All the specimens which have come under my notice are coloured 

 as above described. But Dr. Andrew Smith (Zool. South Africa) 

 observes, scarcely any two specimens are of the same colour ; some 

 are brownish black, variegated with white, and others almost entirely 

 uniform light reddish brown. 



2. POTAMOCHOERUS PENICILLATUS. 



Bright red bay ; face, forehead, ears and a large spot on the front 

 of the legs black ; edge of the ears, whiskers, streaks over and under 

 the eye, and a continued sub-crested streak along the middle of the 

 back white ; hair of the back short (black at the base), of the sides 

 and whiskers elongate ; tail very long, thick.

On the Horns of the Sanga, or Galla Oxen, of Gibba. 

 By J. E. Gray, Ph.D., F.R.S., V.P.Z.S. 



Dr. Gray brought before the Society a pair of horns of these 

 oxen, which the British Museum had lately purchased at the sale of 

 the property of the late Earl of Mountnorris, at Arley Hall. 



They are the pair mentioned by Mr. Salt in his * Voyage to Abys- 

 sinia,' at p. 258, 4to edit. 1844, where he observes: 



" There (Gibba) for the first time I was gratified by the sight of 

 the Galla Oxen, or Sanga, celebrated throughout Abyssinia for the 

 remarkable size of their horns. Three of these animals were grazing 

 among the other cattle in perfect health, which circumstance, to- 

 gether with the testimony of the natives, * that the size of the horn 

 is in no instance occasioned by disease,' completely refutes the fan- 

 ciful theory given by Mr. Bruce respecting this creature. 



* I have seen the specimen in the Basle Museum, and it is certainly the spe- 

 cies here described, only differing a little in the depth of the colouring. — J. E. G.
