Generic Characters. — Body elongated, slender, covered with a series of indu- 

 rated plates arranged in parallel lines ; head long; both jaws produced, united, 

 tubular ; no ventral fins. In the species of the first division, an elongated 

 pouch under the tail in the males only, closed by two folding membranes. 



In the species belonging to this family the jaws are 

 united, forming a tube more or less cylindjical. The gills, 

 instead of having the pectinated appearance so well-known 

 to exist in the fishes previously described, are separated into 

 small rounded tufts, which are arranged along the branchial 

 arches, and the fishes of this family are therefore called 

 Lophobranchii. 



* The family of the Pipe-fishes.
