NEW SPECIES OF OCNERODRILUS. 279 



Considering these differences, I propose to place Gor- 

 diodrilus in a family of its own, Gordiodrilidie, which 

 might be characterized as follows (the description being- 

 after Beddard) : 



GORDIODRILID^. 



Small slender terrestrial oligocha?tai, with paired seta" 

 of the usual lumbricid pattern. Clitellum includes the 

 male pore. Nephridia paired, after the first few sur- 

 rounded by peritoneal cells. No pharyngeal or salivary 

 glands. Large septal glands investing the oesophagus in 

 somites v to vii. No typhlosole. (Esophagus with a 

 single median ventral divertieu/inn. No subnervian 

 vessel. Two pairs of hearts in x and xi. Testes in x 

 (andxi). Prostates opening indepoidently of the sperm 

 duets. Spermiducal pore in xviii. Ovaries in xiii. Ovi 

 ducal pore in xiv. Spermathecse variable, in vii or viii, 

 or absent, with no or rudimentary diverticula. No penial 

 setse, no subnervian vessel, and no blood vessels on the 

 nephridia. 



OCNERODRILID^.

 toneal cells, the posterior nephridia with more or less 

 peritoneal cells. Large pharyngeal or salivary glands. 

 Large septal glands investing the oesophagus in v to viii. 

 No typhlosole. (Esop/iagus with one pair of lateral 

 pouches or diverticula in somite ix, through which pass a 

 pair of large lateral vascular trunks. No subnervian ves- 

 sel. Two pair of hearts in x and xi (and sometimes a 

 third, smaller, in xi). Testes in x and xi. Sperm ducts 

 always opening in the same pore as a large prostate in xvii. 

 Sometimes an additional prostate opening independently
