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.
