- f1 1393.f1Harris had lent CD several fossil cirripedes (see Correspondence vol. 4, letter to William Harris, 6 August ).
- f2 1393.f2Scalpellum tuberculatum and Pollicipes semilatus (Fossil Cirripedia (1851): 43, 72).
- f3 1393.f3Even the valves from the two species identified and named by CD were minute: he recorded that in Harris's specimens of S. tuberculatum the carina measured only 0.2 inches and the terga less than 0.15 inches (Fossil Cirripedia (1851): 43).
