sheep. The absence of papillie on the lateral surfaces of the posterior portion of the 

 tongue in the gnu is a difierence from the condition found in the muskox and some Cervidce. 

 In Ovis the greater part, and in Capra the posterior half of this region is sraooth. 



Glandulce parotis of the gnu is a flattened (somewhat trihedral) body extending 

 from meatus auditorius externus about 12 cm. downwards in the anafle between the 

 masseter and the neck. The duct makes a curve round the ano-le of the mandible and 

 then ascends över the cheek opening in the cavum oris behind the papillaj mentioned 

 above, near the posterior margin of the second molar or nearly opposite the adjoining 

 borders of the iniddle and hindmost molar. The situation of the opening and the extension 

 of the duct is consequently the same as in Bos, but differs from the condition fonnd 

 in goats and sheep in which the duct extends across the masseter and opens further 

 anteriorly at the hindmost priBmolar or first molar. In Oinbos the situation of the 

 opening of ductus stens onianus is intermediate. It is namely found at the middle or 

 posterior half of the first molar. The glandulce buccales ventrales are well developed 

 forming a 6 cm. long mäss, 2 cm. broad behind, but tapering in front. 



The tonsils of the gnu have numei"ous openings, which is a difierence from the very 

 few (4 — 5) found in the muskox. In Saiga there seeins to be only »a narrow orifice» 

 according to Murie (1. c. p. 489). i 



The paunch of the gnu is very large. The distance from cardia to the end of the 

 dorsi-sinistral säck of the paunch when distended with water is about 60 cm. The same 

 dimension of the ventri-dextral säck is not much more, namely about 63 cm. The length 

 of the säcks is thus subequal. The greatest breadth of the latter säck measured from sidcus 

 longitudinalis dexter is 22 cm. The greatest breadth of the former measured from sidcus 

 longitudinalis dexter accessorius is 26 cm. The breadth is thus also subequal. Both sulci 

 are well developed, the latter almost more distinct than the former. The dorsi-sinistral 

 has a small (only 9 cm. in length) saccus ccecus which is quite distinct and rather pointed. 

 The saccus ccecus of the ventri-dextral säck is lai^ger (about 23 cm.) and more rounded. 

 The nearly equal size of the two great säcks of the paunch of the gnu makes it more 

 similar in this respect to the ox than to te sheep. The comparative ineasurements of 

 the reticulum and psalterium give another result. The diameters of the reticulum are 

 25 V2 X 18 cm. and those of the psalterium 19 \/2 X 13 cm. The former is thus larger. 

 This condition is different to that found in Bos, but agrees with the one found in Ouibos, 

 Ovis, Capra and Cervidce as well as in Anoa according to Heller (1. c. p. 26). It is thus 

 probably a more primitive characteristic which has been retained. The number of plica3 

 in the psalterium I have not as yet ascertained. 



The plicate part of the abomasus measures about 27 and the nonplicate about 

 16 cm. The number of folds seems to be about a dozen, thus much less than in Ovihos 

 and better agreeing with the corresponding number in Ovis, Capjra and Bos. The gnu 

 agrees also with the latter with regard to the great extension of the plicated tract com- 

 pared with the nonplicated. The first part of the duodenum is, as usual, dilated. The 

 general arrangement of the small intestine is as usual, but it ought to be observed that 

 the mesentery by which the jejunum is attached to the peripherical coil of the large 

 intestine is comparatively broad as it is also in Bos, unlike the muskox and the Ovine group.
