myself, on both occasions lying dead on a path in the forest country of 

 Bustar in 1857.* 



Mr. Blyth places this field-rat among the field-mice, but, if it does not 

 belong to the true rats, it appears to me related to the Mus meltada 

 group, and M. jjlurimammis may be somewhat allied. Another similar 

 rat is described iu the same place as 2fus morungensis, Hodgson, 

 *' Hairy covering of the body above minutely striated with black and 

 rufous hairs nearly equally mixed, giving the animal a blackish rufous 

 aspect ; abdomen and extremities paler, rufescent gray. Body propor- 

 tionally robust and stout ; head lai-ge and thick, and muzzle short and 

 abrupt ; ears large and rounded ; tail cylindi-ical, gradually tapering to 

 the point and delicately annulated, equal in length to body and head ; 

 fur abo\'e soft, hairs longer than in plurimammis. Length, head and body 

 4| inches ; tail 4|. From the Nepal Terai and adjacent plains." 



Next come a group of rats with the tail usually fully as long, or longer 

 than the head and body. Some of these have quite arboreal habits, 

 building nests among the branches of trees, among the rafters of houses, 

 tfec, and not burrowing in the ground.

The Tree-rat. 



jDescr. — Above reddish-brown, or rusty-brown, with a few long 

 bristles intermixed ; beneath dull-whitish, or pale-rusty with a hoary 

 tinge, or pale grayish-brown ; tail as long, or a little longer than the 

 head and body ; feet pale fleshy ; ears rather long, and head somewhat 

 lengthened. 



Length of one, head and body 9^- inches ; tail 9 : another measured 8 J ; 

 tail the same : and another 8^ inches, tail 9|. 



Some have the upper parts dark brown, with only a slight rufescent 

 tinge. 



This rat appears to be found throughout India and Ceylon, not habi- 

 tually living in holes, but coming into houses at night ; and, as Blyth 



* These were unfortunately lost during the Mutiny, with many other valuable 

 specinicus from the same district.
