Note 49 — Chapter VII
Reading edition
Vide Huxley, “Craniofacial apparatus of Petromyzon.” Journ. of Anat. and Phys. Vol. X. 1876. Huxley’s views about the Meckelian arch, etc., are plausible, but it seems probable from Scott’s observations that true branchial bars are not developed in the Lamprey. How far this fact necessarily disproves Huxley’s views is still doubtful.
