no conspicuous posterior canines; maxillary not produced backward 

 from angle of mouth; gill-membranes united, free from the isthmus. 

 Dorsal flu long and low, chiefly comiiosed of spines; some of the ante- 

 rior spines often different from the others, longer or shorter, and set 

 farther ajDart; anal fin low, with 2 spines; ventral fins jugular, of 1 

 spine and 2 or 3 rays; caudal flu truncate; branchiostegals 6; air- 

 bladder and pyloric cceca absent; viviparous. Inhabiting rock-pools 

 among algte, in warm seas. Our two species are very different, and 

 represent opposite extremes in this large and varied genus. (zAiVocr, a 

 name of some sleei)y fish; from xAtVvj, a bed.)
