BB — IMetula long, strongly developed ; the lamina dorsales 

 with their posterior and caudad margin almost 

 evenly rounded throughout ; caput evenly rounded 

 caudad, half sphericle, the membranous space be- 

 tween the cephalad margin of the rostrum and the 

 caudad margin of the laminae dorsales narrow, 

 slitlike, the dorso-cephalad angle of the rostrum 

 and the dorso-caudad angle of the laminae dorsales 

 in one level ; peduculi penis distinctly longer than 

 the laminae dorsales. Gn. sulcatus Lee. 



The Female Reproductive Organs 



The female reproductive organs (fig. 33) were examined from 

 Gn. materianus Fitch only. As in all Rhychophora, two pairs of 



Fi<^'- 33- — Cnatlwtrichiis niatcriarius Fitch.: Female reproductive organs. 



A. the complete organs; B, receptaculum seminis; Ccg, cement glands; Or, ovaries: 

 0~'D, paired oviducts; Rec, receptaculum seminis; Te8, eight tergitcs, reduced; St>g, 

 spermathecal gland; Spr, spiculum ventrale; Var;. vagina. 



ovaries (Ov) are present which are connected distally. The paired 

 oviducts (OvD) are short and stout. The vagina (\"ag) is distinctly 

 shorter than the ovaries. Near the basal end of the latter two cement 

 glands (Ceg) originate. They are rather weakly developed, short 

 and ball-like in outline. A bursa copulatrix is not present. The re- 

 ceptaculum seminis (Rec) originates from the vagina at about the
