AUT. 13 PARASITIC NEMATODES FROM CHINA SCHWARTZ 3 



Male. — The male is slightly over 10 mm long by about oii()/.t in 

 maximum ^v^dth, The spicules are filiform, equal, from 1.17 to 1.2 

 mm. long, and terminate in more or less sharp points (fig. I). The 

 gubernaculum is approximately 150^t long. There arc 10 pairs of 

 caudal papillae (fig. 1) of which five are pro and five ])ost-anal. Of 

 the former, the third is ventral in position, the remaining papillae 

 having a lateral direction. The first and second papillae are isolated, 

 the former being in the region of the sucker and the latter some dis- 

 tance from it. The three remaining preanal papillae are fairly close 

 together. Of the postanal papillae, the last aj^pears to have a ventral 

 direction (fig. 2) whereas the first four are lateral. The first papilla 

 in this group is very close to the anus. The longitudinal diameter of 

 the sucker varies from 145 to ISO/u. The tail ends in a slender tip.

Female. — The females are from 12 to 14.7 mm. long by 450/i in 

 maximum width. The vulva is located in the second third of the 

 body dividing the latter into two parts whose proportions in two 

 specimens are approximately as 7 is to 8, and as 10 is to 13, respec- 

 tively. The vagina runs cephalad for a distance of 1.5 mm. and 

 then turns dorsad where it joins the uterus. The tail is from 630 to 

 700/x long and tapers gradually (fig. 3). The eggs are from 72 to 

 81/x long by 45 to 51ju wide.

IVo species of Suhulura, heretofore described arc; known to occm- 

 in the genus Scops, one species (Suhulura acutissima Molin) being 

 from Scops hrasUianus from Brazil, and the other species {Suhulura 

 similis Gendre) being from Scops leucotis from vVfrica. These two 

 species are incompletely described, and so far as can be judged from
