Sagittal section through the 

 ovarian region of a female Car- 

 cinonemertes wickhami. The ova-

 they are actually in two (only one 

 side of worm in figure; compare 

 with Figure 1); lateral nerve (N); 

 submuscular glands (G). Bar =

variable in size in relation to developing ova, 196-294 

 long by 92-168 in diameter. Eggs faint pink, deposited 

 in a flimsy, mucous matrix (cf. sac) secreted by female. 



Male (3 living specimens, incomplete observations on 

 2 additional specimens) Similar in gross morphology 



to female; differences include: diameter of worm ex-

 off the anterior portion of the worm as a relatively 

 slender head (cf. shoulder). Color pinkish white. En- 

 sheathed with female or free in egg mass. Length 5-18
