Body moderately elongate, compressed, covered with small, cycloid, 
imbedded scales; belly and head naked. Eyes small, almost superior. 
Gape wide, the maxillary in the adult inordinately developed, prolonged 
backward to the base of the pectorals; its posterior part a cartilaginous 
expansion, connected to an expansion of the skin of the lower jaw, 
thus forming a channel backward from the month, almost exactly as 
in the Blennioid genus Neoclimis and the Trachinoid genus Opistliog- 
nafhus. Teeth small, even, in broad bands. Dorsal fins 2, the second 
high, the first of G very weak spines, none of which are exserted; cau- 
dal rounded; pectorals large; isthmus broad. Singular little fishes, 
in brackish waters, Imrrowing in the mud.
