PrRoBABLE Hapits oF STENEOFIBER FossoR AND STENEOFIBER BARBOURI. 
Having carefully studied the remains of Steneofiber fossor and barbouri and com- 
pared them with recent fossorial and aquatic rodents, it is confidently believed that 
the two species under discussion belong to the fossorial kind. 
That the remains have been found inside of Demonelix many times and in 
different localities, is an interesting fact well worth considering. If, therefore, 
it is assumed that Dwmonelix is the cast of the habitation of these terrestrial and 
fossorial animals, it becomes easy to explain the great numbers of Damonelices in 
certain localities. The extensive areas on the western plains, which are occupied 
by the highly gregarious genus Cynomys are well known. These animals and their 
underground tunnels offer a splendid example for comparison with what may prove 
to be the preserved records of the habitations of, at least, two species of the genus 
Steneofiber. 
Nine species of Steneofiber have now been described from North America. I 
give here a synopsis of the characters, partially quoted from the original descrip- 
tions. In several instances, the types are so fragmentary that the specific characters 
are very few and unsatisfactory.
