In låter periods of gravidity the right cornu, as usual, has become impregnated as 

 the condition in which it was found proved. 



Since it had been stated tbat in several species of antelopes the right uterine 

 cornu evidently has overtaken the chief function, and the left, even if it still con- 

 tributes to the nourishing of the foetus, has become to a certain degree reduced. it 

 appeared to be of interest to investigate whether this reduction also has been ex- 

 tended to other parts of the genital apparatus. For that purpose the ovaries of 

 some antelopes were measured and the following results obtained.

As can be seen from this, these measurements do not give any satisfactory proof 

 that the left ovary has been subjected to any reduction. 



Notes on the anatomy of the Warthog. 



On a pig of Warthog (Phacochcerus sp.) obtained near Escarpment station, Brit. 

 East Africa the following observations have been made. The specimen measured 

 about 36 cm. from snout to vent, but had, in spite of its small size, the intestinal 

 canal entirely filled with vegetable matter, and no trace of any milk could be detected. 

 It will appear from this that these pigs suck only for a comparatively short period 

 of their early youth. 



The general arrangement of the palatal folds of this animal is somewhat similar 

 to that of the domestic Pig as figured by G. Retzius. 1 The number of folds or 

 pairs of folds is about 23. They are not perfectly transverse as in the domestic Pig. 

 In the anterior portion of the palate each fold is curved with the convexity on the 

 front side, and with the lateral and mesial ends curved backwards. The posterior 

 folds become gradually straight, but they are a little obliquely arranged so that the 

 lateral end is behind the level of the mesial end. The three hindmost folds are not 

 continuous but formed by a series of papillae. 



The papillce filiformes of the tongue are minute, except at the base of the organ 

 behind papillce vallatce where they are large and conical. The papillce fungiformes 

 are very numerous and scattered över the whole of the upper surface of the tongue
