146 THE ZOOLOGIST. 



VIII. EOPHILA. 



No definite external characters to distinguish it from some 

 of the foregoing genera. I include here one species only, so far 

 as Britain is concerned. 



33-42 



30. Eophila icterica, Savigny. g. _^^ It will be seen that 



the girdle and tubercula cover a larger number of segments 

 than usual. 



IX. Helodrilus. 



Worms which live in mud, and are at present little known. 



31. Helodrilus oculatus, Hoflf. So far it has never been 

 found with a girdle, unless Michaelsen is correct in associating 

 it with the next, which I am at present unable to do. 



22 - 32 



32. H. hermanni, Michaelsen. ^^ _ g^ I place here also for 

 the present 



33. H. elongatus, Friend. Girdle extending from segment 

 15- 24. It may prove to be a Sparganophilus or a near ally. 



34. H. relichis, Southern. .. ~ ,,„ 



' 51-58 



The whole of the worms placed here under Helodrilus and 

 found in Great Britain are of peculiar interest, but need a great 

 deal of further investigation. 



X. Allueus. 

 The male pores are usually on segment 13, but may occur on 

 the 12th or 15th. They are small worms found in mud, and 

 have a square tail. Michaelsen has changed the name to 

 Eiseniella. 



35. Allurus tetrcedrus, Savigny. ^g_^g A well-marked golden 

 variety {luteus, Friend) is found, as well as the type. 



18-22 



36. A. tetragonurus, Friend. 



19-21 

 15-22 



37. A. macrurus, Friend. 



23 — 27 



38. A. hercynius, Mich. oo_oq Male pores on segment 15. 



20-21 

 i- 27 

 23-25 



Although this list still needs revision, it is the most complete 

 available at the present time. Some of the species are still 

 hardly known, and others are hard to define. We shall make it 

 the basis on which to found the notes which are to follow on the 

 distribution of Annelids as at present known in these islands. 



(To be continued.)
