NOTES. 185 



The following specimens were exhibited : — 



By B. B. Woodward (on behalf of Raymond H. Chandler) : Holocene 

 shells from a pipe in the Chalk at Walton Heath. Some eighteen 

 species were shown, including the shells of Limax maximus and Vitrea 

 Soger si. 



By G. B. Pritchard : Older Tertiary shells from Victoria, comprising 

 examples of Cephalopods, Gastropods, and Pelecypods. 



By F. G. Bridgman : Varieties of Olivella oryza, Lamk. Attention 

 ■was particularly drawn to a small white variety (not figured by Duclos 

 or Eeeve) used by the natives of the West Indies in the construction 

 of shell-baskets. An exceedingly beautiful example of this work was 

 shown; also specimens of Olua intertincta, Cpr., 0. punctata, Marrat, 

 and 0. nitidida, Duclos. 



By E. R. Sykes : Types of shells lately described by him from the 

 Indo-Malayan region ; also a malformed specimen of the common 

 cockle ( Cardium edule). 



NOTES 



A Correction in Nomenclature. {Read 9th December, 1904.) — In 

 the ProG. Malac. Soc, vol. v, p. 345, a note was published by Messrs. 

 G. B. Sowerby & H. C. Fulton upon "a specimen of Flstulana clava, 

 Lamk., perforating a shell of Mitra interUrata, Reeve." This very 

 interesting object having been acquired by tlie British Museum, it became 

 necessary to prepare a label for exhibition, and it was found that neither 

 the name of the bivalve nor of the Mitra appeared to be quite correct, 

 but that they should respectively be Fistulana mumia (Spengler), and 

 Mitra circulata, Kiener, var. 



It is a most difficult and complicated que.stion as to which generic 

 name should be employed for the bivalve, but after considerable investi- 

 gation I am inclined to adopt Fistulana,'^ Bruguiere (1789), for this shell, 

 in agreement with Dr. Paul Fischer, who has discussed this point at some 

 length in the Journ. de Conch., lcS66, pp. 322-326. One important 

 reference he overlooked at the time, namely, Lamarck's " Prodrome d'une 

 nouvelle classification des Coquilles " in the Mem. Soc. Hist. nat. Paris, 

 an. vii (1799). On p. 90 he gave a brief diagnosis of Fistulana, and 

 quoted but one species, namely, F. clava. In this Prodrome, however, he 

 made no reference to Gastroch(xna or the species (cuneiformis. mytiloides, 

 and modiolina) which he subsequently, in 1818 (Anim. sans Vert., vol. v, 

 p. 447), placed in it. Fischer, iu his Man. de Conch., p. 1130, observes 

 that Lamarck limited Fistulana in an exact manner in 1799, showing that 

 he had subsequently referred to Lamarck's Prodrome, which appears to 

 have escaped his attention previously. With regard to the specific name, 

 that given by Spengler (mumia) has undoubted priority over Lamarck's 

 clava. 



Fistulana, Fabricius (1780), is evideutly merely a misprint of Fistidaria, Miiller 

 (1776).
