Of the two forms that occur in the island, both the type, 

 and the specimens obtained for the British Museum by 

 Mr. T. Thomson, and mentioned in Gray's List of 1843, 

 most nearly match the darker form, that found high up on 

 the Clarence Mountains. 



6. Hello sciiirus rufobrachium acticola^ subsp. n. 



Like true rufobrachium, but paler througliout. 



General colour above grizzled grey, with much less of the 

 brownish tone found in rufobrachium. Under surface pale 

 brownish, the chest and inguinal regions whitish. Fringes 

 of forearms strong buffy. Hands grizzled buffy. Tail 

 without buffy suffusion on its basal half.

Collected 23rd December, 1903, by Mr. E. Seimund daring 

 the Fernando Po Expedition. Twelve specimens. 



This comparatively pale form was found by Mr. Seimund 

 close down to the beach. It has the appearance of being an 

 inhabitant of an area less saturated than the high ground 

 where true rujohrachium occurs.
