THE SLOW-PACED LEMUR. 
LORIS TARDIGRADUS. GeOFF. 
In an early Memoir on the family to which this sin- 
gular little creature belongs, M. GeofFroy-Saint-Hilaire 
divided it for the first time into those minor groups of 
which it was most obviously composed. But he has 
subsequently carried the principle of subdivision to a 
still greater extent by separating the present species 
frem the Slender Loris, with which he had previously 
associated it, in order to form of it and of some other 
doubtful species a new genus under the name of Nycti- 
cebus. We cannot perceive any sufficient grounds for 
thus disuniting two animals so intimately allied to each 
other, and differing in no more essential characters 
than the somewhat greater length of the nose and of 
the limbs in the one than in the other. It is for this 
reason that we prefer his older arrangement, and pro- 
ceed in accordance therewith to describe our animal as 
a species of Loris, a well marked, circumscribed, and
