pore sometimes present in the mid-dorsal area; in puntulifertis, in 

 addition to the clusters found in paradoxus, there are present large 

 pores in two rows of circularly arranged groups in the mid-dorsal 

 region and in transverse clusters before and behind the spiracular 

 groups. In addition, there are fewer pores in each of the spiracular 

 bands of quinquelocular disk pores.

There is in the Maskell collection a single slide of an adult female 

 in fair condition bearing No. 525. This number belongs to the species 

 hryoides stellata according to Maskeli's lot book, and supplementary 

 mounted specimens from unmounted material with the same lot- 

 number likewise agree with this mount. In addition, examples re- 

 ceived from Mr. W. W. Froggatt, collected at Mittagong, New South. 

 Wales, have been compared with the Maskell specimens, but are 

 considered to represent a distinct species. 



Adult female. — Test as described by Maskell; body as mounted 

 nearly circular in outline, excluding the protruding caudal apex of 

 the abdomen, total length around 2.2 mm., width around 1.8 mm.; 

 derm membranous ; antennae reduced to stout truncate unsegmented 

 cones, each slightly invaginated and bearing several stout setae at 

 apex; legs represented by flat conical plates, each with a distinctly 

 developed, slightly curved claw protruding from its center; beak 

 short conical, incompletely 2-segmented; marginal setae, as such, 

 apparently not definitely differentiated; no spiracular spines; dorsal 

 and ventral setae few, small and inconspicuous; 8-shaped pores 

 more or less definitely segregated ,into two size groups with the 

 long dimension of the larger as much as 22;*, and of the smaller as 

 much as 12//,, but both showing much variability, more even than in 

 hryoides, these pores intermingled and distributed over the dorsal 

 surface and margins of the body much as in hryoides, but with the 

 whorls decidedly less definitely developed; tubular ducts fairly nu- 

 merous and widely distributed, but small and inconspicuous, length 

 to cup about 21ju,; with bands of normally quinquelocular disk pores 

 running from spiracles to margin, these with the bands from each 

 posterior spiracle split and with the halves strongly diverging, often 

 with two (anterior) or one (each posterior half) tiny slender setae 

 at the outer end of the pore band, the numbers of pores in each ante- 

 rior band ai'ound 115, in each posterior compound band around 120; 

 ventral surface with a considerable number of small, scattered multi- 

 locular disk pores, often with obscurely bilocular center and usually
