14 EINAR LONNBEEG, ANATOMICAL NOTES ON EAST AFRICAN MAMMALS. 



The psalterium was triplicate. 



The dimensions of the liver were 31 X 21 cm., and both the main lobes were 

 of about equal size. Lobus caudatus capped the kidney and lobus Spigelii was 

 tongue-shaped. 



The spleen was exactly twice as long as broad, 42 Va X 21 cm., rounded at both 

 ends, one of which was a little broader than the other. 



The colon formed an ansa proximalis before it entered the spiral which con- 

 sisted only of 1 Vz centripetal and 1 centrifugal coil after which it, in connection with 

 the- jejunum, made a peripheric coil. 



The kidney was exteriorly smooth but consisted of several pyramides. 



An ElaJtid {Taurotragus oryx patter sonianus) had, according to notes made in the 

 field, the papillse of the paunch broad and large. The contents of the ventricle were 

 as well leaves and twigs as grass. The psalterium was triplicate with slight indica- 

 tions of a fourth series. 



The dimensions of the liver were about 52 X 25 cm. The breadth of the two 

 main lobes was about 21 and 26 cm. resp. Lobus caudatus is large and broad, about 

 tongue-shaped with the dimensions 15 X 9 cm. The gallbladder is large hanging 

 entirely outside the edge of the liver, about 10 cm. from the main fissure. 



The spleen is thin about tongue-shaped in outline with the dimensions 39 x 13 

 cm. Its shape may thus be termed almost taurine, and it differs widely from the 

 triangular spleen of the Ovine group and of some Antelopes (e. g. Antilope, Gepha- 

 lophus etc.), or the short elliptic primitive shape. 



The colic spiral consisted of 3V2 coils in either direction. It is thus well de- 

 veloped which was to be expected in such a large animal which, at least partly, must 

 be contented with coarse food. 



The kidney was quite smooth without any trace of exterior lobulation. 



The Somali Giraffe {Giraffa c. reticulata) has a pentagonal papilla incisiva with 

 the base anteriorly, and the opposite angle behind. On the sides of this papilla and 

 close behind the same the palatal folds are irregular and divided into irregular lobes 

 or flat warts. Further behind, however, the palatal folds soon become plainly de- 

 veloped. Already the third behind the papilla incisiva is rather evident, and from 

 the fourth and backwards they become gradually broader and longer. They have 

 all of them a l<dbulated posterior margin. These lobules are broad and thick on the 

 anterior folds, but become more pointed and thinner behind. About 15 folds can 

 be discerned, the 10 anterior of which may be said to have thick and short lobules, 

 although the change to those with thin, pointed ones is gradual. Between the 10 

 anterior folds one, or sometimes two rows, of larger or smaller papillae are intercalated. 

 The five posterior pairs of folds are more distant from each other, partly as much 

 as 2 cm., obliquely arranged, almost alternating, with sharply pointed lobules. Those 

 of the last palatal fold end just in front of the foremost premolar. The anterior 

 portion is partly, the posterior entirely pigmented. 



The conical papillae covering the inside of the buccal tract are very large. On
