Dr. J. E. Gray on a new Species of Bush-Goat. 63 



picture in the British Museum, the description of eye-witnesses, and 

 the existing remains warrant us in attributing to the bird. It is 

 difficult to assign a motive to the artist for thus magnifying an 

 object already sufficiently uncouth in appearance " (' The Dodo/ 

 &c. p. 31). Is it not possible that the artist may in this painting 

 have taken a life-sized portrait of the large species (Didus nazarenus, 

 Bartlett) to which these bones belong ? 



In conclusion, I have to state that I should be very glad if these 

 remarks were the means of exciting further search for the remains 

 of the Dodo and its allies. In Rodriguez the bones must be far 

 from scarce, and, as the present instance shows, they may be found 

 with little trouble. My brother picked up two of them, as I have 

 said, in a cave during a very hasty visit. It is a matter of the 

 greatest regret that a regularly organized search is not instituted by 

 some resident in that island, or by some visitor to whom time is no 

 object. We may depend upon it that a rich reward awaits the care- 

 ful explorer of the Mascarene caverns and alluvial deposits. 



Notice of the Skull of a New Species of Bush-Goat 

 (Cephalophus longiceps), sent from the Gaboon by 

 M. Du Chaillu. By Dr. J. E. Gray. 



M. Du Chaillu has lately sent to the British Museum several skins 

 and skeletons of the Gorilla (showing how abundant it must be at 

 the Gaboon), the skin and skeleton of a Chimpanzee, three skeletons 

 of the African Manatee, and the head of a Bush-Goat or Cephalo- 

 phus. 



The skull of the Cephalophus on examination proves quite distinct 

 from any that has previously occurred to me ; and as it indicates the 

 existence of a large species of the genus, I have sent a notice of it to 

 the Society in hope that we may before very long have a complete 

 specimen of the animal to describe. 



Cephalophus. 

 Section I. Horns decumbent. 

 Cephalophus longiceps. 



The skull elongate ; face elongate, compressed in front of the 

 eyes ; the nose in front of the eyes narrow, sides only very slightly 

 tapering ; nasal bone very long, produced between the frontal be- 

 hind, much longer than the medial suture of the frontal. The horns 

 elongate, conical, diverging at the tips, decumbent, in a line with the 

 forehead ; forehead convex between the orbits. 



Length of skull 10 inches 9 lines; width at zygoma 4 inches 

 7 lines ; length of horn-cores 5 inches ; length of lower jaw 9 inches. 



The only species with which the animal can be compared, on ac- 

 count of its size, is C. sylvicultrix ; but the skull of the latter is 

 short and ventricose, and that of C. longiceps is elongate and slen- 

 der. The face of C. sylvicultrix is short, and the nose between the 

 impression for the suborbital glands broad and tapering ; the fore-
