CANIS PALLIDUS. 143 



We cannot recognize any good specific characters by which to 

 separate the V. edwardsi of Rochebrune from the C. pallidus of Ruppell. 

 Dr. Rocheburne rests its distinctness on its smaller size, but we have 

 seen again and again how great a difference may exist in this respect 

 between forms of the same species which inhabit different regions. 

 The form distinguished as V. edwardsi comes from Senegambia, whereas 

 the other type is an inhabitant of Nubia, Darfur, and Cordofan. 



Habitat. Eastern and Western Africa. 



Centimeters. 



Length from end of snout to root of tail 40'5 



of tail 32'0 



from heel to end of longest digit 10' 



of ear 5'5 



Another specimen has a larger body and a somewhat shorter tail, 

 but the length of the foot is the same. 



Cranial and Dental Characters. 



We have only met with an imperfect skull of this species. The 

 muzzle thereof is short, and the nasals do not extend so far backwards 

 as do the nasal processes of the maxillae. The lower jaw was wanting 

 in the skull examined.
