Bufonidse 



Bufo 'cognatus escaped one morning from its moss-garden in a 

 building in Rhode Island. That day repairs had been begun on a 

 cement floor in the basement of the building. In the afternoon of 

 the day, while workmen were continuing to remove the cement 

 floor — which had been put down seven years before — they 

 came upon a fat toad just fitting a burrow under the floor. Ex- 

 citement followed, with many stories of toads found in similar 

 situations where they had been for more than seven years. If 

 the toad had not turned out to be the lost Bujo cognatus from 

 Colorado, and had been a native of Rhode Island, there would 

 have existed no proof that it had not been there seven years 

 instead of a few hours.
