Note 69 — Chapter IV
Reading edition
Professor Huxley (Anat. Invert. Animals, p. 404) points out that the so-called pulvillus ought to be counted as a sixth joint. The same is true of the foot of Diptera and Hymenoptera, where there are six tarsal joints, the last carrying the claws. (Tuffen West on the Foot of the Fly. Linn. Trans., Vol. XXIII.)
