tWe do not adopt the earlier name Gaidropsarits of Raliuescpie, Because we find 
little evidence that the rough tigure of Romlelet, ou which Gaidropsurits musUdlaris 
Ratiuesque was founded, was iuteiided for a species of Onos rather than ot Digciif. 
Eiicludgopiis Bloch & Schneider is a heterogeneous group, iucludiug species ot Gadiis, 
of which genus it may be cousidered a syuouym.
