The ppawniiifr in Canadian waters evidently extends over a very loniz jx-riod. On the first cruises of the Acadia and Princess, May 29 to June 16, free larvae of cod were found, while on the last cruises, July 21 to August 12, ova were still obtained in early stages. This is doubtless due to the extraordinary conditions of temi)erature in these waters. Of the Onus eggs and larva>, most no doubt, belong to 0. cimhrius, Plate III, figs. 21 to 22, but as pigmentation, especially of the larvae, varies somew^hat, I could not feel certain that all belonged to this species.
