(1)A Record of the Teleostean Eggs and Larvm observed at Plymouth in 1897. By. Ernest W. L. Holt and S. D. Scott, B.A. Abbreviations employed: sev. = several; m. = many; v.m. = very many; a.g. = oil globule. For convenience of tabulation the different stages of development have been divided into three gronps: Stage I. = if fertiJised, stages up to tne outgrowthof the eyes; II. from I. up to the appearance of the caudal rudiment; III. = from II. up to hatching. Since the ova were not always examined immediately after their capture, it has been necessary in many cases to compute the stage exhibited at that time. The divisions indicated above being fairly broad, the results set forth below are probably near the mark. Confusion is most liable to have occurred between Stages II. and III. All dimensions are given in mi11imetres.. =. Date.. Locality.. EGGS.. Position of Net.. No. I. Jan.
