This brain is exceedingly small in proportion to the size 

 of the animal, and yet its small, short cerebral hemispheres 

 present a series of deep sulci, which conform to the most 

 typical mammalian pattern. In many points of detail this 

 pattern resembles that of the Three-toed Sloth, while in 

 other respects it resembles that of the Armadillos.
