10. A. rosea, Savigny. 26–3229–31. Widely distributed. The fluid discharged on irritation leaves a white sediment behind, which seems to be a form of calcium, the study of which might throw some new light on the use of the calciferous glands.
11. A. chlorotica, Savigny. 29–3731:33:35. Very variable and ubiquitous. I place here for the present the worm I formerly described as A. cambrica. Until we know more of the limits and extent of variation, and can draw a firmer line between species and subspecies, form and variety, it is better not to multiply terms. Several subspecies and varieties have been named by Rosa, Ribaucourt, and others, and our British forms would well repay careful examination.
12. A. georgii, Michaelsen. 29-3531–33. Tubercula as in trapezoides, which it nearly approaches. I have received it from Clonmore, Co. Clare, Ireland, which is thus far its only decided British habitat.
13. A. fœtida, Savigny. 27–3228–30. The well-known Brandling of the angler; at once recognized in England by its characteristic colour-bands. On the Continent more than one closely-allied form occurs. The species which comes nearest to it in our British fauna is the next.
14. A. subrubicunda, Eisen. 26–3228–30. Appears to be generally distributed in the British Isles, and liable to great variation, the forms of which (and their causes) merit special investigation.
15. A. hibernica, Friend. 27–3330–31. Probably the same as A. veneta, Rosa. At present known from Dublin and Louth in Ireland, but not found in England. (Proc. Royal Irish Acad. 1893, p. 402.)
16. A. mammalis, Savigny. 30–3633–34. I have found this worm in many parts of the country, and recorded it under Rosa's name A. celtica.
17. A. arborea, Eisen. 27–3129–30. Should not be placed under subrubicunda, as it is at least a good subspecies. Collected in or received from different parts of England, Ireland, and Wales.
18. A. eiseni, Levinsen. 24–320. A pretty anomaly, owing to its having the cephalization of a true Lumbricus—a connecting link between the two genera.
19. A. boeckii, Eisen. 29–3331–33. Only two authentic records, earlier records belonging to subrubicunda. Apparently a boreal
