 above the level of the ground, and a charge of shot 

 fired into the moving soil will usually be effective 

 in killing the animal. Bright moonlight nights are 

 the best times for this operation. 



These mole-like rodent animals are grouped under 

 two genera, and the genus to which the various 

 species belong, may at once be determined as follows : 



Genus : Bathyergus 

 SAND MOLES 



TOES of the fore-feet with long and strong claws, the 

 claw on the second toe being considerably longer 

 than the rest. On thq hind-feet the claw on the 

 third toe is the longest. Upper incisor teeth 

 grooved. 



Genus : Georycbus 

 BLESMOLS AND MOLE RATS 



THE animals under this genus are smaller in size than 

 those of the preceding genus, but closely resemble 

 them externally. They differ chiefly as follows :
