passing into orange towards the white inner side (the difference 

 between the red-brown and the orange being due to the circum- 

 stance that in the former case the bases of the hairs are ash-grey, 

 in the latter white). The colour of the legs after Eidgway 

 (Xomencl. Col.) is tawny (pi. v. fig. 1) with a wash of Chineseorange 

 (pi. vii. fig. 15). 



Length of body 46 cm., tail ca. 60, height at shoulder ca. 32, 

 height at hip ca. 35 cm. 



The appearance of the cranial sutures, the teeth, and the bones 

 prove that the animal is not an old one, though it appears to have 

 attained its full size. As it \vas brought over from Africa in the 

 year 1SS7 and died in 1891, it was at least five years old.

4. Report on the Collection of Reptiles and Fishes made by 

 Dr. J. W. Gregory during his Expedition to Mount 

 Kenia. By Dr. A. Gijnther, Keeper of the Zoological 

 Department, Britisli Museum.

(Plates VIII.-XL) 



Considering the difficulties Dr. G-regory had to overcome in 

 attending unaided to the various duties of a scientific traveller, 

 and the fact that the formation of zoological collections was but 

 a secondary object of his expedition, we may be very well satisfied 

 with the series of Reptiles and Kshes which he was able to bring 

 home. 



The Reptiles are referable to 38 species, the majority being well- 

 known forms of the Central East-African Fauna, but they never-

 of the several species, inasmuch as the collector took great care in 

 noting the localities where the specimens were obtained, and
