Pekissogaster Queenslandica, n.sp. 
Two spirit specimens 15-3 and 15’8cm. long respectively, 5-8 mm 
broad; number of segments about 220. 
Colour flesh-colour, but wdth a slight tinge of brown. Pro- 
stomium ribbed with from 3-5 vertical grooves ; does not divide 
the buccal ring, though the latter having its anterior half ribbed 
all round, it may accidentally appear to do so partially. 
SetcC of the outer couples further apart (on an average about 
twice the distance) than those of the inner ones, the outer row of 
each outer couple sKghtly sinuous. 
Clitellum : no sign of it in either specimen. 
Male pores corresponding with the interval between the sette of 
the inner couples of segments xviii — which are not visible on this 
segment, — or even a little closer to the median line, in one speci- 
men on slight papillae. Spermathecal pores two pairs, on the 
anterior margins of vin and ix, rather close together, and ventrad 
of the inner rows of setae. Accessory genital structures not 
developed. 
Xephridiopores not visible. Dorsal pores commence unusually 
far forward, the first one rudimentary, between segments ill and 
IV, the others very conspicuous, not circular but slit-like. 
Alimentary canal : three gizzards in segments v-vii ; dilatations 
of the canal in some of the segments xiv and xv, appear to be 
the only representatives of calciferous glands. 
Genitalia : two pairs of testes and ciliated rosettes in x and xi ; 
three pairs of vesicul* serainales in xi-xiii ; prostates in xviii, 
with very short genital ducts as in P. ejxavata ; penial setae were 
not met with. Spermathecae : two pairs in viii and ix, each with 
a rudimentary rosette-like caecum. [The small size of the 
vesiculae, prostates, tkc., together with the absence of the girdle, 
all tend to show the non-breeding condition of the single specimen 
dissected]. Last pair of heaits in xii.
