direction, as in FAaphus and our affinis, species to which the present 

 one is also allied by its short tail and moderate suborbitar sinus. 



Cervus Dimorphe, mihi. Deer with moderate, pale, smooth horns. 

 Axine in the general style, but more bent in the middle of the beam, 

 more divergent, and possessed of only one basal antler, which is 

 directed very forward ; small, or moderate, and vertical suborbital 

 sinuses ; interdigital pores ; broad spreading ears and short stag-like 

 tail. Stature and aspect mediate between the Axines and Rusans. 

 In youth bright fawn-red, spotted with white ; in age nigrescent bay 

 with blackish neck and belly ; a dark list round the muzzle and white 

 chin ; limbs pale. Habitat the Saul forest. — Journal of the Asiatic

ON A SUPPOSED NEW SPECIES OF HIPPOPOTAMUS. 

 BY S. G. MORTON, M.D. 



It is about six months since I received from my friend Dr. Goheen 

 an extensive series of skulls of mammiferous and other animals from 

 Western Africa : they had been obtained by him during a residence 

 of several years at Monrovia, where he had officiated as colonial 

 physician ; a situation which gave him great advantages for procuring 

 the natural productions of that region. Among these crania were 

 two of a hippopotamus of small size, from the river St. Paul's. 

 Although nothing could be more manifest than the difference be- 

 tween the head of this animal and that of the common species, I 

 have hesitated to publish it, from a fear that some one else may 

 already have done so ; for I could hardly convince myself that so 

 remarkable a species was wholly unnoticed in the systems. Having, 

 however, searched the latest European works on zoology without 

 finding any account of this interesting animal, I venture to submit 

 the following facts in relation to it : — 



Hippopotamus minor.

These measurements have been taken from a very old individual, 

 in which the sutures are entirely obsolete, and the teeth worn almost 

 to the level of the jaw ; and the contrast in size between this and the 

 large or common species (familiar to every one as the H. amphibius, 

 but recently divided into two species, the H. capensis and H. sene-
