SOME EAST SUSSEX OLIGOCHMTS. 85 



2. L. udekemianus, Clap. — Michaelsen (9), p. 45. Alexandra 

 Park, Hastings, June, 1912, and elsewhere. First collected for 

 certain at Amberstone Grange, August 30th, and at Battle and 

 Sedlescombe, August 31st, 1911. 



3. L.papillosus, Friend.— 1912, Friend (6), pp. 276-7. "First 

 found at Kew, August, 1911, and since discovered in gleanings 

 from the neighbourhood of Battle and Hurstmonceaux, Sussex." 

 Hastings, June 20th, 1912. 



4. L. aurantiacus, Friend. — 1911, Friend (8), p. 414. "My 

 notes show that this species is widely distributed in the South 

 of England, from Derbyshire to Kew and Sussex." Friend (6), 

 p. 275. 



5. Ilyodrilus meganymphus, Friend. — 1912, Friend (6), p. 289. 

 Described from specimens found in runnel in Alexandra Park, 

 below the Bohemia entrance. Found December 21st, 1911. 



Other species of Ilyodrilus occur in Sussex, but the Tubificidce 

 of Great Britain are under careful revision, and until my work 

 is somewhat more advanced, it would only result in confusion to 

 give further records here. 



6. Tubifex tubifex (Muller). — Michaelsen (9), p. 48. Friend 

 (6), pp. 291-2. Tubifex is common in Sussex as in most parts 

 of England, but hitherto several different species, and even 

 genera, have been confused under this name. I have taken 

 different forms in Alexandra Park, at Battle, Dallington, Hurst- 

 monceaux, and elsewhere. The same observation is true of 

 Tubifex which is made of Ilyodrilus. I have notes made many 

 years ago which suggest that Psammoryctes was at least once 

 collected by me in Sussex. The muddy banks of rivers, as at 

 Shoreham, would be prolific hunting-grounds, but have never yet 

 been worked. Heterochceta costata, Clap., and other vei'3 7 inter- 

 esting Annelids are sure to abound there, as they do in similar 

 localities on the Thames estuary. 



6a. T. heuscheri, Bret. — Near Kite's Nest, Hastings, June, 

 1912; only British record. 



Lumbeiculid^;. 

 Sigmoid setas either forked or pointed, four pairs on each 

 segment. Girdle in a very advanced position (segments 3-7). 

 Ten or a dozen known genera, of which only about one half are
