XVII. — On Dendrohyrax Bakeri, a new Species from Tropical 

 North-eastern Africa. By Dr. J. E. Gray, F.R.S. &c. 



Sir Samuel Baker, K.C.B., collected during his travels a 

 Dendrohyrax at Latiko, in lat. 3° 0' N., in tropical Eastern 

 Africa, and has presented a skin with its skull to the British 

 Museum. The skull shows that it is a species of the genus 

 Dendrohyrax, and is peculiar in that genus for having the 

 back edge of the orbit incomplete, whereas in the skulls of 

 the two species of this genus which we have in the British 

 Museum the bony orbit is complete. 



The lower jaw is moderately narrowed in front, with a 

 straight lower edge, and rather dilated behind, somewhat 

 as in Dendrohyrax dorsalis — and very different from that of 

 Dendrohyrax arhoreus, which is dilated, and has a rounded 

 outline to the lower edge. 



The fur is short, uniform, soft, and brown, grizzled with 

 pale tips to the hairs, very unlike the long, soft, fluffy fur of 

 Dendrohyrax arhoreus from South-east Africa, and the harsh 

 dark brown fur, with a large white dorsal patch, of Dendro- 

 hyrax dorsalis from West Africa. 



It is certainly a species that has not been hitherto entered 

 in our catalogues ; I therefore propose to call it Dendrohyrax 

 Bakeri, after its discoverer. 



The skull in many respects, especially in the incompleteness 

 of the orbits, agrees with a skull without lower jaw in the 

 British Museum, which we received in 1858 from the museum 

 of the Zoological Society, without any special habitat, and
