Islands, which is a true Cochlostyla. Eeading Gillies's remarks 

 on B. antipodarum (Trans. N.Z. Inst., vol. i., p. 60) one gets 

 the impression that he mistook young specimens of P. hovinus 

 for Gray's species, and in this he was followed by others. 

 Professor Hutton kindly allowed me to examine specimens in 

 the Canterbury Museum, labelled P. antipodarum, and they 

 proved to be young specimens of P. hovinus, but were in no 

 way related to B. antipodarum. I am now of opinion that the 

 shell found by Dieffenbach, and described by Gray as B. anti- 

 podarum, has very likely never been found again in New 

 Zealand, and is in reality Cochlostyla fulgetrum, Broderip, 

 introduced accidentally from the Philippine Islands. This 

 suggestion is supported by the fact that Coclilostyla daplmis, 

 Broderip, from those islands, has been found at Picton 

 (Trans. N.Z. Inst., xxiv., p. 280). 



9. Amphidoxa and Flammulina. 



Albers founded the section Amphidoxa to receive two species 

 — A. marmorella, Pf., and A. helicophantoides, Pf., from Juan 

 Fernandez and Chili. Professor Hutton, in his Eevision of the 

 Land-shells of New Zealand, the foundation-stone of our present 

 knowledge of these molluscs, classed nine of our shells under 

 Amphidoxa, Albers, aiid gave descriptions and figures of the 

 dentition of eight of them. The diagnosis given by Albers, and 

 the figures of the species from Juan Fernandez, seem to fully 

 justify Professor Hutton's view in adopting Amphidoxa for our 

 shells, more especially for A. crehrlflammis, Pf., A. zebra. Lie 

 Guillou, and A. costulata, Hutton. Professor Hutton, and the 

 writer, never had an opportunity of comparing New Zealand 

 specimens with Amphidoxa specimens from Juan Fernandez, 

 and the dentition of the latter is still unknown. 



Last year Mr. H. A. Pilsbry published " Observations on 

 the Helices of New Zealand " (Nautilus, vi., Sept., 1892, 

 No. 5, p. 54, &c.), which, coming from such an able concho- 

 logist, were greatly appreciated by scientists in Australasia. 

 With regard to Amphidoxa, he says (I.e., p. 56), " The true 

 Amphidoxa has not been found elsewhere than upon the island 

 Juan Fernandez and the neighbouring South American coast. 

 I have compared specimens with the New Zealand shells, and 

 find that there is not the slightest ground for supposing them 

 congeneric." After such a verdict from a competent authority, 

 Mr. Hedley and the writer, in the " Eeference List of the 

 Land and Fresh- water Mollusca of New Zealand " (Proc. 

 Linn. Soc. N.S.W., vii., (2), p. 643), adopted the name Flam- 

 mulina, proposed by Von Martens (Critical List of New Zea- 

 land Moll., 1873, p. 12), for the New Zealand species for- 

 merly included in Amphidoxa, — F. zebra, Lie Guillou, being 

 the type.
