The diameter of the lumen does not exceed one-fifth that of the 

 duct. Tbe glandless portion is short, and may be said to equal in 

 length the thickness of the girdle (fig. 6, p.p.) on the venter. 



One pair of testes is found in the tenth segment (fig. 2, t.) 

 attached to the posterior side of septum 9/10. In the same 

 segment, attached to the anterior portion of septum 10/11, is a pair 

 of funnels. Two pairs of sperm-sacs occupy the 10th and 11th 

 segments, but the anterior pair pushes forward (fig. 2, siJ.s.) into 

 segment 9. The position of the testes and sperm-sacs agrees with 

 that of the type.

The ovaries are seen (fig. 2, ov.) to be situated in segment 13, 

 and funnels or oviducts are attached to the anterior of septum 13/14, 

 while ovisacs are found in segment 14. In the type described by 

 Beddard no ovisacs occurred. 



The 7nale pores are on the ventral surface of segment 18, but 

 I have been unable to trace the duct from segment 10. The pores 

 do not lie in the same plane as those of the prostates. 



Kerria rubra possesses no peptonephridia, or salivary glands. 

 The ordinary uephridia commence in the 7th segment, and are 

 found in all the remaining segments except 11 and 14. In the
