Tapes geographicus and T. pullastra. — Mr. B. B. Woodward, in the last 

 number of the Journal, considers Gwyn Jeffreys " in error," in uniting these two 

 forms, and says " it would seem as though he had not looked up the authorities to 

 whom he refers," judging them only from a comparison of their shells. Mr. Wood- 

 ward, on the other hand, has looked up the authorities, but apparently ignored the 

 shells, and pronounces them "quite distinct." When he writes, however — "Both 

 T. pullastra and T. geographicus occur in the Mediterranean, a fact of which 

 Jeffreys, evidently from the wording of his remarks, was unaware "—he is mistaken. 



Gwyn Jeffreys says of T. pullastra — "Throughout the European seas 



T. geographicus is undoubtedly the same species" (Brit. Conch., vol. 5, p. 185). 

 And again, " Finmark to Alexandria and Mogador" {Proc. ZooLSoc, 1881, p. 717). 

 Those interested in the subject should refer to the latter paper. (See alsoy. Condi., 

 vol. 8, p. 27, 1895). T. pullastra has not a single specific character apart from 

 7\ geographicus, and its one varietal character is only superficial — that of the 

 geographical markings covering the posterior area only (as in some T. pullastra) 

 instead of the whole valve. It is true the Mediterranean form (geographicus) is 

 smaller, thinner, and more polished than the British one {pullastra), but those are 

 attributes common to all the Mediterranean Tapes. — J. T. Marshall. [Read before 

 the Society, December 12, 1900). 



Notes on Helicella Cantiana as food for the Turdidae. — I have already 

 drawn attention to the above mollusc being eaten by birds of the Thrush family 

 [Sci. Gossip, N.S., vol. 5, p. 366) at Reigate. During July last I was able to 

 extend these observations. On July nth I walked from Canterbury to Whitstable, 

 looking for flint implements in certain spots on the plateau. On the high road by 

 the side of the footpath I found the following specimens broken by birds : Two 

 broken Helicella cantiana and two H. nenioralis within a few feet of each other, the 

 H. cantiana together and the H. nenioralis together, three-quarters of a mile to the 

 north of Blean; and about a mile and a half further north, one H. cantiana and two 

 H. nenioralis (together) about six feet from each other, one of the latter was too 

 crushed besides, and too fragmentary to produce. The presence of the two different 

 species near each other shows that the birds are not driven to eat H. cantiana 

 through absence of H. nevioralis. — R. Ashington Bullen, F.L.S. {Read 

 befo7x the Society, November 14th, 1900).
