 

 the same relative size as that of C. ogilbyi. The colic spiral is 

 also less complex in the Red Duiker than in its relative from 

 Cameroon, it is thus probable that the former subsists on an 

 even less coarse diet than its partly carpophagous relative 

 (conf. (6) p. 20 & 21). The relation between the length of 

 the small and that of the large intestine is almost the same 

 in Cephalophus natalensis as in C. tnelanorheus (6). Witli 

 regard to the number and arrangement of the colic coils C. 

 natalensis occupies an ^ntermediate position between C. mela- 

 norheus and C. ogilbyi. 



In a foetus of Tragelaphus the colon forms 3 centripetal 

 and 2V2 eentrifugal coils, and then it runs out in the com- 

 mon mesentery and forms a long peripheric coil in close con- 

 nection with the small intestine. The large intestine of this 

 animal must thus have a considerable length which is in 

 agreement with Garrod's figures (1). According to this 

 author the large intestine of Tragelaphus scriptus should be 

 more than half as long as the small one. The shape of the 

 Spigelian lobe of the liver is not of so great morphological 

 importance as Garrod (1) believed it to be. So has, for 

 instance, the author quoted stated (1. c. p. 4) that this lobe 

 is rudimentary in »Strepsiceros kudu», but in a young bull of 

 this kind I have measured the same lobe and found it to 

 have a lenght of about 4 cm. and a breadth of 2V2 cm., thus 

 far from rudimentary. Its general shape was somewhat 

 tongue-like and its base was narrowed so that it might be 

 termed pedunculate, or »rusiform» according to Garrod's 

 terminology. The caudate lobe was rather small, about 7 cm. 

 in length. In a similar way the umbilical fissure in this 

 specimen extends through one third of the organ, but in 

 Garrod's specimen only through one sixth. 



The spleen of the Koodoo is rather elongate measuring 

 about 23 V2 cm. in length and about 10 in breadth.
