The degeneration of the spinous dorsal in Psychrolutes and Gil-bcrtidia of the North Pacific has been already noticed. Thesegenera seem to lead directly from Cottunculiis to Li pari s. Fossil Cottidw are few. Eocottns veronensis, from the Eoceneof Monte Bolca, is completely scaled, with the ventral rays i, is apparently related to Jordania, but is still more (aries and mmierous other species, mostly from theMiocene) is covered with scales, but apparently has fewer thanfive soft rays in the ventrals. Remains of Oncocottiis, Iccliis,and Cottiis are found in Arctic Pleistocene rocks. The familyas a whole is evidently of recent date. The Rhamphocotiidcc consist of a single little sculpin with alarge bony and singularly formed head, found on the PacificCoast from Sitka to Monterey. The species is called Rhampho-cottus richa
