 in the flesh : — Head and body 188 mm. ; tail 57 ; hind foot 29 ; 

 ear 10. 



A skull of T. s. ibeanus in the Museum collection, obtained by 

 Capt. Speke, dates from 1863. Since then specimens have been 

 received from Kilima-njaro (Hunter 4' Baxter), Bukoba (Emiri), 

 Maehako's (Hinde), Mumias, Kavirondo (Ansorge), and now the 

 present specimens from Nairobi.
