86 THE ZOOLOGIST. 



as yet known in Great Britain. Rhynchelmis limosella, Hoffm., 

 which was found in Hants in 1913 is almost sure to occur, 

 and one or two species of Stylodrilus must also be indigenous. 

 Hitherto, however, only one genus, and but one species of that, 

 is on record. 



7. Lumbriculus variegatus (Miiller). — Michaelsen (9), p. 58. 

 First found by me in Pevensey Marsh in 1892. Taken in 

 Alexandra Park, Hastings, June 20th, 1912. Not uncommon 

 among water- weeds in streams and ponds or lakes. 



Enchytreidze. 

 Setae present, except in Achceta, straight, sigmoid, or bent 

 near the internal extremity. Girdle usually on segment 12; but 

 sometimes advanced three or four segments (as in Chamcsdrilus 

 and Buchholzia). Spermathecae opening between segments 4 

 and 5 ; either free within the ccelom or more frequently attached 

 to the intestine. Dorsal pores in one genus (Fridericia). Blood 

 usually red in the Pachydrylid section, otherwise colourless or 

 yellowish. A very large and interesting family, concerning 

 which I have written much during the past three years, especially 

 in the ' Journal of the Royal Microscopical Society ' and in these 

 pages (1). One new genus (Chamadrilus, Friend) is at present 

 known only in Britain, where, however, it is widely distributed. 

 To the genus Henlea, as well as to Fridericia, I have recently 

 added many new species. So far as our present knowledge goes, 

 England has more Encbytrseids than any other country. I give 

 the Henleas alphabetically. 



8. Henlea arenicola, Friend. — 1912 (6), p. 586. Found 

 at Bopeep, Hastings, December 21st, 1911, and first described 

 from the material there collected.
