III. The Influence of Recent Gales on some Marine Forms of 

 Life. By Professor Du2sS, D.D. 



Shortly after the strong easterly gales that marked the 

 close of 1876 and the opening of 1877, I walked along the 

 shore from Leitli to Portobello, with the view of picking up 

 any of the less common marine forms that might have been 

 washed ashore in that locality. On many occasions I had 

 found that part of the coast very productive after a storm. 

 In the present instance, I was struck with the unwonted 

 numbers of some of the forms left a little below the high- 

 water mark. While moUusca prevailed, they were associated 

 with other classes, which told how very general the influence 

 of the storm had been. There were rays and fragments of 

 discs here and there of the common sand-star {Ophiura tex- 

 turata), the same in greater numbers of the lesser sand- 

 star (0. alhida), in greater numbers still the same of the 

 common brittle-star {Ophioeoma rosida), the arms of the com- 

 mon crossfish {Uraster rubeiis) and of the sun-star (Solaster ^mp- 

 posa), limbs of Crustacea — Carcinas, Lithodes, Galathea — and, 

 in pretty large numbers, dead hermit crabs (Pagurus Bcrn- 

 hardus) either in their naked condition, or connected with the 

 gasteropodous shells in which they had found a home. At 

 the high-Avater mark, on the shore near Leith, the connnon 

 sea-mouse (Aphrodita acideata) might have been picked up in 

 dozens. 



But I wish to refer chiefly to certain species of mollusca, 

 specimens of which are on the table in the condition in 

 which they were gathered, Looking at them from the point
