DISTRIBUTION AND CLASSIFICATION OF ONYCHOPHORA. 397 
Peo On, Wie Par to 4. 15, Noe tyerand lei O£. these: the 
most important, and not found in any other group, are 7, 11, 
and 13 (the receptaculum seminis of P. cinctipes is so very 
small and simple that it hardly affects the point). But, 
although I assert the distinctness of the group, it must be 
confessed that it approaches Melano-Peripatus more closely, 
perhaps, than do any other two groups of species, not even ex- 
cepting Neo-Peripatus and Congo-Peripatus. This is es- 
pecially shown by the form of the jaws and the nature of the 
ovum, No. 11; through the species cinctipes in the arrange- 
ment of the distal pedal papille, No. 5; through the species 
Capensis in the absence of genital legs, No. 6; through the 
species Sedgwicki and Moseleyi in the tendency towards 
the presence of a trophic vesicle, No. 12; through most of 
the Cape species in the absence of well developed coxal organs, 
No. 17; and in the shortness of the unpaired part of the vas 
deferens. But the distinctness of Melano-Peripatus cannot 
be impugned, having regard to its characters 6, 7, 11, 12, 14, 
18; and 19. 
AUSTRO-PERIPATUS.—Peripatus is known from both 
Eastern and Western Australia, from Tasmania and from 
New Zealand. It is interesting to note that it has not so far 
been found in NewGuinea. All the species known, of which 
there are eight, belong to the group Austro-Peripatus 
(Peripatoides of recent authors). The characters are as 
follows: 
1. The number of legs (14 to 16 pairs) is constant in the 
same species. 
2. The outer jaw is either without minor teeth or with one 
or more minor teeth ; the inner jaw is without a diastema or 
a saw. 
3. The legs have three spinous pads. 
4, Nephridial openings of legs 4 and 5 on the proximal 
pad. 
5, Feet with three distal papilla (one anterior, one dorsal,
