so that scarcely a stalk of rice escaped them. I met with two of these 

 animals, swimming the Tenasserim where it is more than a quarter of a mile 

 wide, and succeeded in capturing one. The animal is ahout five inches from 

 the nose to the end" (base ?) " of the tail, of a slim and nimble appearance, the 

 belly white, and the rest a mouse colour. During the rains, when the river 

 is much wider and more rapid, these Eats crossed in columns, as the people 

 say, so abundantly that a boat, in passing through, caught bushels of them. 

 They only make their appearance at long intervals, like the locusts of other 

 places. It is said to be from twenty to thirty years since they visited the 

 country before, to any great extent."

Schwe Gyen, valley of the Sitang river. 



A particularly well-distinguished species, of which there is an unmis- 

 takeable specimen marked from the Philippines in the Derby Museum of 

 Liverpool. Mason suspects this to be the field Mouse of the Karen districts.

Valley of the Sitang. Mason notices a "very familiar little Mouse in 

 the houses at Tounghoo," which he never saw in the Tenasserim provinces;
