8. Macroxvus. 
Head moderate, short; nose rounded; ears ovate, covered 
with short adpressed hairs; front edge of the cutting-teeth 
compressed, smooth. Limbs free. Tail as long as or longer 
than the body and head, covered with long spreading hair. 
_ M.F. Cuvier, in the ‘ Dents de Mammiféres’ and in his paper 
on the skulls of Sciuride in the Memoirs of the Museum, pro- 
posed a genus under the name of Macroxus for Sciurus vittatus 
of Asia and Sciurus estuans of Tropical America. It is very 
indistinctly characterized ; and Lesson has referred to the genus 
sundry species having little relation to each other. As it is 
desirable to separate the squirrels with simple ears, I have 
adopted the name, and defined it as above. It is a natural 
group, containing many Asiatic, African, and American species. 
The Asiatic Macrozi may be thus divided :— 
I. Large size. Tail much longer than the body and head. Nos. 1-3. 
Il. Medium size. Back with black longitudinal stripes. No. 4. 
III. Medium size. Sides of the body with a black longitudinal 
streak. No.5. : 
IV. Medium size. Sides of the body with a pale or white longitu- 
dinal streak. Nos. 6-13. 
V. Medium size. Sides of the back with two pale streaks ; lower 
broad, diffuse. No. 14. 
VI. Small size. Back with three or five white or pale longitudinal 
stripes. Nos. 15-18. . 
VII. Medium or small size. Back grizzled, without either dorsal 
or lateral stripes. Nos. 19-38. 
I. Large size. Tail much longer than body and head. Rukaia.
