 This genus differs from Salarias in the presence of posterior canines in one or both jaws. In both 

 genera the teeth are loosely inserted, and the gill-membranes form a broad fold, free from the isthmus. 

 The case of Altinis, quoted by Lacepede from manuscripts of Commerson, is parallel to that of 

 Ziiiwtus (vs. Pomacantlius), and of Anlennanus (vs. Hislrio), and in all the?e cases we allow prece- 

 dence to the earlier name.
