Observation. As pointed out by Whiteaves (Pal. Fossils, Geol. Surv. Canada, 

 3, pt. 2, 1895, p. 102), Gomphoceras inflatum, the genotype of Septameroceras, is 

 a manuscript name of Billings applied to a rough cast of the body chamber of 

 a shell from the Silurian at L'Anse a la Barbe, near Port Daniel, Canada, with the 

 aperture badly preserved. He remarks further that this shell is probably the 

 same as Gomphoceras subgracilis or G. septore. As the latter is the best 

 known species of this type of structure, it would be well to recognize it as the 

 genotype of Septameroceras.
