bear a very fine, fairly long pilosity. The penes are stout and large, 

 reaching, without setae, to the middle of the fourth segment. The 

 last legs are longest. The hairs of coxa and trochanter are baton- 

 shaped, none of them biramous, and those of the coxa much larger 

 than those of the trochanter. 



This specimen measures 0-75 mm. in length, by 0-15 mm. in 

 breadth. 



Loc. — Broken Bay. 



This species occupies a somewhat isolated position. In the form 

 of the antenna, and in the short, knob-like styli and long hairs of 

 the anal segment, it shows affinity with P. inornatus Hansen, from 

 the Argentine, but the form of the anal plate and sternum of anal 

 segment differs considerably from those of the Argentine forms. 



Pauropus burrowesi, n.sp. (Plate Ixxi., fig. 17). 



Of this species, a single immature individual, with eight pairs of 

 legs, was available; but I have ventured to describe it on account 

 of the remarkable form of the anal plate, which is only comparable 

 with that of a Siamese form, from which, however, the present 

 species is easily distinguished by several features. As I have only 

 a single specimen, which, owing to its obstinate opacity, is diffi- 

 cult to describe in detail, I content myself with its outstanding 

 features. 



The antenna has both rami short, the lower extremely so, and 

 only one-half the length of the upper. The former has its an- 

 tero-lateral angle obliquely truncated, bearing the anterior flagel- 

 lum, which is not quite one-half the length of the posterior. The 

 upper ramus is short, its flagellum thrice its length, and one-fifth 

 longer than the posterior flagellum of the lower ramus. The 

 globulus is conspicuously large, as wide as the distal end of the 

 upper ramus, with a stalk about one-half its diameter. All the 

 flagella are much swollen distally, the last four or five rings being 

 distinguished from the rest by a clearly defined central axis run- 

 ning through them, of the same diameter as the little terminal 

 bulb, with which it connects. The anal segment and plate have 

 very much the same general features as in P. mortensenii Hansen,
