The shells of this genus differ from those of Pareuthria in having more obvious sculpture, composed of equally well-developed spiral and axial ribs. Thiele (1929, pp. 311-18) associated Glypteuthria and Probuccinum, but disassociated them from Pareuthria, which he made a subgenus of Northia. I cannot understand Thiele's action in doing this, for there is no evidence against the view that Glypteuthria is a strongly sculptured relative of Pareuthria, apart from the fact that the lateral teeth in Glypteuthria are not strictly bicuspid. In Pareuthria the laterals are bicuspid, but in Glypteuthria meridionalis bifurcation of the inner cusp results in a third incipient cusp, but this condition is not comparable with that of Probuccinum, in which there are three strongly developed and evenly spaced cusps.
The distribution of Glypteuthria, previously considered Magellanic, is now known to extend to South African waters, i.e. capensis (Thiele, 1925, p. 179) capensis* and solidissima (Tomlin, 1932, pp. 164-7). The Magellan species are meridionalis Smith, 1881, kobelti Strebel, 1905, and acuminata Smith, 1915.
