or so I thought, be the type. The place where I collected the T. pupa was on the 

 American side of the falls just below the suspension bridge (Niagara). 



In view of the above facts, there seems insufficient reason for re- 

 garding this form as entitled to a distinct systematic position. 



Subgenus ElSENiA Malm, 1877. 



The location of the spermathecal pores near the mid-dorsal line, 

 or at least dorsad of d, separates this subgenus from others except 

 Eiseniella; from which it is distinguished by the extent of the gizzard 

 and probably by the position of the oviducal pores, as stated in the 

 description of the subgenus Eiseniella. 



HELODRILUS (EISENIA) lONNBERGI (Michaelsen). 



Allolobophora lonnbergi Michaelsen , 1894: 179. 

 Eisenia Z6nn6eryi Michaelsen, 1900a: 475. 



Length, 9.6 cm. Somites, 138. Color of dorsal and lateral sur- 

 faces, brownish violet; the pigment lacking on the lateral surfaces 

 of 8-12. Prostomium, epilobic |. Setae, closely paired and orna- 

 mented; those of the ventral pairs on most cliteUar somites modified 

 into long slender sexual setae; anteriorly, dd is somewhat less than 

 \ of the circumference and posteriorly only f of it. Chtellum on 

 24-30. Tubercula pubertatis on 26-129. Fhst dorsal pore on 

 7/8. Spermiducal pores on 15 without definite glandular elevations 

 surrounding them; each is dorsal to l and at a distance equal to 

 about 2ab. Oviducal pores on 14, slightly dorsad of h. Sperma- 

 thecal pores on 8/9-10/11, close to the dorsal median fine and near 

 the dorsal pores. Septum 12/13, slightly; and septa 13/14 and 14/15, 

 somewhat more strongly thickened. Sperm sacs in 9, 11, and 12. 

 Spermathecae in 9, 10, and 11. 



H. lonnhergi has been reported from Georgia and North Carolina. 



HELODRILUS (EISENIA) CAROLINENSIS (Michaelsen) 



Eisenia carolinensis nomen nudum, Michaelsen, 1903: 137. 

 Helodrilus (Eisenia) carolinensis Uicuaelsen , 1910: 15. 



Length, 3.5 cm. Somites, 121. Color, more or less reddish, due 

 in part to weak red pigmentation of dorsal surface. Prostomium, 

 epilobic J. Setae, closely paired; posterior to the chtellum, aa: he: 

 dd = 4. : 3 : 6; anteriorly (M = i circumference. Chtellum on 24-31. 

 Tubercula pubertatis on 27-29, slightly dorsad of seta line h. Papil- 

 lae mclude ventral setae of 10, 16, 17, 24 or 25-31. First dorsal pore 

 on 5/6. Spermiducal pores on 15. Spermathecal pores in 9/10 and 

 10-11, close beside the mid-dorsal line. Septa of anterior somites 

 including the gizzard region are slightly thickened. Sperm sacs in 

 9, 11, and 12; those of 9 smaller than the others. Spermathecae in 

 10 and 11.
