During my stay in Egypt the Zoological Gardens received, 

 through the kindness of Capt. Burnet Stuart and Mr. Russell, 

 three specimens of a Hyrax from the Wadi Abu Kalifa, east of 

 Sohag, Upper Egypt. These animals lived only a day or two, and 

 on their death were handed over to me by Oapt. Flowei- together 

 with a skull and flat skin collected near the same locality by 

 Mr. Russell the previous autumn. 



A careful comparison of these examples with the British 

 Museum collection shows that while they agree with the cotypes 

 of Gray's H. hito'toni, they are easily distinguishable from spe- 

 cimens occurring in the Sudan and which are undoubtedly 

 referable to P. ri(ficeps. 



P. burtoni differs from rujiceps in having the crown of the head 

 similar in colour to the rest of the upper parts and not markedly 

 darker. The hairs surrounding the dorsal gland are also con- 

 colorous with the back, so that the yellow spot so conspicuous in 

 riificejis and some other forms is absent. 



ShiM. Mr. de Winton, referring to Burton's types, notes that 

 they show considerable variation but agree in the length of the 

 molar series. A comparison of a series of eight skulls from the 

 Sudan with the three cotypes of burtoni, shows that the teeth in 

 the first mentioned are constantly smaller than in the burtoni 

 specimens. 



All the examples now brought back, as well as the one from 

 Etbai presented a few years ago by Capt. S. S. Flower, and 



Measurements of Skulls.
