Themajority of the Onychophora are viviparous, and in such forms theembryos develop to maturity in uterine chambers of the oviducts (A,Utrs) ; with oviparous species the relatively large eggs are dischargedfrom the body before development begins. Development is alwaysdirect, and the newly born or newly hatched young have the form ofthe adult. Both male and female Onychophora have a single external genitalopening (fig. 6, Gpr), which is located near the posterior end of thebody, probably in all cases on the same body region, which is theventer of the p
