TANA, new genus. 



Type. — Tupaia tana Raffles, Trans. Linn. Soc. London, vol. 13, p. 

 257, May, 182L 



Diagnostic characters. — A member of the mammalian family 

 Tupaiidse, similar to typical TujMia, differing in the possession of a 

 much attenuated snout and rostrum and a recession backward on top 

 of nose of the naked hairless portion. 



External characters. — The external form of Tana is essentially like 

 that of Tupaia with the exception of the elongated snout and the back- 

 ward extension of the naked area of the nose on top into the haired 

 area instead of being cut square across as in Tupaia. All the members 

 of the genus are characterized by the possession of a middorsal stripe 

 of varying length and width. This, however, is not diagnostic as one 

 member of the genus Tupaia, T. picta, has a well-marked dorsal 

 stripe, and Tupaia montana frequently has a broad, dark dorsal area. 

 The squirrel-like appearance of treeshrews in general is still carried 

 out by the genus Tana, which may be compared with the long- 

 snouted genus of squirrels, Rhinosciurus Gray.^ The mammse are 

 2-2 in number. (See figure 2, p. 31, plate 6, figs. 1 and 2.)
