comparison; or was it that the authors mentioned thought that in 
each case the number of claw-bearing legs was the same; or that 
they knew that the numbers were not identical but regarded the 
difference as not of specific importance 1 Moseley's remark penned 
in 1879, "In the Australian and New Zealand species the number 
of feet seems fixed " — would, under the circumstances mentioned, 
seem without force if the last condition held. 
On the re-discovery of the Australian Peripatus, first in 
Queensland (in 1886)- not improbably first in Tasmania, though 
no record of it was made at the time — then in Victoria (in 1888), 
and in the same year in New South Wales, and all the specimens 
met with for several years were found to have 15 pairs of walking 
legs, it was imagined that these were correctly identified as P. 
leuckarti in supposed agreement with the " funfzehn Paar Fuss- 
stumel " of Leuckart's abstract of Sanger's paper. In 1890 Dr. 
Dendy met with a Victorian Peripatus, with 14 pairs of walking 
legs, and without an accessory tooth at the base of the fang of 
the outer jaw blades; and this he quite justifiably considered to 
be sufficiently distinct to be regarded as a second Australian 
species, which he accordingly described as P. insignis. In 1892 
Prof. Spencer obtained similar examples in Tasmania. 
We may now turn to 
" Sanger 's original Diagnosis of Perijjatus Leuckartii." 
" Found in New Holland, north-west from Sydney. Fifteen 
pairs of legs, one pair without claws, fourteen with. This 
character also found in P. brevis, described by Blanchard. 21 mm. 
long. Sexual opening between the last pair of appendages, herein 
differing from P. Edwardsii and P. capensis. Colour very nearly 
black dorsally, greyish ventrally. Papilla distributed dorsally 
and ventrally : those on the ventral surface, however, are longer 
and stand outwards laterally. Between each pair of appendages is a 
light oval spot without papilla?; this spot corresponds with the 
dark pits in P. capensis, under which occur the glands already 
described. The papilla?, as in P. capensis, are either small and 
black or large and red, but there are more black than red. Along
