Type Species
Enteroctopus membranaceus has often been regarded as type species of the genus, not because it was designated as such by Rochebrune and Mabille when they erected the genus, but because it was the first named species in the genus. Robson in his 1929 monograph of octopods regarded E. membranaceus as a species dubium because the original description was insufficient to identify an individual species, the holotype was an immature specimen, and the type specimen was no longer extant. As such, the genus was considered invalid until Hochberg resurrected it in 1998. Hochberg noted that Robson had considered E. membranaceus a junior synonym of E. megalocyathus, the second species assigned to the genus by Rochebrune and Mabille in their 1889 description. Additionally, since Rochebrune and Mabille did not actually assign type status to E. membranaceus, Hochberg concluded that Enteroctopus was indeed a valid genus and transferred type species status to E. megalocyathus by virtual monotypy.

Famous quotes containing the words type and/or species:
“It took six weeks of debate in the Senate to get the Arms Embargo Law repealed—and we face other delays during the present session because most of the Members of the Congress are thinking in terms of next Autumn’s election. However, that is one of the prices that we who live in democracies have to pay. It is, however, worth paying, if all of us can avoid the type of government under which the unfortunate population of Germany and Russia must exist.”
—Franklin D. Roosevelt (1882–1945)
“The French manner of hunting is gentlemanlike; ours is only for bumpkins and bodies. The poor beasts here are pursued and run down by much greater beasts than themselves; and the true British fox-hunter is most undoubtedly a species appropriated and peculiar to this country, which no other part of the globe produces.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
