tbe parts. Male pores on prominent papillge on segment 15, 

 Eeadily identified bj the backward position of the girdle, which 

 covers segments 34 to 39. Tuhercula puhertatis on 85, 36, 37, 

 38, forming a band along the clitellum omitting the first and last 

 segments. First dorsal pore between segments 5 and 6, thus 

 filling up a gap in the series as shown in the following table. 

 Copulatory setae on segments 29, 30, as well as on the under 

 surface of the clitellum. Spermatophores transparent sacs 

 attached to the ventral surface in front of the clitellum. 



Distribution, so far as at present known, Scotland to Grlouces- 

 tershire and Sussex ; at present peculiar to Great Britain, unless 

 L. festivus, Savigny, should prove to be the same. This worm 

 has, however, been observed by no recent investigator on the 

 Continent. 



3. LuMBiacus EUBELLUS, Hofmeister. 



Somewhat smaller than the foregoing. Usually about 3 inches 

 in length, purple, with brick-red clitellum, which is very promi- 

 nent in the adult worm, and extends from the 27th to the 32nd 

 segments. Eisen has rightly pointed out that occasionally the 

 girdle is shifted bodily one segment forward (26 to 31) , but this 

 is of rare occurrence in Great Britain. The male pores cannot 

 be detected on segment 15, even with a lens, but when the worm 

 is adult a band connects it with the girdle. The first dorsal pore 

 is between segments 7 and 8. 



It is widely distributed both at home and abroad, and has not 

 received so many aliases as most species have. It was first dis- 

 tinguished as a species by Hoff'meister in 1845. (Erley, owing to 

 his error in the identification of Lumbricus terrestris, L., revived 

 Savigny's name Enterion for this and the next species. Hoff"- 

 meister's designation, however, has undisputed right to be 

 retained. 



I have found this species at times with a very limited number 

 of post-clitellian segments, causing the worm to assume a very 

 characteristic appearance (var. curticaudatus, Friend) ; I have, 

 however, failed so far to determine whether the effect is due to 

 soil, height above sea-leveJ, want of proper food, or otherwise. 



4. Ltjmbkictjs puepureus, Eisen. (PI. XXI. fig. 11.) 



The smallest of our true Lumhrici, usually measuring about 

 2 inches in length. It is, however, very variable in size : some-
