[66] Aplysia punctata, of which two specimens, one viewed sidewise, and the other mounting an angle of rock, showing the front of its head, are depicted in Plate [XVI.] Sowerby applied the name of “hybrida” to the species, and Forbes and Hanley have adopted it; but even the inflexible law of priority does not warrant the perpetuation of a name which is glaringly absurd, and expresses a manifest contradiction; for if the creature were a hybrid, it would not be a species, and not be entitled to a specific name.
