a fully annotated Catalogue of the Land and Fresh-Water 

 Mollusca of the area, which would probably have been com- 

 pleted ere this but for the unsettled state of the nomen- 

 clature, and my desire to follow in this matter Mr J. Taylor's 

 grand monograph of the British species, now in course 

 of publication. My list contains 96 species, exclusive of 

 Neritina fiuviatilis and Paludina vivipara, which occur 

 only as ballast shells, and one or two doubtful records in 

 Captain Brown's "Illustrations" (1845), and some other 

 works. 



There are thus in all 339 species (with numerous varieties) 

 of Mollusca at present reported from " Forth." What work 

 there is still to do lies mainly among the marine forms, a 

 revised list of which is needed if only to incorporate the 

 records of the past twenty-five years, and modernise the 

 nomenclature. More observations, however, on many points 

 are required before a really satisfactory catalogue can be 

 drawn up. The l^udibranchs and Cephalopods, for instance, 

 want further investigating.^ From my own gleanings on the 

 sands of the Forth could be given additional records of a 

 number of our rarer shells. 



The subjoined is a list of recorded additions to Leslie and 

 Herdman's catalogue of the marine species. The names are 

 practically all left as they were published, but I have 

 ventured to place one or two in square brackets for the 

 present : there is always the possibility of " ballast " and 

 post-glacial shells to take into account. H. = Henderson, 

 P. = Pearcey, and S. = Scott.^ 



^ In dealing with the records of Cephalopoda in L. &H,'s list, the following 

 should also be consulted : — Loligo forlesii, Stp. (the so-called L. vulgaris of 

 our coasts), see Dr Hoyle's note in our Proceedings, viii. p. 459, and ef. also 

 Canon Norman's "Revision of Brit. Mollusca," Ann. and Mag. N. H. (6), v.; 

 Moschites {Eledone) cirrosa, T. Scott, Ann. S. N. E., 1893, p. 50, and paper 

 by me in same magazine for 1899, p. 6, on the destruction of animal life in 

 the Firth of Forth by the gale of Oct. 1898; Rossia macrosoma, W. Evans, 

 ib.; Sepiola rondeleti, R. Godfrey, A. S. N. H., 1900, p. 125. Pearcey's 

 record oi Octopus vulgaris {I.e., p. 238), if correct, is noteworthy; but prob- 

 ably Moschites is meant. 



Henderson's records are in his two papers in Proc. Roy. Phys. Soc, 

 viii.; Pearcey's in Trans. N. H. Soc. Glasg., n.s., vi. ; Scott's in Fishery 

 Board Reports {7th, 8th, 9th, 12th, and \Uh) except when otherwise stated. 

 Further records for many of the species in L. & H.'s list are also contained 

 in the papers of Scott and Pearcey.
