Anoa stands, no doubt, in connection with the shortness of the neck 

 of this animal. Sonic of the rings had even become confluent with 

 each other, which may indicate thai n secondary reduction in number 

 has taken place. 



The left lung has three lobes, the right four and an azygous 

 lobe. The division is thus similar to that of the common ox. The 

 Anoa-hmgs are also distinctly lobulated as in cattle. 



When the Anoa-v entncle was moderately expanded the following 

 dimensions were recorded: total length of dorsi-sinistral sack counted 

 from the cardia 4)5 cm., distance from the cardia to the posterior end 

 of the ventri-dextral sack 4b cm. 1 ). The diameters of the reticulum 

 were resp. 15, 10, 10 and those of the psalterium 9, 5, 7. The dorsi- 

 sinistral sack does not project so far backwards as the other but its 

 saccus cœcus is more pointed while that of the ventri-dextral sack is 

 more broadly rounded. The latter saccus cirrus is also larger, mea- 

 suring 12 cm. as well in length as in breadth and is well defined all 

 round by a sulcus coronarius. The saccus cœcus of the left sack is only 

 10 cm. in length and 8 cm. across at its middle. Its sulcus coronarius 

 is not so sharply defined. \Yith regard to the backward extension of 

 the sacci cceci (he Anoa thus differs from Bos taurus, but although the 

 left saccus raras is a good deal smaller than the right it seems to be 

 better developed than the same in sheep and in antelopes (as far as 

 the latter are known). 



The small size of the psalterium when compared with that of 

 the reticulum is as Heller 2 ) already has noted a difference from the 

 prevailing condition in Bos taurus. In this respect the Anoa resembles 

 the less specialised Ruminants as antelopes, goats, deer. 



According to Heller (1. c.) the psalterium of the Anoa is tri- 

 plicate. 



The abomasus is about 22 cm. long and !) cm. broad. 



The small intestine of this specimen measured only about 890 

 cm. while adherent to the mesentery and in an empty state. This 

 is remarkably short which may be deduced from the fact that I have 



l ) When Heller (in: »Der Urbüffel von Gelebes») from a blown up ventricle lias 

 recorded that the left sack is longer than the right this is quite correct when one does not 

 count from the cardia but only from the anterior end of the right sack. If so is done on 

 this specimen the length of the ventridextral sack is found to be about 37 cm.
