212 HYRAX STAMPFLII. 



incisors rounded in front ; at a small distance from the back 

 edge of the upper incisors there is on each side a small hole, 

 indicating the second (deciduous) upper incisor : lower in- 

 cisors trilobed , separated into pairs. The upper grinders in 

 nearly parallel series , the lower ones parallel. The skull 

 presents many differences with that part of the skeleton 

 of Hyrax dorsalis , better to demonstrate by figures than 

 by long descriptions: I hope to give some figures of this 

 skull in the Catalogue ostéologique du Muséum d'Histoire 

 Naturelle now in the press, and to exhibit the anomalous 

 form of the interparietal, the form of foramen magnum^ 

 of the coronoid process ') and of the a7igle of the lower jaw. 

 Hah. Liberia , Junkriver , Schieff'eliusville. Collected by 

 Mr. F. X. Stampfli, 3rd February 1886. It has been captured 

 in a cavern of a very high rock , called Chap-hill , oppo- 

 site Schieff'elinsville. 



1) I express my thanks to Mr. Oldfield Thomas of the British Museum, 

 who made for me a drawing of the coi-onoid process of the skull of the 

 type-specimen of Hi/rax dorsalis Fraser. This skull has been figured in 

 Gray's Hand-list of the Edentate, Thick-Skinned and Euminant Mammals, 

 1873, pi. XIII, fig. 1, but in that figure the part in question is concealed 

 by the zygoma.
