" The type specimen was caught at Okwa, which is about 

 lialfway between the Molopo River and Lake Ngami, riglit 

 in the middle of the Kalahari. It ran out of a big log which 

 liad been thrown on the fire at night, and I fortunately 

 managed to catch it as it passed me."

" In Ngamiland there is a periodical flood which occurs in 

 the dry season, and besides filling up the vast Okovango 

 marshes and Lake Ngami inundates hundreds of square miles 

 of dry sandy country and acacia-forest. As the water ad- 

 vances over the flat country the small mammals are driven 

 back, and towards the height of the flood in many places 

 around the marshes the whole surface of the ground for miles 

 is covered all over with mouse-holes, where the fugitives take 

 up temporary residence until the floods subside. The natives 

 assured me that lions sometimes hunt the mice in these 

 colonies and dig them out and eat them, as they are then very 

 fat, it being winter."
