The left lobe is rather small, next to the fissure it is about 12 cm. 

 and the greatest distance from the fissure to the left margin is about 

 HI cm., but hardly half of that at the dorsal border. The right lobe 

 measures from the fissure to the right free border about I6V2 cm. 

 There is a small fissure indicating the limit of a right central lobe 

 which measures 13 cm. from the dorsal to the ventral free border. 

 The pathologically enlarged gallbladder is connected with the right 

 lateral lobe which is prolonged at this junction so that its longest ex- 

 tension from the dorsal border to the free margin is about 16 1 2 cm. 

 The caudate lobe is trihedral, but short (5 72 cm.), and caps together 

 with the posterior dorsal portion of the right lobe the kidney in a 

 similar way as in the Gnu 1 ). The Spigelian lobe is only slightly de- 

 veloped with a broad base and rounded tip. 



The spleen is elongate but at the same time broad and with 

 both ends equally rounded. Its length is about 25 cm. and its width 

 about 9 cm. at the thicker fixed end, and 8 cm. at the other. It 

 thus, to a certain degree, resembles the same organ of the Gnu and 

 at the same time its shape is intermediate between the very elongate 

 one of Bos taurns and the primitive elliptic one as exhibited by Ovibos, 

 Cervicornia, Giraffa etc. being, however, somewhat more taurine than 

 that of the Gnu. 



Both kidneys of the Anoa are beanshaped and of almost the 

 same size not quite attaining a length of 9 cm. and with a breadth 

 of 4V2 cm. or a little less (the left). Their greatest thickness is about 

 3 '/2 cm. Exteriorly they show a surface which is not quite even, but 

 provided with impressions and furrows, which although less strongly 

 developed than in the. kidneys of Bos, remind one about the condition 

 of those and give a hint that the kidneys of the Anoa are not so 

 simple as those of the antelopes, sheep etc. A longitudinal section 

 reveals also the remarkable fact that the Anoa-kk\ney interiorly is just 

 as complicated as that organ of the common ox, that is; every cone 

 is distinct and opens each with a separate mamilla in a tubular pro- 

 longation of the renal pelvis. Heller (1. c. p. 29) who has shortly 

 described some of the viscera of a quite young calf of Anoa says that 

 the kidney of that was 4.:. cm. long and without lobulation. He has, 

 however, as far as can be seen from his words, not made any section 

 of the kidney, but only inspected its exterior surface. It is, however,
