196 DESCRIPTION OF PERIPATUS OVIPARUS, 
Peripatus oviparus, n.sp. 
Peripatus huckartii (probably in all cases where this name has 
hitherto been applied to specimens from Victoria with fifteen 
pairs of claw-bearing legs, especially in earlier papers of the 
present writer, but not where the name has been applied to 
specimens from New South Wales). 
A good-sized female specimen, when crawling, measured 39 mm. 
in length, exclusive of the antennae. Full-grown females preserved 
in spirit and contracted in the usual manner (not extended by 
drowning) measure about 20 mm. in length (exclusive of the 
antennae) by 4*5 mm. in greatest breadth (exclusive of the legs). 
The males seem to be commonly somewhat smaller than the adult 
females, but the evidence at present forthcoming is not sufficient 
to justify a generalization on this point. 
There are fifteen pairs of claw-bearing legs. Each leg has three 
pale-coloured spinous pads on its ventral surface. On the fourth 
and fifth legs the proximal and largest pad is divided transversely 
into three parts, the median part being much the smallest and 
bearing a white papilla. Each foot bears three large primary 
papillae, one anterior, one posterior, and one dorsal, overhanging 
the pair of claws. 
The jaws consist as usual each of two blades, the inner blade 
has about seven teeth and the outer one consists of a single well- 
developed tooth with a very small accessory tooth at its base. 
The integument is as usual transversely furrowed, with rows of 
papillae of varying size on the intervening ridges. Along the 
mid-dorsal line there is a deep narrow groove; the integument 
lining the floor of this groove is devoid of pigment and thus gives 
rise to a very narrow median white line, which may be hidden by 
contraction. 
The predominant colours of the skin are red and indigo blue, 
the former passing into yellow and the latter into black in some 
specimens. The characteristic pattern of the dorsal surface 
consists chiefly in a series of segmentally arranged, diamond- 
shaped patches in which the red colour is predominant. Each
