1 Tt. is in most cases a quite useless task to try to elucidate the species of 
Dorides of the elder authors; their examinations were all too superficial 
and their descriptions don’t contain the data necessary for their verifica- 
tion. The best way would be to wholly cancel these names (D. fusca, M.; 
D., levis, L., etc.) which have given later authors so much trouble. On the 
Doris fusca of O. Fabricius, Morch has even formed a genus Proctaporta 
(Rink. Grénland. I, 1857. Tillag. 4, p. 78), that must be cancelled, too. 
2 The short statements of Lebert about form and color of the animal 
examined by him can scarcely entirely prohibit the identification of it with 
the species described by Alder and Hancock. The figures of the (tongue) 
teeth given by Lebert, rough as they are, suffice, on the other hand, to 
secure the identification with the D. swbguadrata, or at least with a nearly 
related species.
