Concerning this frog SJOSTEDT has communicated from his diary the following. 

 This is the most common frog of the district and is especially incredibly numerous 

 on the low lands round the Natron lakes between Kilimandjaro and Meru and at the 

 rivers and rivulets there. They sit often in the grass on land some way off from 

 the water and take very long leaps. Very quickly it makes a long jump out from 

 the grass and dives down again in the same but as a rule it does not stay but con- 

 tinues its jumping further away to seek shelter and safety. If it is near the water 

 it takes some long leaps and disappears like an arrow in the same. In some places 

 they are literally swarming and form the main food of many of the birds frequent- 

 ing these lakes in great numbers.
