Irregular Development in the Larval History of Meganyctiphanes norvegica

A new type of Nauplius belonging to Meganyctiphanes norvegica is described. Attention is drawn to irregularities in the development of the furcilia forms in which particular stages are sometimes omitted. It is suggested that in the larval history of M. norvegica in common with other Euphausids there...

Description
Summary:A new type of Nauplius belonging to Meganyctiphanes norvegica is described. Attention is drawn to irregularities in the development of the furcilia forms in which particular stages are sometimes omitted. It is suggested that in the larval history of M. norvegica in common with other Euphausids there is an indication of evolutionary progress in the group Euphausiaceæ.
