of the Sciurus Prevosti Group. 169 
(7) Sccurus Prevostid borneoensis, from Pontianak, S.W. 
Borneo. 
(8) Sciurus Prevostit redimitus, locality unknown. 
(9) Sciurus Prevostti Rafflesii, trom Sumatra. 
(10) Sedurus Prevostit rufogaster, from China (doubtful). 
With regard to the last two forms, there is not sufficient 
material to judge whether they be distinct or not. The 
types, which are the only specimens I have had an oppor- 
tunity of examining, seem to me identical, and it is quite 
probable that they both came from the same place, as the 
exact locality of rufogaster is very doubtful. 
In addition to the forms mentioned above, Mr. G. Miller, Jr., 
has recently described * two other insular forms, viz. :— 
Sciurus mimellus, from Pulo Wai, ‘Tambelan Island. 
Sciurus mimiculus, from Ste. Barbe Island. 
They are distinguished from Se. Prevostid typicus by the 
narrowness of the white band, especially on the thighs, and, 
as might be expected, are most nearly allied to Se P. 
navigator of this paper. 
Se. mimiculus differs from Se. mimellus only in its smaller 
size.
