What catfish is this?

[Stone Like Fish]

Saw this in a members post in the Knifefish section, what are they? I've seen them before but have no clue!

It's one of the larger "dolphin" catfishes from the woodcat family. Could be from the genus Ageneiosus http://www.planetcatfish.com/common/genus.php?genus_id=105#1471
