10. A, rosea, Savigny. |=|j. 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. 31 S ^ 7 36 . Very variable and ubi- 

 quitous. 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. gjz^- Tubercula as in trape- 

 zoides, which it nearly approaches. I have received it from 

 Clonmore, Co. Clare, Ireland, which is thus far its only decided 

 British habitat. 



13. A. fcetida, Savigny. ^E§' 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. ^E§« 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, j^zjji* 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. §§r^. I have found this worm 

 in many parts of the country, and recorded it under Rosa's name 

 A. celtica. ■ 



17. A. arborea, Eisen. ^E^- 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. !L -^. A pretty anomaly, owing to 

 its having the cephalization of a true Lumbricus — a connectinj 

 link between the two genera. 



19. A. boeckii, Eisen. fjEJi- Only two authentic records, 

 earlier records belonging to subrubicunda. Apparently a borei
