DESCRIPTIONS OF GENERA AND SPECIES 607 



Genus EMINOSCOLEX, MICHAELSEN. 



DEFINITION. Lateral setae more closely paired than ventral. Male pores between 

 XVI/XVII. Calciferous pouches in IX-XI, calciferous glands in XIII. Sperma- 

 thecal apparatus paired ; true spermatheca present surrounded by spermathecal 

 sac at end ; ovaries enclosed. No penial setae. 



This genus agrees with Eudrilus in having completely paired genitalia. The 

 female organs have been more completely described in Eminoscolex toreutus than in 

 E. viridescens. The following is a more detailed account of their structure in the 

 former species. The ovaries are attached to septum xii/xiii. Each is enclosed in a 

 sac which is continuous with a large spermathecal sac extending backwards ; near 

 to where the ovarial sac opens into the latter arises, on the one hand, a stalked 

 egg-sac, and on the other, the oviduct. Between segments xii/xiii opens on to the 

 exterior a sac, the posterior end of which appears to be enclosed by, though it 

 does not open into, the spermathecal sac. This is not, however, quite certain ; the 

 present genus may resemble in this particular Eudriloides or Hyperiodrilus. In 

 any case the genus is more closely allied to the latter, since it has the dilated 

 vesicles upon the sperm-ducts immediately after their origin from the funnels, and 

 has the unpaired calciferous glands so characteristic of the present subfamily of the 

 Eudrilidae.
