On the spawning grounds, therefore, we must expect to find newly-spawned eggs in the majority; outside these localities, the later stages will predominate. The investigations in the gulf of St. Lawrence are, however, to a very great extent free from these sources of error. It will be seen from the table that the spawning was in full progress during the first cruise of the Princess in June, and that so few late stages were found, may be explained as due to the fact of the hauls in question being made comparatively early in the season. On the August cruise of the Princess, however, this objection is no longer valid; the number of ova has greatly decreased, the season being now-nearing its close, and a far greater quantity of eggs in the later stages might have been expected. 'On going through the tables for the cruises of the Princess it will further be noticed that the proportion between newly-spaAvned ova and those in the later stages is approximately the same at all stations, only exceptionally do we find the later stages in the majority. No single station is so rich in newly-spawned ova as to exert a dominant influence upon the result as a whole, and there is thus no reason to question the representative value of the material on this head. As regards the number of larvae, this will always be subject to considerable error, as the larvae are more or less endowed with power of motion, rendering capture more difficult, in addition to which, their age is often difficult to determine. Com- parison between ova and young will therefore be su
