Sliell el()ngate-.sul)ulate, glos.sy, latlier tliin. Colour : a median 

 cream band between pale orange on the upper half of the wlioil 

 and on the base, six .summit whorls dark orange. Whorls 

 fourteen, including a two whorled tuibinate protoconch. 

 Sculpture : a deep furrow winds along the upper third of each 

 whorl. Straight rather oblique riblets, discontinuous froui whorl 

 to whorl, parted by wider interstices, about eighteen to a whorl, 

 are well developed at the suture, interrupted by and reform 

 below tlie sulcus, and fade at the periphery. Between the riVjs 

 appear under a lens a few faint spiral threads. Aj)erture small, 

 narrow, deeply notched anteriorly. Length, 27 ; breadth, 6 mm. 



On account of anatomical characters detailed by Troschel, Dr. 

 W. H. Dall ranked the species grouping round Buccitium 

 dnplicahim, Linne, as an independent genus of the Terebridae, 

 under the name of Duplicaria.'^^ This prin)itive group is well 

 developed in Australia. Among local species, D. nstvlata, 

 Deshayes, is comparable to the novelty in size and shape. It is 

 however more solid, of a uniform colour with finer and more 

 numerous ribs.
