Euphausiacea

It was not possible to identify euphausid larvae without dissection, and the significance of this group in the harbour plankton did not warrant this detailed study. Several species first occur in September and are present through to December, but in these months they are few in number. They are common in January and February, but rare in March and April. Euphausid larvae are absent for the remainder of the year (Text-fig. 7). An euphausid larva, probably of the fifth "Furcilia" stage is illustrated in Text-fig. 4, A.
