in 110 fathoms, 34 good; in 150 fathoms, 10 good; in 200 

 fathoms, 2 good ; in 62 fathoms north-west of Cape Borda, 

 10 good and 4 immature. 



Mr. Hedley, to whom this species was submitted, writes: 

 — "Mr. May and I took this in 100 fathoms off Cape Pillar. 

 I catalogued it (Records Austr. Mus., vol. vii.. No. 2, 1908, 

 p. 112) as Drillia hasivelli, Hedley, but on reconsideration I 

 should regard it as new." It is narrower than D. haswelli, 

 its whorls are not angulated, the body- whorl is not so pyri- 

 form, and the spirals are much more valid. 



Var. crebrespirata, n. var. 



This shell is more solid and opaque, is 5'5 mm. long, 

 its body-whorl is 3 mm., its breadth is 21 mm. ; it has 15 

 spiral lirffi in the penultimate and 50 in the body-whorl, 

 crossed by crowded accremental striae. 



Two perfect individuals were taken in 49 fathoms off 

 Beachport. 



Var. sinusegfens, n. var. 



It is just like lacteoJa in size, shape, and sculpture, but 

 that the aperture is not pinched anteriorly to form a canal, 

 and there is no anterior sinus in the outer lip here. One 

 perfect example was taken in 100 fathoms off Beachport.

 Jackson Heads" ; Hedley, Records Austr. Mus., iv., 1891, p. 23,

This shell varies much in shape and sculpture. There 

 may be three sharp spirals on each of the four spire-wliorls 

 in a shell 8 mm. long, or two on the first and second spire- 

 whorls, an intercalated third thread on the third whorl, and 

 three on the fourth whorl. The shell may be shorter and 

 more solid, with two very strong spirals on all the spire- 

 whorls, and a weak intercalated thread on the fourth, with 

 about twenty obsolete axial lirse on the second and third 

 whorls, much less marked on the fourth. It may be short 

 and wide, with only two spirals in the spire-whorls, but in 

 the first and second, or first, second, and third whorls oblique 

 axial lirsB almost as valid as the spirals may cross and tuber- 

 culate these, and fade out in the later whorls. It may be 

 a long narrow shell, only 2"5 mm. broad, with four spirals 

 in each whorl, and with 16 oblique axial lirae like those in
