170 MAMMALIAN DESCENT. [LECT. VII,

 I find this state of things in a sub-adult specimen of the 

 lesser kind (Hemicentetes), and the smallest kind (Micro- 

 yale) ; my specimen of the latter, M. longicaudata, has a 

 tail nearly twice as long as its body, which is very 

 curious for a member of the Tenrec family, the main
