Notes on the morphological anatomy of the Anoa. 



The viscera of a young bull of Anoa have given me the oppor- 

 tunity of making the following notes. 



The tongue must be regarded as rather short, only measuring 

 15 cm. in length. Its breadth is almost the same posteriorly, and in 

 front about 3 V2 cm. 



As in Antilope and some other antelopes the anterior portion, 

 not quite half the tongue, is pigmented 1 ). The papillœ filiformes are 

 flattened, scale-like with blunt tips, thus differing from those of Bos 

 which are more narrow and pointed. On the posterior thick portion 

 of the tongue the enlarged papillœ filiformes are in the centre more 

 or less bluntly conical, partly curved. Towards the sides they become 

 more flattened and truncate, but also here recurved. Their general 

 shape differs here as well from those of Bos as those of Ovis and 

 v Antilope. The papillœ fungi •formes are rather evenly scattered all over 

 the upper surface of the anterior portion of the tongue, being, how- 

 ever, as usual more closely set at the margin. Near the transverse 

 groove dividing the anterior thin and posterior thick portion these pa- 

 pillae are scarce in the middle, but appear again further posteriorly. 

 On the whole it can be said that these papillse are comparatively nu- 

 merous and more evenly distributed than in other Gavicornia (except 

 Bos and Ovibos) instead of leaving a central space free as is usually 

 the case. Heller (1. c.) says, however, that the papille fungiformes 

 are comparatively better conspicuous in the young Anoa than in the 

 old. The papillœ circiimvallatœ are arranged in two rows' 2 ) the outer 

 consisting of nine or ten and the interior of five papillae. In this re- 

 spect the Anoa agrees pretty well with Bos and its number of such 

 papillae exceeds that found in Antilope, Connochœtes etc. 



The thymus-glmid had been cut to pieces on the preparate so 

 that only the anterior ends were left. These were situated on either 

 side of the larynx and resembled in appearance the same organ of 

 the common calf. 



The thyrcoidea has the shape of a flattened reddish body situated 

 at the sides of the trachea, just behind the larynx and near the dorsal 



*) This may be variable to judge from the statements by Heller in »Der Urbiiffel 

 von Gelébes». 



2 ) Helleb talks about a third »row» consisting of 1 papilla, this is not found in 

 this specimen.
