Oceanography. GENERAL BIOLOGY 757 >e classified in three groups: (i) the large ones, (2) an inter- mediate group, and (3) the small ones or fry, and when fishing we will very seldom be un- 0 14" 13 12 10 certain as to which group we may refer the fishes captured. It is impossible to apply the rule to both sexes, but the males seem on the average to be somewhat smaller than the females, and also less numerous. Among the larger sizes of the blen- nies, the longest ones seem to be sparingly re- presented. Notwithstand- ing all my exertions in various localities, I have never been able at this time of the year (summer) to find blennies of less length than the ones re- corded under the head of fry, that is, about 3 to 4 inches. As the fry, when born, are actually ij inch long, I cannot doubt that the group of small blennies, which at this time of the year differ so considerably in size from the large ones, really are the fry of the year, which during the last six months have grown to this size, that is, have added a couple of inches to their length. It appears equally natural to consider the intermediate group of blennies, between 6 and 8 inches, as the fry of the previous year. The direct conse- quence is that all the large blennies between 10 and 12 inches are of an age exceeding one year and a half by one year at Fig. 553- -Petersen's Measurements of zoarces Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Murray, John, Sir, 1841-1914; Hjort, Johan, 1869-.
