Foraminifera note details
p. 130: "We could have applied a special name to our examples from the Gulf of Gascony (e.g. Globigerina bulloides, var. rubra, subvar. pyramidalis); but this would give rise to a serious inconvenience: i.e. that the name rubra (typica) would remain applicable to the puny and poorly developed forms illustrated by d'Orbigny, whilst the true type, represented by specimens form the Gulf would be classified at a lower rank."
