18. F. beddardi Bret. 1900, Bretscher, in Eev. Suisse Zool., 

 viii. p. 29; 1904, ibid., xii. p. 265; 1909, Southern, Proc. 

 Eoy. Ir. Acad., xxvii. p. 164. Newton Moss, near Penrith, 

 Cumberland ; collected March, kept alive and examined August 11, 

 1911. See F. ratzeli infra. 



19. F. bisetosa Lev. 1884, Levinsen, in Vid. Meddel. 1883, 

 Michaelsen, Das Tierreich, pp. 96-7. I have a large collection of 

 bisetose material which shows that. the group must be carefully 

 revised. Bretscher (1900, Bev. Suisse Zool., viii. p. 27) errone- 

 ously places here a form with four setse. I simply record the 

 species as British, and await an opportunity to sift and edit. 



19a. F. bretscheri Southern. 1907, Southern, in Irish Naturalist, 

 xvi. p. 73. 1909, Proc. Boy. Ir. Acad., xxvii. p. 160. Not to be 

 confused with F. parva Bret, or F. parva Moore. Dublin, Edin- 

 burgh, frequent in Notts and elsewhere, 1913. 



20. F. bulbifera sp. n. Supra, p. 141. To be compared with 

 bulbosa, glandifera, and others. 



21. F. bulbosa Bosa. 1887, Neoenchytrseus bulbosus Bosa, in 

 Boll. Mus. Torino, ii. No. 29, p. 2. Michaelsen, Das Tierreich, 

 p. 96, places F. parva Moore here. One of the most widely 

 distributed of British species. Already I have divided my mate- 

 rial and made two or three new species, but more remains to be 

 done. Friend, in J.K.MS., 1912, pp. 14-15. Trans. Notts Nat. 

 Soc, 1910-11, p. 40. 



22. F. callosa Eisen. 1878, Neoenchytrmus callosus Eisen in 

 Ofv. Ah. Forh., xxxv. No. 3, p. 76. Michaelsen, Das Tierreich, 

 p. 99; Friend, in J.B.M.S., 1912, p. 19. In April 1913 I found 

 in the gardens at Blenheim Palace, along with specimens of F. 

 michaelseni and F. leydigi, a worm which approaches this species 

 most nearly, though there are differences between my own notes 

 and Eisen's description. Trans. Notts Nat. Soc, 1911-12, 

 p. 62. 



23. F. clara Friend. 1913, Friend, in J.R.M.S., p. 267. I 

 have nothing to add to the description and record there given. 



24. F. connata Bret. 1902, Bretscher, in Bev. Suisse Zool., 

 x. p. 20. 1907, Southern, in Irish Nat, xvi. p. 75. 1909, Proc. 

 Boy. Ir. Acad., xxvii. p. 161. 1912, Friend, in J.B.M.S., p. 17. 

 Belongs to the bisetose group, and often needs careful study to 

 distinguish it from diach/eta, bisetosa, and related forms. More 

 accurate diagnosis is needed in this large and interesting section, 

 in the light of my recent gleanings. Trans. Notts Nat. Soc, 

 1910-11, pp. 34, 40'; ib., 1911-12, p. 56. 



25. F. coronata sp. n. Supra, p. 141. A clearly-defined species. 

 1913, Blenheim Palace. 



26. F. densa Friend. 1912, Friend, in Trans. Notts Nat. Soc, 

 p. 61. Collected in Notts December 16, 1912, and stated in 

 a footnote to be possibly a variety only of F. michaelseni. But
