620 ON SOME PAUROPODA FROM N. S. WALES, 



almost at the elaw of the tarsus. The sueceedins: legs have similar 

 hairs, and. hi addition, a hair like that of the tibia upon the meta- 

 tarsus. In the ninth leg. the metatarsal hair is present, and there 

 is a distinct indication of division on the inner side of the tarsus 

 at a little more than half its length. All the legs have biramous 

 hairs upon coxa and trochanter. In the first eight, one branch is 

 much reduced, with a very short cylindrical process articulated dis- 

 tally; the ninth having subeqnal branches. The anterior legs are 

 distinctly three-clawed, the median longest; posterior legs with the 

 anterior branch of the empodium apparently clawloss, and the pos- 

 terior claw almost as large as. the median. 



The sexes are equal in size. The length varies from 1-5 to 1-7 

 mm. in sexually mature individuals; the breadth averaging 0*4 

 mm. 



Loc. — Liudtield; Broken Bay. 



The form of the anal plate at once places this species in connec- 

 tion with three Chilian forms described by Hansen, P. rohitsttts, P. 

 intermedins, and P. spectabilis; but it shows no very close relation 

 to any of these species. 



Paukopus austkalis, n.sp. (Plate Ixxi., tigs. 12-1 4). 



Of this smaller and more slender speciet^. 1 have taken about a 

 dozen specimens at Lindtield, where it is much less in evidence than 

 P. amicus, hiding between the laminae of barksheets. and only being 

 brought to light by careful searching. At Broken Bay. it was the 

 commonest species ; and I captured about twenty indi^•iduals under 

 stones in moist places. 



The form is slender, the sides subparallel, only slightly diverging 

 posteriorly. The cuticle shows a fairly long pubescence on the la^st 

 shield, anal segment, and posterior legs; a slight pubescence on 

 the fifth shield; and is smooth in front of that. The antenna has 

 the lower ramus a little more than half the upper, its flagella sub- 

 equal and symmetrically placed upon truncated angles on either 

 side of the globulus, which is large and distinctly stalked. The 

 upper ramus is distinctly narrower, and has its flagellum longer by 

 one-fourth than those of the lower ramus. The basal un-
