 tellum, XXX-LI. Setae strictly paired. Tubercula puhertatis, a ridge on each side 

 occupying ten or thirteen segments. Spermathecae, seven pairs. Hab.— Italy ; S. France. 



The enormous size of this species distinguishes it from all other European species. 

 730 mm. is given as the extreme length of the species; the measurement in the definition 

 is taken from Vaillant.

p. 180. 

 Lumbricus terrestris, DugIis, Ann. Sci. Nat., (3) viii, 1837, p. 18.

 A. longa, Ude, Z. "wiss. ZooL, 1886, p. 136. 



Definition. Number of segments, 180. Clitellum, XXFI, XXFII-XXXF. Setae paired. 



Dorsal pores commence XII/XIII. Tubercula pubertatis on XXXII-XXXIF. Spermathecae, 



two pairs in IX, X, opening posteriorly in line with lateral setae. Hab. — Germany ; 



England. 



The colour of this species is described by Ude as being brownish dark-grey in 



front, paler behind. On segments ix-xi, the ventral setae are borne upon papillae. 



The size and general appearance are stated by Ude to be as in Lumbricus herculeus. 



The identity of A. longa with the previously described 'Enterion terrestre' is fully 



gone into by RosA (15, p. 49), who is of opinion (15, p. 77) that L. teres may also
