The larvae of Pasiphaea multidentata (Esmark) and Pasiphaea tarda (Kröyer).

• Pasiphaeid larvae collected in the Korsfjord, western Norway, were found to split up into two groups. Mainly two characteristics separated the larvae viz. the size of the larvae and the number of telson spines. The group with small larvae (8 to 10 mm) and the larger number of telson spines is referred to Pasiphaea multidentata and that with large larvae (10 to 12 mm) and fewer telson spines to Pasiphaea tarda. Embryos ready to hatch from an ovigerous female of Pasiphaea multidentata were dissected and it is shown that they resemble the small larvae above.
