Localities .— 
Macquarie Island. 
Commonwealth Bay, Boat Harbour— 
Station B, 25 fathoms (forty). 
Station 3, 157 fathoms (three). 
Station 7, 60 fathoms (eight). 
Station 8,120 fathoms (nine). 
Station 12, 110 fathoms (seven).

Baird established his species on a single specimen obtained dining the Ross 
Antarctic Expedition; it was without a tube, and was characterised by its operculum. 
McIntosh (1876, p. 322) compared it with a specimen collected by the Venus Transit 
Expedition to Kerguelen, which, although it lacked the operculum, was in its tube. 
He satisfied himself that the two are identical. 
In 1897 Ehlers placed Band’s species as a synonym for S. vermicularis , and 
suggested that McIntosh’s var. margellanica should be included. But in 1912 Ehlers 
makes it a distinct variety, the tubes of which, he showed, are linked on with the type 
by a number of intermediate forms, in some of which even the everted lip, upon the 
possession of which Baird founded his species, was lacking.
