624 ON SOME PAUROPODA FROM N. S. WALES, 



but differ in details. The dorsal setae have the same peculiar 

 arrangement and proportions, except that the submedian pair is 

 at least as long as the lateral. The styli differ in being more 

 curved in over the anal plate, and in having broadly spatulate 

 ends. The posterior ventral setae are situated upon protuberances, 

 which are rather more oblong in shape than those of P. morten- 

 senii, and the seta3 themselves are not much more than one-half the 

 length of the submedian dorsal setae, and are a little swollen, not 

 tapering, distally. The anal plate is generally like that of P. mor- 

 tensenii, but the two processes are deeply incised on their inner 

 margins a little behind tlie apices; and, behind these clefts, are a 

 pair of rounded, rudimentary processes, a little dorsal to the plane 

 of the plate. 



The specimen measures 0-52 by 0-15 mm. 



Loc. — Broken Bay, under a stone. 



This species shows undoubted affinity to P. m,ortensenn Hansen, 

 from the Gulf of Siam. This is a little remarkable in view of the 

 fact that the other three species described, all show a closer relation 

 ship to South American forms. But the number of described 

 species is too small to allow of any profitable discussion of inter- 

 relations. 



Family EuRYPAUROPODiDiE Ryder. 

 Genus EuRYPAUROPUS Ryder. 

 The single genus of the Family is characterised by the large de- 

 velopment of the dorsal shields, the first of which projects forward 

 beyond the anterior margin of the head, while the last similarly 

 overlaps the anal segment. They are, in addition, so wide that the 

 legs do not project beyond them, and are heavily sculptured, or 

 ornamented with tubercles and spines, the usual hairs being absent. 

 The tactile setae are not inserted upon them, but either below or in 

 lateral clefts. 



EuRYPAUROPUS sPECiosus, n.sp. (Plate Ixxi., figs.l8-2r). 

 Four specimens of this species were collected under a small stone 

 on a mossy bank at Broken Bay, two adult males, and two im- 

 mature individuals with five and six pairs of legs respectively.
