retreats rapidly downwards. In order to collect specimens, I 

 searched for oval orifices in the mud ; and having found one, a spade 

 was plunged very deeply in and the mud turned up, the hands then 

 being used to go deeper ; yet, still, in many cases, the creature was 

 too quick for the diggers."

[Eeceived September 17, 1878.] 

 (Plates LI.-LIII.) 



This list comprises the Lepidopterous portion of the collection 

 made on and around the Moulayet range in Upper Tenasserim by 

 Mr. Limborg, who was accompanied by Mr. Wood-Mason's native 

 collector, Motiram. The party proceeded, about the middle of 

 December 18/6, from Moulmein up the Houngduran, collecting as 

 they went along to the Hills, on and around which, and along the 

 banks of the river leading to them, the whole collection was made.
