flat. Towards the blind and rounded end it is somewhat narrowed, 

 IS mm. across. The blind end protrudes very little beyond the free 

 margin of the liver, unlike the case in the Gnu and the ox. Ductus 

 choledochus is wide. Its opening in the duodénum has already been 

 described above. The shape of the gall-bladder is quite different to 

 ilmi of the Saiga to judge from Mtjbie's description of the same in 

 which it is termed »short roundish» and the fossa »small and shallow». 

 Only an undulation of the margin of the right lobe indicates its divi- 

 sion in a central and a lateral portion. There is a comparatively large 

 Inh/is Spitjelii with broad base about 4- cm., and rounded free margin 

 protruding about 1 cm. Lobas caudatus must be termed comparatively 

 large measuring almost 5 1 / 2 cm., trihedral in shape and with a large 

 impressio renalis on its right side. The great breadth of the base of 

 the Spigelian lobe agrees with the »oviform» type according to Gareod's 

 terminology (I. c.) but as I have remarked before not much stress 

 can be laid on the shape of such a variable organ. The caudate 

 lobe also resembles in some degree the same of the sheep. In the 

 Saifjfi the Spigelian lobe is, according to Murie (1. c), »but scantily 

 developed* and the caudate lobe is »bayonet figured». It is, however, 

 as it seems from Murie's description, larger than in the Black-buck 

 and extending beyond the right border. On the whole, there exists a 

 certain resemblance in the shape of the liver in these animals. 



The pancreas does not present any remarkable feature. Its 

 duct seems to juin the ductus choledochus and I have not been able to 

 detect any independent duct to the intestine. 



The spleen of the Black-buck is triangular in outline, but much 

 more elongate 1 ) than in sheep and goats. It measures in fresh state 

 12.") mm. in length by 55 in breadth at the broadest place and 10 in 

 thickness. The longest side of the triangle is convex and somewhat 

 undulated, the others straight. The triangular shape of the spleen 

 may be regarded as an ovine characteristic, as it differs so much 

 from the oval shape of this organ in the Cervicomia, Giraffa and Ovi- 



1 ) I take this opportunity of correcting a misprint which has through inadvertence 

 taken place in my paper »on the soft anatomy of the Muskox» (Proc. Zool. Soc. London 

 HtOO). In setting the types a few words have been omitted on page löli. In the middle 

 of this page it should be read: »The spleen of the Muskox is not elongate as in Bos or 

 triangidar as in Ovis and Capra — — — — », but the words in italics have unfortunately 

 been dropped.
