76/193 Oken was right (as it turns out), and Lepas aurita and vittata must form together one genus. In the "Monograph on the Cirripedia" (Lepadidae) the names used are Conchoderma aurita and virgata.) (I leave out of question a multitude of subsequent synonyms.) Now I suppose I must retain Conchoderma of Olfers. I cannot make out a precise rule in the "British Association Report" for this. When a genus is cut into two I see that the old name is retained for part and altered to it; so I suppose the definition may be enlarged to receive another species--though the cases are somewhat different. |
