PERODICTICUS 41 



Poor Potto ! not a very flattering portrait indeed, but the earliest 

 authors not infrequently indulged in similar descriptions of strange 

 and little known animals. The Potto is strictly nocturnal in its habits 

 and would not be likely to go "anything distant" during the daytime, 

 and although its movements are slow and performed with deliberation, 

 it would survive a sufficient length of time to reach a new food supply, 

 and as it is a dweller of trees it is not likely to attempt any considerable 

 journey on terra firma.
