218 PARAPERIPATUS LORENTZI. 
The genital aperture, lying immediately behind the last 
pair of legs, is rather indistinct in the female; in the male 
it is situated on an elongated backwardly directed conical 
papilla '). 
No doubt this species must be ranged among the genus 
Paraperipatus Willey *), as proved: (1) by the situation of 
the genital aperture behind the last pair of legs, (2) by the 
position of the renal papillae of the 4th and 5th leg in 
the middle of the proximal of the three pads, and (3) by 
the presence of three primary papillae on the feet. I think 
that Perip. ceramensis Muir a. Kersh. *) too belongs to this 
genus, though unfortunately we don’t know the male 
of this species. According to Muir and Kershaw »the 
bilobate ovarian chamber with the single duct leading 
from it’? should place it quite apart; however I cannot 
understand the meaning of this, for though the ovaries of 
Perip. novae-brittaniae are tubular, their cavities also unite 
into a common chamber, before communicating with the 
oviducts. Our specimens cannot be identified with either 
of the two named species, but must be considered to re- 
present a new species, the first one, as far as I know off, 
found in New Guinea; it thus fills up a gap in the hitherto 
known geographical distribution of these interesting ani- 
mals. Paraperip. Lorentzi may easily be distinguished from 
Paraperip. novae-brittaniae and — ceramensis, not only by 
its coloration, but also by the number of legs, 22 in the Q; 
in the penultimate species it amounts to 24 in the 9, whereas 
in the last species there are only 21 pairs of legs,
