. ? EMPTY PARTLY EMPTY FULL VII MONTHS Text-fig. 63. Paramolgula gregaria Traustedt. State of the gonad in all specimens, in all years, in relation to the month of the year. These groupings refer to the ovary; ' spawning' means that an appreciable quantity of eggs has been shed from the ovary and the specimen has evidently been taken during its female-spawning period. Animals under about 3 cm. have not been included as they had not yet attained sexual maturity. Text-fig. 63 shows the reproductive state of all animals over 3 cm. long. It seems that most of the spawning takes place in the months

These groupings refer to the ovary; ' spawning' means that an appreciable quantity of eggs has been shed from the ovary and the specimen has evidently been taken during its female-spawning period. Animals under about 3 cm. have not been included as they had not yet attained sexual maturity. Text-fig. 63 shows the reproductive state of all animals over 3 cm. long. It seems that most of the spawning takes place in the months of February to May, that the animals are spent during the southern winter, and that the gonad becomes active again in November. No material was available from the months of August and September. (b) Food. Specimens were examined from material collected at different times of the year. In all of these there was food in the gut, and at all seasons the food consisted largely of unicellular planktonic algae, mainly under 20 fi in diameter. Diatoms were also present, but less abundant. Occasionally parts of Crustacea (amphipods and copepods) were found, and it seemed that these were either alive or
