276 EKANK E. BBDDAED. 



ring of tubing derived from the coelomic species connected 

 with the egg-conducting apparatus. lu Paradrilus the 

 homologous pouches open into the interior of the gut. 

 The following may serve as a definition of the genus. 



Alvania, nov. gen. 



Setse paired, ventral setae separated by a wider 

 interval than dorsal. Clitellum 15 — 17; male pore 

 upon 17 — 18, connected by a groove with two penes 

 upon 14 or 15. Spermatothecal orifice upon 10. No 

 integumental sense-organs. Alimentary tract with 

 five gizzards beginning in 18; calciferous glands in 

 13; calciferous pouches in 9, 10^ 11. Ovaries en- 

 closed in separate sacs; ampullae of egg-conducting 

 apparatus communicating above gut, and connected 

 with a long spermatothecal sac; true spermatothecae 

 absent. Funnels of sperm-ducts depending from 

 anterior walls of Segments 11 and 12; sperm-ducts 

 therefore perforating these septa twice, dilated 

 before termination in funnels. Atria paired, but 

 opening by a common orifice. No penial setae. 



I do not propose to attempt a definition of the species.
