in consequence of Heller's statement possible that t lie exterior lobu- 

 lation of the ^noa-kidney makes itself more conspicuous in a some- 

 what later stage. The structure of the JLwoa-kidney, as it appeared 

 on my preparate described above, is a characteristic of considerable 

 importance from a classificatory point of view. As this characteristic 

 of having at least interiorly perfectly lobulated kidneys among the 

 Cavicornia is shared only by the common ox and its nearest relatives 

 it may be regarded as a true bovine characteristic indicating affinity 

 and common origin. 



As the animal dissected was not fully adult the genital organs 

 were not fully developed and in addition to this they were, before they 

 fell into my hands, damaged as they had been roughly cut out from the 

 body of the dead animal. Some notes about them may nevertheless be 

 appended. The testicles are small. Together with the epididymis they 

 measure about 4 ! 2 cm. in length and 2 cm. in thickness. The thick- 

 ened terminal portions of casa deferentia are comparatively long, 

 about 5 cm. in length by 5 mm. in thickness, and the interior of the 

 same within the muscular coat has a plicated and spongious-looking 

 appearance. The colliculus seminalis is well developed and the openings 

 of the ductus ejacalatorii are protected by broad plicae and in addition 

 to this by a double papilla on either side at the distal end. The uesi- 

 cuke séminales are small, but have the elongate shape of those of the 

 common ox. Their length in this young Anna is about 24 mm. and 

 their thickness about 8 mm. They lie straight and are not doubled 

 up as. for instance, is the case in AnUlope cervicapra. 



The glanduke cowperi have been cut away in this preparate and 

 cannot therefore be described. 



The penis has a short flexura sigmoidea. The end of the organ 

 (fig. 10) is bluntly pointed and has no urethral prolongation as may 

 be seen on the figure (fig. 10) wherein we find a certain likeness to 

 the same organ of Bos taurus. The length of the in the prepuce in- 

 cluded glans is about 38 mm. The almost slit-like opening is situated 

 on the left side about 4 mm. from the blunt tip. Dorsally towards the 

 right side there is a prominent cushion although not so strongly deve- 

 loped as in the Nilgai with the penis of which that of the Anoa also has a 

 certain likeness. The asymmetry of the organ with the urethral opening 

 on the left and the dorsilateral cushion on the right side is an ancient 

 characteristic although the urethral prolongation has been reduced. 

 The penis of the Anoa is, however, of a more primitive ruminant type
