280 TELEOSTEI. ACANTHOPTEETGII. 



These fishes, from the muscular development at the base of the 

 pectoral fins, are able to use them for progression on mud or for 

 climbing. It is most curious to see P. schlosseri along the side of 

 the Burmese rivers ; at a distance the fishes appear like large tad- 

 poles, stationary, contemplating all passing objects, or else snapping 

 at flies or insects ; suddenly startled by something, away they go 

 with a hop, skip, and a jump, either inland among the trees, or on 

 to the water like a flat stone or a piece of slate sent skimming by 

 a schoolboy. They climb on to trees and large pieces of grass, 

 leaves, and sticks, holding on by their pectoral fins exactly as if these 

 were arms. Now and then they plant these firmly as organs of 

 support, the same as one places one's elbows on a table, then they 

 raise their heads and take a deliberate survey of surrounding 

 objects.
