PARAPERIPATUS LORENTZI, 217 
NOTE XXV. 
PARAPERIPATUS LORENTZL HORST, 
A NEW PERIPATUS FROM DUTCH NEW GUINEA 
BY 
Dr. R. HORST. 
During his last expedition to the central mountain range 
of New Guinea, Mr. H. A. Lorentz collected a couple of 
Peripatus-specimens, which he kindly placed into my hands 
for examination. They were found amidst moss on Mount 
Wichmann at a height of 3000 M. That the couple con- 
sists of a male and a female may be considered as a 
happy chance, taking into account the rarity of the males 
in comparison with the females among the Peripatidae. 
The ground-colour of my animals is a uniform dark 
greenish-blue, somewhat paler on the ventralside especially 
on the legs, on each side of the segmentalgroove; moreover 
there is a median ventral row of small whitish spots. These 
spots, situated between each pair of legs, consist of a 
smaller, roundish, anterior one and a larger posterior one, 
somewhat sagittate. The papillae around the mouth and a 
ring around the middle of the oral papillae are whitish, 
whereas the pads of the legs are ochraceous, at least in 
the female; in the male the last coloration is less distinct. 
The female attains a much larger dimension than the 
male, the former measuring about 33 mm. in length, the 
latter only 19 mm. 
There are 22 pairs of legs in the Q, 21 in the o’. Each 
leg has three spiniferous pads, the middle one of which is 
the largest; moreover there are remnants of a fourth one. 
The renal papillae of the 4th and 5th legs are situated in 
the middle of the 3rd proximal pad. Each foot is provided 
with three primary papillae, one dorsal and two lateral, 
one on each side, 
The outer jaw-blade single, without accessory tooth.
