Powell, AWB 1979, "New Zealand Mollusca", William Collins Publishers, Auckland

Having looked at Okutani 2000, I see Conradia (A Adams 1863) spp
there... which if I'm correct would appear to be congeneric with
Crosseola Iredale 1924, which would be the junior synonym.

I think I have to retract my statement that Fossaridae lack collabral
sculpture and possibly terminal varices. However I would like to see
a revision of the group and good evidence as to where it stands (ie
distinct family or a synonym of Skeneinae), and if distinct, whet
superfamily it belongs to. It may be that Fossarus, Conradia and
Crosseola are being confused or are synonymous. Dunno!
