Drillia woodsi, Beddome, Proc. Roy. See, Tasmania, 1883 

 (1882), p. 167. Type locality — "Long Bay, D'Entrecasteaux Chan- 

 nel, Tasmania" ; Tate and May, Proc. Linn. Soc, New South 

 Wales, xxvi., 1901, part 3, p. 368; Hedley, Memoirs of Austr. 

 Mus., iv., part 6, 1903, p. 388, "New South Wales coast." 



Drillia h.owitti, Pritchard and Gatliff, Proc. Roy. Soc, Vic- 

 toria, vol. xii. (N.S.), 1899, p. 101, pi. viii., fig. 2. Type locality 

 — "Gippsland coast." 



Mr. Gatliff has kindly identified South Australian shells 

 as D. howitti; Tate and May, and Hedley, loc. cit., give 

 this as a synonym of D. woodsi, Bedd., and Mr. May says 

 ours are undoubtedly woodsi, from comparison with a draw- 

 ing he made from Beddome's type, and though I have not 

 seen this, on trust in their determination, I have called our 

 shell D, woodsi, Bedd. 



Taken on Middle ton Beach, solid and much rolled. 

 Dredged in 90 fathoms off Cape Jaffa, 1 good ; in 104 fathoms 

 off Neptune Islands, 1 good and 6 broken; in 110 fathoms 

 off Beachport, 2 good, 17 poor or broken; in 130 fathoms off 

 Cape Jaffa, 8 very poor ; in 200 fathoms off Beachport, 2 

 good, and 7 poor or immature; in 300 fathoms off Cape Jaffa, 

 1 poor. 



Var. acostata, n. var. 



This differs in having no axial costas, and in being less 

 solid. That it is only a variety appears from two facts — 

 first, the validity of the costse can be graded in a series of 

 examples from well-marked to absent ; second, some shells 

 have the costse valid in the earlier whorls, but they fade to 

 extinction in the later. It may reach a length of 21 '5 mm., 

 and have 12 whorls. Some individuals show 2, 3, or 4 opaque 

 • whitish hair lines in the substance of the spire-whorls. They 

 are frequently prettily coloured, pinkish-salmon, with three 

 rather indistinct bands in the body-whorl, a broad one be- 

 low the suture, not distinctly bounded inferiorly, a second 

 thin median band, and the third over the base and canal. 

 In the spire they form an infra-sutural and a supra-sutural 

 band. 



Dredged in 110 fathoms Beachport, 2 good, 3 poor, 5 

 immature ; in 130 fathoms off Cape Jaffa, 4 good, but imma- 

 ture ; in 150 fathoms off Beachport, 15 moderate and poor ; 

 iu 200 fathoms off Beachport, 17 good, 14 poor. They seem 

 to favour the deeper waters, and to be more numerous than 

 the typical forms there.
