provided with an elongate, more or le^s tingerlike, primary ampulla, 

 the base of which is sunk deeply into a cleft in the dorsal margin. 



The prostate ducts are 6-8 mm in length, muscular, but uniformly 

 slender throughout, i. e., without special thickening of an ectal 

 portion. 



The spermathecae are flattened out on the ventral parietes. The 

 duct is much shorter than the ampulla, almost triangular in out- 

 line. The diverticulum, which passes into the anterior face of the 

 duct just at or within the parietes, is a slender, elongate-tubular 

 structure. In an ectal stalk portion of the diverticulum (about 

 one-half or more of the length) the lumen is narrow; the wall of 

 the lumen smooth or ridged transversely. In the remaining ental 

 portion of the diverticulum the lumen gradually widens until the 

 wall becomes very thin. This ental portion is doubtless the seminal 

 chamber, but it is not noticeably wider than the stalk nor marked 

 off from the stalk. Within the seminal chamber is an elongate, 

 opaque, firm mass with no spermathecal iridescence, the mass com- 

 posed of corpuscular bodies and smaller, homogeneous, s]:)heroidal to 

 ovoidal particles. Several bodies, apparently nucleated, that may be 

 parasites were also noted. 



Dorsal to each genital marking a glandular mass projects through 

 the parietes and very slightly into the coelomic cavity, the gland- 

 ular material just median to the ectal end of the prostatic duct. 



Remark^.. — Michaelsen (1910, p. 107) referred to the holotype as 

 "ein vollstandiges geschlechtsreife Exemplar." The clitellar gland- 

 ularity is almost certainly not fully developed and this together with 

 the small quantities of testicular coagulum in the testis sacs indi- 

 cates that the worm is either not quite normal (also note sperm- 

 athecae) or not completely sexual (presexual or postsexual). 



Although the gut, septa, and attached organs of the anterior seg- 

 ments had been dissected from the worm, dissection and preserva- 

 tion were such that determination of the characteristics of the testis 

 sacs was not difficult.
