cm. and those of the right are resp. 16 and 10 cm. The latter is however a little 

 thicker. The fissure between these lobes does not extend half way through the organ 

 (conf. Pl. III fig. 2). A slight undulation of the margin of the right lobe indicates a middle 

 lobe. There can hardly be discerned any distinct spigelian lobe although a slight in- 

 dication may be traced. Lohus caudatus is of medium size about 8 cm. in length. It 

 is almost triangulär and shows an impressio renalis at its right side. The gallbladder 

 has the same situation as in Bos and extends with more than half its length beyond the 

 margin of the liver. It is very large, measuring about 14 cm. in length. Its shape may 

 be seen on the figure. Ductus choledochus is very wide. The shape of the caudate lobe 

 of the gnu resembles that of the same in Cephaloplms and Damaliscus according to 

 Garrod's^ figures of the same. The shape, presence or absence of the spigelian lobe 

 seems to be of little importance. 



The pancreatic duct seemed to join ductus choledochus. 



The s]jleen of the gnu (Pl. III fig. 3) has a very characteristic shape. It is elongate, 

 measuring 37 cm. in length. Both ends are rounded, but one end, the one fastened by 

 ligamentum p)hrenico-li(inale is soraewhat broader, I5V2 cm., than the other free end I2V2 

 cm. The former end is also thicker about 2V2 cm. It is thus rather thin. The elongate 

 shape of the spleen of the gnu reminds one of the same in the common ox, and differs 

 considerably from the short almost triangulär spleen of Ovis and Capra the short oval 

 one of Ovibos, Cervicornia and Giraffa. It might perhaps therefore be regarded as a 

 taurine characteristic. 



The cartilages round the nostrils are large and broad, but their general arrangement 

 is similar to the same in Bos. The most inferior of the nasal passages {meatus nasi 

 inferior) is quite wide, the two upper ones, on the contrary, very narrow. AJaxillo- 

 turhinale forms as well a lower as an upper conch which are both large (Pl. III fig. 4). The 

 height of both taken together is posteriorly about 4V2 cm. Nasotwhinale is long and 

 narrow, but its anterior portion more than a third, consists nearly exclusively of soft 

 tissue. It can almost be terrned linear as it is not at all expanded in a downward 

 direction posteriorly or at the middle as the same organ is in a common calf (conf. fig. 4). 

 It is not rolled upon itself and does not therefore form any real conch, but is only 

 curved downwards (nearly in a right angle) and overlaps posteriorly the upper conch of 

 maxillo-turbinale whei'e the latter, at its inner end, is broadest. In its simplicity the 

 naso-turbinal of the gnu resembles that of the muskox. Although in the latter it is 

 still less complicate only forming a longitudinal lamella which at its middle has its mesial 

 margin somewhat curved downwards. 



The ethmoturhinalia of the gnu diifer fi-om those of the common ox and muskox 

 in having their distal ends prolonged into lobes, partly tongue-shaped, partly in the shape 

 of a fungus and pro truding downwards and mesially into the nasal cavity so far that they 

 easily can be seen from the choanaj. Their situation and shape is shown on the accom- 

 panying figures (Fig. 4 and fig. 5, the latter showing the ethmoturhinalia in nat. size). 

 This is a difference from the condition found in the common ox as well as in Ovibos 

 and in other ruminants which I have had for comparison.
