The medusa fauna of the mid North Atlantic Ocean between 24° and 55°N along approximately 30°W is studied. Two Hydromedusae new to science, Oceania tydemani and Annatiara lempersi, are described. The differences in fauna south and north of 42°N, and faunal borders near 50°, 48°, 45°, 35°, 30°, and 34°-37° N are discussed. The vertical distribution and for some species the diurnal migration and subtropical submergence are recorded.

This paper represents the second and final part of a study of the depth distribution and diurnal migration of pelagic decapod crustaceans in an area of the eastern North Atlantic. Part I (Foxton, 1970) dealt with the Caridea; Part II now considers the Penaeidea. In the discussion the data as a whole are analysed and the resulting patterns of vertical distribution and migration discussed.

Diurnal Migration

1. Previous work on vertical distribution and diurnal migration is described.2. The diurnal migration of Calanus was studied on two occasions in Loch Fyne (January and July, 1932).3. Vertical hauls were taken every three hours with a closing net dividing the total depth into six sections.4. The results for each copepodite stage of Calanus are discussed, and January and July conditions are compared where possible.5. Ova and nauplii were observed to be most abundant in the top 30 metres.6. Copepodite Stages I, II, and III were most abundant above 30 metres and only the third copepodites showed any tendency to descend as the light increased.7. Stage IV showed a migration towards the surface at night, but were generally distributed during the next day.8. It is suggested that the results for this stage are probably confused owing to its transitional nature between the young stages living at the surface and Stage V Calanus living in deep water.9. Stage V was found always in deep water, slight diurnal changes being ascribed to the presence of such Calanus as were about to moult into adults.10. Females showed definite diurnal migration in both January and July.11. Males showed a general distribution and migrated in small numbers towards the surface at night and away from it during daylight.12. Stage V copepodites and females both lived nearer the surface in January than in July, correlated with seasonal changes in the intensity of the sunlight.13. The presence of swarms of Calanus at the surface under conditions of bright sunlight is discussed.
