The Rev. F. H. Woods writes that the conditions of tide and 

 weather were not favourable for investigations of marine con- 

 chology. Nevertheless, the results were by no means without 

 interest, and in most cases the specimens found were those of 

 the living animals. In the roots of the larger seaweeds washed 

 up were some good specimens of the so-called var. IcBvis of 

 Helcion pellucida, which should rather be described as a state 

 than a variety, the peculiar shape which the shell acquires 

 being due to the hollow cavity which it makes for itself in feed- 

 ing. The upper pools abounded in Chiton cinereus. One 

 specimen of Chiton ruber, and one very large one of Acmcea 

 virginea were found. At low tide there were a few specimens 

 of Acmcea testudinalis, and great numbers of the tiny little 

 bivalve Turtonia minuta among the roots of the smaller algae, 

 on which a quantity of the fry of Lacuna pallidula were feed- 

 ing. But the most interesting shells were two specimens of 

 what for the present I am disposed to regard^as Rissoa proxima. 

 The shell in question, which I have found occasionally at Scar- 

 borough and elsewhere, is like Rissoa vitrea in its cylindrical 

 shape and deep sutures, but has the striae of R. striata. It 

 is possible that it may prove to be the var. arctica of the latter,
