margin of the latter. The prostates extend through xvii-xxii. The 

 prostatic duct is 3-5 mm long, straight or bent into a C-shape, with a 

 tiny quirk just before passing into the parietes. 



The spermathecal duct is much shorter than the ampulla and nar- 

 rowed gradually in the parietes. The diverticulum, w'hich is about 

 equal to the combined lengths of the duct and ampulla or a trifle 

 shorter, passes into the duct in or close to the parietes and comprises 

 an ectal, slender, smooth-surfaced, firm stalk with a very narrow 

 lumen and a more irregular, thinner-walled seminal chamber with a 

 wider lumen. The elongate tubular seminal chamber may be 

 twisted, almost straight, or with one or two very slight loops ; it may 

 be of about the same caliber throughout or the entalmost portion may 

 be slightly widened. 



Numbers of stalked glandular masses protrude into the coelomio 

 cavity dorsal to each of the genital markings, the ducts passing into 

 the parietes under the nerve cord. In some of the specimens what 

 appears to be glandular material was fomid in the parietes around 

 the spermathecal duct. No glandular material was found in thq 

 parietes in the region of the prostatic duct in the specimens that 

 were carefully dissected. 



Remarks. — Two worms were found on dissection to have a small 

 spermatheca each in segment vii, with the duct passing into the 

 parietes in the region of 7/8, though no spermathecal pore had been 

 noted during the external examination. One of these spermathecae 

 lacks a diverticulum. The other spermatheca has a diverticulum but 

 with no spermatozoal iridescence, though seminal chambers of normal 

 spermathecae from the same worm do have the iridescence. 



P. anteflxa is distinguished from all other bithecal species of 

 Pheretima with spermathecal pores on 8/9 by the unpaired, presetal, 

 median genital markings and their anterior location.
