One specimen introduced with plants into Hamburg from Fayette- 

 ville, North CaroKna. 



HELODRILUS (EISENIA) FOETIDUS (Savigny). 



Enterion fetidum {core . foetidum) Savigny, 1826: 182. 

 Allolobophora foetida Eisen, 1874: 50. 

 Eiseniafoetida Malm, 1877: 45. 

 Helodrilus (Eisenia) foetidus MiciiAEh8EN , 1910: 16. 



Length, 6-13 cm. Somites, 80-110. Color, conspicuous, due to 

 the transverse purple or brown bands on the middle of the somites 

 alternating with nearly pigmentless intersegmental areas; pigment 

 lacking on the lateral surfaces of 9-11. Prostomium, epilobic ^. 

 Setae closely paired. CUtellum on 24, 25, or 26-32. Tubercula puber- 

 tatis on 28-30 or 31. First dorsal pore on 4/5. Spermiducal pores 

 on 15, between h and c and not very near to either, Oviducal pores 

 on 14, slightly dorsad of h. Spermathecal pores on 9/10 and 10/11, 

 near the mid-dorsal line. Septa of anterior somites not much thick- 

 ened, those of 7/8-9/10, 13/14, and 14/15 most so but only very mod- 

 erately. Sperm sacs in 9-12, those of 9 and 10 smaller than the 

 others. Spermathecae more commonly in 9 and 10, but always in 

 close relation to the septa 9/10 and 10/11, and sometimes one or both 

 may lie posterior to them. 



H. foetidus finds very favorable conditions in manure and compost 

 heaps and is often found in decaying logs. It is abundant throughout 

 Europe and in various parts of the world where Europeans have 

 settled. In North America it is abundant and very widely dis- 

 tributed. It has been collected in most of the States where earth- 

 worms have been collected, including those of the Atlantic and 

 Pacific coasts, the Mississippi Valley, the Rocky Mountain region, 

 and the Gulf States. 



HELODRILUS (EISENIA) ROSEUS (Saviifny). 



Enterion roseumS AViGT^Y, 1826: 182. 

 Allolobophora rosea Rosa, 1893: 427. 

 Eisenia rosea MiCHAEhSEN, 1900a: 478. 

 Helodrilus (Eisenia) roseus Michaelsen, 1910: 14. 

 Allolobophora mucosa Eisen, 1874: 47. 



Length, 3-8 cm. Somites, 120-150. Color of living specimens, 

 pale red, but the body walls are without definite pigment. Pro- 

 stomium, epilobic J. Setae closely paired. Clitellum usually 

 includes 25-32 and occasionally involves 24 or 33. Tubercula 

 pubertatis, usually on 29-31, occasionally 30-31. Glandular papil- 

 lae often include one or more setal bundles of 9, 10, 12, or 13, which 

 may have modified genital setae. First dorsal pore on 4/5. Spermi- 

 ducal pores on 15 and nearer to h than to c. Oviducal pores on 

 14, just dorsad of h. Spermathecal pores on 9/10 and 10/11, close
