Shell attenuate, straightly and narrowly fusiform, solid, cinnamon- 

 brown or dark brown, whorls eight, two (?) being apical, the rest 

 slightly impressed suturally, compact, shining, irregularly and rather 

 incrassately longitudinally ribbed, crossed spirally with thickened, 

 coarse liras, the interstices slightly squamulate, lowest whorl pro- 

 longed, ribs evanescent below the middle to the base, aperture 

 narrowly oblong, outer lip thin, contracted suddenly towards the 

 base, the canal being somewhat prolonged, columellar margin almost 

 straight, obscurely and obliquely twice plicate. 



Long.: 25; diam.: 10 mm. 



Hah. : Dredged alive, St. Vincent's Gulf, South Australia (Matthews), 

 (Verco), Spencer Gulf, 13 fathoms (Verco), shell sand, Aldinga Bay 

 (Kimber), Encounter Bay (Adcock), Middleton, South Australia 

 (specimen in coll. Rev. Lewis J. Shackleford, from which the 

 above rough description was taken). 



I am indebted for the sight of this shell to the Rev. Lewis 

 Shackleford, and have no hesitation in pronouncing it a true Latirus, 

 the columellar plicge are distinct and oblique, and it belongs to the 

 same section of the genus as aureocmdus Sow., and angustus Smith. 



It seems to me that Latirofusus Cossmann, had best be retained 

 for fossil species only. I have not seen a recent form really adapted 

 to this genus.

The following is a translation from the Latin description :—- -Shell 

 pyramidato-fusiform, attenuate, rather solid, ash coloured, apex acute, 

 whorls seven to eight, longitudinally thickly ribbed, regularly and 

 uniformly spirally very closely rugoso-striate, aperture oblong, canal 

 produced at the base, recurved, columella hardly plaited. Inner lip 

 distinct and continuous. 

 Lofig. : 25 ; diam. : 8 mm. 

 LJab. : Cossack, West Australia (J. J. Walker). 

 Of this I only possess one co-type in my own collection, but it is 

 represented by the original type in the National collection, and I have
