ANATHANA, new genus. 



Type. — Tupaia ellioti Waterhouse, Proc. Zool. Soc. London, 1849, 

 p. 107, Plate, mammalia, 13. 



Diagnostic cliaracters. — ^A member of the mammalian family 

 Tupaiidse differing from typical Tupaia as restricted on page 30 in 

 havino- larger and better haired ears, coarser reticulations on naked 

 area of nose; unusually well-developed hypocones on the upper 

 molars, lower canines not projecting above the level of the adjacent 



teeth; relatively short and 

 heavy rostrum ; and a small 

 and inconspicuous fenestra 

 in zygoma. 



External cliaracters. — ^Ex- 

 ternally the genus ^naif?iona 

 is very simuar to Tupaia, 

 more like it than any other 

 member of the family. The 

 most tangible differences 

 are the distinctly greater 

 size of the lower portion of 

 the external ear in compari- 

 son with the upper portion, 

 due to a widening out of the 

 lower lobe, which projects 

 backward to a considerable 

 extent, and slightly for- 

 ward. The interior of the 

 ear is much better haired 

 than is the ear of Tupaia. 

 The rhinarium is squarely 

 cut across posteriorly as in 

 Tupaia, but is apparently 

 more coarsely reticulated 

 than in Tupaia and the 

 reticulations are more regu- 

 larly arranged. The footpads in Anathanu are essentially as they are 

 in Tupaia, but on the hind foot the internal proximal pad is per- 

 fectly distinct from the first interdigital pad in the few specimens 

 that have been suitable for making the observations; but in Tupaia 

 itself this distinctness of the two pads is often indicated, but usually 

 the two are fused to form one long pad. The pelage of Ajuithana 

 appears distinctly coarser and harsher than that of Tupaia, and the 

 grizzling of the colors is coarser, differences something like those seen 

 between Sciurus and Xerus. Nearly all the skins of Anathana 

 depending, however, a good deal upon the manner of arranging and
