5. Feet with two distal papillae, one anterior, one posterior. 



6. Genital opening between the legs of the penultimate 



pair. 



7. Receptacula seminis present, with two ducts opening into 



the oviducts. 



8. Receptacula ovorum present 



9. Oviducts united fo: some distance in front of ovary, 



Qa. Ovaries completely fused, with a single cavity. They lie 

 closel}^ pressed against but not directly attached to 

 the floor of the pericardium, to which, however, they 

 are connected ]msteriorly by means of a funiculus. 



ID. The ovary is exogenous, i.e. it is studded with follicles 

 in which the maturing ova lie. 



ir, The ova are large and heavily charged with food-yolk; 

 they measure about i 5 mm. in their longest diameter. 



12. Embryo without a trophic vesicle. 



13. Uterine embryos of about the same age. 



14 Unpaired part of vas deferens of very great length. 



15 Spermatophores long, with horny coat and cap. 



16. Skin-pigment brown, disappearing in course of time in 



alcohol. 



17. Legs with well-developed coxal glands. 



18. A single crural gland in the male in each of the two 



pre-genital pairs of legs. 



19. The accessory glands of the male open separately on the 



ventral surface between the genital opening and the 

 anus. 



To these it must be added that there is no external trace of 

 eyes and that there is a patch of highly modified scales, probably 

 sensory in function, on the lower surface of each antenna. 



The absence of eyes and the curious modifications in the 

 antennae are doubtless to be regarded as evidence of specialization. 

 They are not shared by any other genus of Onychophora and 

 have consequently been omitted in the table below ' which is in- 

 tended to give a general idea of the manner in which the various 

 genera are related. 



1 In this table I have employed the division of species, based on geographical 

 distribution, advocated by Sedgwick {loc. cit.), following Bouvier's monograph in 

 the matter of nomenclature so far as it is consistent with Sedgwick's scheme. 

 I follow Sedgwick in placing Opisthopatus cinctipes, Purcell, in the S. African 

 group, the name Cliilioperipattis being available for the species which Bouvier 

 refers to as Opisthopatus blatnvillet. Sedgwick has already pointed out that 

 Ooperipatus, Dendy, here merged with Peripatoides, is, according to Bouvier's 

 own showing, a polyphyletic genus. Since Sedgwick's paper appeared a species 

 of Peripatus, P. ceraniensis, has been recorded from Ceram (Muirand Kershaw, 

 Quart. Journ. Microsc. Sci., LlII, p. 737, 1909). This form is unquestionably 

 to be referred to Paraperipatiis and two additional species, also belonging to the 

 same genus, have been described from New Guinea (Sedgwick, Nature, L.XXIII, 

 p. 369, 1910, and Horst, Notes Leyden Mus., XXX II, p. 217, 1910).
