Type species: Gastrioceras compressum Hyatt, 1891, p.355 [OD].

[= Eoparalegoceras DELEPINE, 1939, p.34, type E. clariondi, p.34, M (subj.); for discussion see GORDON, 1965, p.263].

E:   Two grooves on venter may be present, constrictions common.
G:   Lobe of umbilical area centering at umbilical shoulder or on umbilical wall.

[Mapes et al., p.206: Pseudoparalegoceratid having umbilical lobe of suture located between umbilical seam and umbilical shoulder. Sutural formula = (V1V1)LU:ID.]

[Transitional to Pseudoparalegoceras. For discussion see Mc CALEB, 1968, p.55 and NASSICHUK, 1975, p.110].
 
[Nassichuk, 1975, p.110: The conch of Phaneroceras is discoidal at maturity and moderately evolute; typically the umbilicus approximates 40 per cent of the conch diameter. Shell sculpture includes lateral constrictions and sinuous growth lines that form a moderately deep ventral sinus and a relatively shallow lateral sinus. Faint longitudinal lirae occur in the umbilical region of some species. The suture has 8 lobes; prongs of the ventral lobe are slightly narrower than the first lateral lobe. The umbilcal lobe is situated either on the umbilical wall or on the umbilical shoulder].
