FEMALE ONCHOLAIMIUM. MONILIFORM GLANDS 



429 



various oncholaims I 

 have examined, except 

 minor ones in the more 

 or less, but very ob- 

 scurely, radiating part 

 that sets into the wall 

 of the intestine. This 

 part forms an "os- 

 motic" exit through the 

 the intestinal wall in 

 the shape of special, 

 presumably metabolic 

 and at least selective, 

 glandular tissue of the 

 osmosium. 



In the species Oncho- 

 laimus nigrocephalatus 

 there are external lat- 

 eral exit pores in the 

 anal region much as in 

 pristiurus but they are 

 minute. Thus far, how- 

 ever, I have searched in 

 vain for these pores in 

 Oncholaimium appen- 

 diculatum. 



In this latter species 

 there are two monili- 

 form subdorsal series of 

 24 cells each which I 

 propose to call monil- 

 iform glands. These 

 are rather close homo- 

 logues of the 64-fold rou- 

 leaux of zur Strassen; 

 less obviously, of the 8- 

 or 16-fold "Rothbraune 

 driisen" of deMan. The 

 uterine vessel joins the 

 right hand one of these 

 moniliforrn glands, as 

 is shown near the mid- 

 dle part of figure 3 

 on this page, at uv.
