Blind rat. Neotoma* 



* We find the fullest account of this rodent in Darwin's Origin of Species, where he refers to it in the follow- 

 ing words : " In one of the blind animals, namely, the cave-rat (Neotoma), two of which were captured by Professor 

 Silliman at above half a mile distance from the mouth of the cave, and therefore not in the profoundest depths, the 

 eyes were lustrous and of large size ; and these animals, as I am informed by Professor Silliman, after having been 

 exposed for about a month to a graduated light, acquired a dim perception of objects." (Page 142, Amer. edit., 1871.
