molar; the palate is longer and wider, and the basioccipital much 

 shorter and narrower. The difference in the size of this bone in the 

 two skulls compared is remarkable. 



"This is a rather extraordinary example. It has been in the 

 British Museum for a long time, was obtained from Mr. Bartlett and 

 is stated to have come from West Africa, no particular locality given. 

 Besides the many differences in the coloring of the pelage between this 

 specimen and examples of L. cephus, the rufous brow band at once 

 removes it from that species, and, seems to point to an affinity to L. 

 NEGLECTA and L. BRAZZ^ the only other species possessing this peculiar 

 mark, excepting the curious animal I have named L. insolita. It is 

 neither so broad as the brow bands of those species, and it is the only 

 character these animals have in common, so far as their style of 

 coloring is concerned. If there is any relationship between the present 

 species and either of the two mentioned it would of course naturally 

 be with L. brazz.e, from the Congo, as L. neglecta, the relative of 

 L. brazz.*:, comes from the White Nile region."
