Vertebrata 
Pholis gunnellus Linn. This little fish was common under stones between 
tide marks during low water. It also hunted in the pools below. The 
stomachs of three individuals examined June 23 contained: — 
(1) three amphipods, part of a small isopod, a small Littorina shell, 
(2) two Allorchestes littoralis, three barnacles {Balanus) , 
(3) three barnacles {Balanus) . 
Other larger fish were seen in the deeper water but none were captured 
or identified. 
Bufo sp.? Toad tadpoles were present in the pools on the rock beach 
above the barnacles at Station 6, where fresh water seeped out over the 
rocks. 
Actitis macularia (Linne) Naumann. A spotted Sandpiper’s nest in 
the grass above the rocks at Station 9 contained four eggs from June 23 
to June 27. Young sandpipers were running about on the beach on June 
25 at Station 8. 
Mus norvegicus Erxleben. At least two rats lived among the rocks 
at Station 9. They came out and fed in the Ascophyllum at low tide.
