any diverticula. Its calibre is rather greater than is the case 

 with PolytoreuttLS kenyaensis and P. tnontis-kenyce. Anteriorly 

 the two oviducts enter it, and they are readily distinguishable 

 from the pouch by their nacreous, indeed almost bronzy glitter, 

 dvie, of course, to the thick muscular wall. 



It may be convenient to embody the above-given descriptions 

 in a short diagnosis of each of the new species of Polytoreutus 

 dealt with in the present communication. 



(1) Polytoreutus kenyaensis, n. sp. 



Length 100 mm. ; diameter 5 mm. Colour (in alcohol) purplish 

 brown above. Prostomium epicheilous. Clitellum (xiii.) xiv.- 

 xviii. Male pore xvii. ; female pore xviii./xtx. Genital area 

 formed by two curved ridges meeting anteriorly on xvi. and 

 posterioi'ly on xxiii.-xxvi. Sperm-sacs nari-ow and tubular ante- 

 riorly, wide and sacculated posterioi'ly, fused at extremity. Bui'sa 

 propulsoria veiy large ; sj)ermiducal glands without duct. Sper- 

 mathecal sac without diverticula ; oviduct with sperm-holding 

 diverticula ; no bursa copulatrix.
