306 STUDIES ON AUSTRALIAN MOLLUSCA, XL, 



dredged by the Challenger Expedition in 25 fathoms, west of Cape 

 York. On comparing examples of these two in the British Museum, 

 I am unable to distinguish specific differences. 



Terebra flammea Lamarck. 



Terebra flammea Lamarck, Anim. s. vert., vii., 1822, p. 284; 

 Id., Reeve, Conch. Icon., xii., 1860, PI. iv., fig. 13; Id,, Reeve, Proc. 

 Zool. Soc, 1860, p. 450. 



Reeve has recorded T. flammea from Moreton Bay, Australia. 

 Material in the British Museum indicates that this species, and its 

 variety, T. incomparabilis Deshayes, inhabit the West Indies. The 

 Australian habitat is therefore a mistake. It does not appear to 

 have been remarked that Epitonium feldmanni Bolten, 1798, is an 

 earlier name for Lamarck's species. 



Duplicaria vallesia Hedley. 



Duplicaria vallesia Hedley, Rec. Austr. Mus., viii., 1912, p. 147, 

 PI. 43, fig. 31. 



This species closely resembles, but is specifically distinct from, 

 T. geminata Deshayes.* A Natal specimen, in the British Museum, 

 of T. geminata is more tapering, has a more twisted columella, and 

 its ribs continue on the base, whereas D. vallesia has a smooth base. 

 The median groove is a broader and deeper in geminata, and the 

 nodules above alternate with the ribs instead of continuing them, 

 as in vallesia. 



Duplicaria addita Deshayes. 



Terebra addita Deshayes, Proc. Zool. Soc, 1859, p. 293. 



This species was originally described from Tasmania, but, like 

 Terebra brevicula, it has been sought for in vain by local collectors. 

 The species is evidently foreign. One in the British Museum is 

 marked "type T. addita Desh., P.Z.S., 1859, p. 293, V. Diemen's 

 Land, M.C." This, I consider conspecific with three, perhaps type 

 but not so marked, labelled, "T. spectabilis Hinds, P.Z.S., 1843, p. 

 150 — Thesaurus, fig. 88 & 89. Guinea on the sands and Ceylon, 

 E. Layard, Esq. = gracilis, Gray."
