The list of the shell-bearing mollusca by Bean (died December 22, 

 1866) is wonderfully complete, but includes several importations 

 which I have omitted. In all instances marked "Scarborough 

 (Bean)," the coast of Yorkshire or the Dogger Bank may be meant, 

 no definite localities being given, and a similar latitude may be 

 assigned to Scarborough Museum specimens. I have also had notes 

 from the Rev. W. C. Hey, whose recent death is so much to be 

 deplored, and from Messrs. Harman and Gyngell, of Scarborough, 

 who have made notes of their observations for many years. In all 

 these cases I have given the name of the recorder. For all notes 

 without initials I am responsible. I liave spent considerable time in 

 examining shellsand from the shore at Scarborough, which I have 

 found productive in species, but not so in specimens except of the 

 commonest kinds, and I am indebted to Mr. J. R. le B. Tomlin for 

 examining and naming for me all the smaller and more critical species. 

 Without his assistance these notes would not have been compiled.
