|
Trionxchidae Apalone spinifera Sternotherus odoratus Chelydra serpentina Graptemys geographica Chrysemys picta The author shows that the 'interesting,' and apparently more intelligent forms of tortoises, cannot be kept in captivity and introduced to the various forms of 'problem boxes' now so common in the studies of animal behavior. The only other method left for studying these animals is the more laborious one of watching them 'in their daily rounds and occupations.' If one does this for a long enough period of time one becomes able, so the writer assures us, 'to diagnose their dispositions and comparative intelligence.' The author shows that each of the five varieties studied has a definite 'species character.' He shows also that there is not only a species character but a sex and an individual character as well. The author has done his difficult and trying task with a great deal of thought and care. This investigation gives us a mass of useful data on the habits and instincts of the most important forms of tortoises.
