Passing to tlie forms occurring to the east of the brightly- 

 marked maculatus and hardyi^ it might be convenient to 

 commence with the squirrels of Fernando Po, that being 

 the place where the first members of the group were obtained. 

 In that island a considerable number of specimens were 

 obtained by Mr. Seimund on tlie Fernando Po Expedition 

 of 1903-4, and a study of these shows that the island 

 contains two forms, a highland and a lowland subspecies.
