6. Genital opening subterminal behind the legs of the last 
pair. . 
7. Oviduct with a receptaculum seminis with two ducts. 
8. Receptacula ovorum absent. 
9. The oviducts are united at the ovary. 
10. The ovary is exogenous. 
11. Ova of medium size (‘1 mm. in longest diameter) with 
little yolk. 
Fic. 9.—Dorsal views of feet of P. nove-britannia, showing 
the primary papille. In @ the dorsal papilla is inclined to the 
anterior papilla; in 6 it is median. (After Willey.) 
12. Embryo in its young stages provided with a large 
dorsal appendage, consisting of ectoderm and endoderm, 
and called by Willey the trophic vesicle. 
13. Uterine embryos of all ages in the same uterus. 
14. Unpaired part of vas deferens, very short, almost 
obsolete. 
15. Spermatophores absent. 
16. Skin-pigment black, apparently not affected by spirit. 
17. Legs without well-developed coxal organs. 
18. Crural glands absent. 
19. Accessory glands of the male open medianly and dor- 
sally near the hind one. 
This species, which we should expect from its locality to 
resemble Austro-Peripatus, presents seven peculiar fea- 
tures, 6, 11, 12, 14, 15, 19, of which 6, 11, 14, and 19 are 
important morphologically. By having a receptaculum 
seminis with two ducts and no receptacula ovorum it pre- 
sents a combination of characters found elsewhere only in
