The songar is of a grey colour ; has a thick

line runs along its back ; its sides are spotted with 
white ; its belly and legs are white. They are 
found in the same country with the sand rat. 
Dr, Palla3 kept some of them a great while, 
They grew familiar, would feed from his hand, 
lap milk, and, when placed on a table, shewed 
no desire of running away. They were slower 
in all their motions than the other species ; washed 
their faces with their paws, and sat up to eat ; 
wandered about during the day, and slept all night 
rolled up. They seldom made any cry ; and, 
when they did, it was like that of a bat. It is a 
native of Siberia.
