Two specimens from the Jambu estuary. 
‘ This is the least terrestrial of the mud gobies which we saw in 
Malaya, and is obviously less highly specialized for an amphibious life than 
any species of Boleophthalmus or P eriophthalmus ; but it frequently wriggles 
along the mud some yards away from the water, and its powers of “ walking,*’ 
or rather hopping, on land, though less well-developed than those of its allies, 
are by no means absent. At the mouth of the Patani River, at dead low 
tide, numerous individuals line the water’s edge, and by some muscular effort 
raise their heads and bodies into the air almost vertically, remaining poised, 
as if standing upright on their tails for an instant, and then falling prone on 
the liquid mud. This curious manoeuvre, probably executed in attempts to 
capture flies, causes a peculiar sound, which can be heard all along the shore.* 
15. Periophthalmus koelreuteri (Pall.) 
Gobius koelreuteri Pall.^ Spic. vii, p. 8, vol. 2, fig. i. 
Eight specimens, one-and-a-half inches to three inches long. 
First dorsal = 10-14 ; second dorsal = 13-14 ; anal = ii. Pelvic fins 
in every specimen completely separate. 
‘ P, koelreuteri^ at any rate in youth, appears to prefer mud of a rather 
firmer consistency than that affected by P, phya^ and to enjoy climbing on 
roots and stones, the difference in its habits rendering it comparatively easy
