kar’s note concerning the specimens is as follows :—‘‘ Oligochaete

found this worm. In other cases however it was found in the 
membrane surrounding the young snail.’’ 
Fic. 4.—Limnodrilus socialis; cerebral ganglion, from above. d.v., dorsal vessel. 
The tube contained six specimens, of which one was very 
small, in a good state of preservation. 
External characters. —The length was about 4 mm., the colour 
brownish; number of segments 31. The prostomium was short 
and bluntly conical; there was a head-pore between prostomium 
and first segment. ‘The clitellum embraced segments xii—xiii ; it

face of these segments. 
The setae are of the type which is ordinarily found in the

out nodulus, gently swollen towards the free extremity, and 
pointed at the end. Inlength they are approximately 50+. The
