MARINE BIOLOGICAL STATION ON PUFFIN ISLAND. 46 
Long before the time of Forbes, however, the two 
distinguished French naturalists Audouin and Milne- 
Edwards,* from their enthusiastic work as young men, 
among the rocks and islets of the Chausey Archipelago, 
and at other points along the coast of Normandy and 
Brittany, were able to distinguish five belts of life upon 
the shore:—(1) that of Balani (barnacles), only found on 
rocky coasts; (2) the zone of Fucoids, having limpets 
(Patella), whelks (Purpura, Nassa) and the common sea- 
anemone (Actinia) on rocks, sand-worms (Arenicola, 
Terebella) and sand-hoppers (Talitrus, Orchestia) on sandy 
shores, and certain other worms (Nephthys, Sipunculus) in 
mud; (8) the zone of ‘‘ Corallines,” only exposed at low 
tide, having mussels (Mytilus), simple and compound 
ascidians, crabs (Porcellana), Doris, worms (Serpula, 
Polynoé) and sponges in rocky places, the molluses Venus 
and Solen in sand, and the small Rissoa and Cerithiwm in 
mud; (4) the zone of Laminaria, having starfish, sea- 
anemones and the beautiful limpet Helcion pellucidum on 
rocks, and certain crustaceans on sandy ground; and (5) 
the lowest zone in which are found oysters (Ostrea), the 
sea-mouse (Aphrodite), the swimming crabs (Portunus) and 
the larger starfishes. 
The well-known Scandinavian zoologists M. Sars+ (in 
1835) and Sven Loven (more recently) directed their 
attention to the distribution of life around the Norwegian 
shores, and marked out four belts lying between high 
water mark and the Laminarian zone, viz:—(1) ‘‘ regio 
Balanorum,” (2) ‘regio Patellarum,” with Fucus vesicu- 
losus and F’. nodosus in its upper part, and F’. serratus and
