 species, as also Serranus variolosus Cuv. and some other spotted species from 

 the Moluccan Archipelago, have been from old times commonly linown to

 principally tropical, seas. Some also occur in the Mediterranean Sea ;

I^ote. — It is stated above, p. 37, that the sexes in fishes are 

 always distinct. This statement vt^ould appear to require modifica-
