chamberlin: myriopoda of the Australian region. 169 



Collum with lower margin evenly rounded, not extending as far 

 ventrad as the second tergite. Margin separated oflF by a furrow 

 below and up the anterior border toward the dorsum. 



The ordinary segments deeply constricted, the metazonite, however, 

 rising much higher than the prozonite. Pore located well caudad of 

 the encircling furrow. Somites smooth above; longitudinally striate 

 across both zones ventrally and a little distance up the sides. Meta- 

 zonites normally clothed with numerous fine, suberect hairs. 



Anal scutum long, rounded or nearly straight caudally, exceeded 

 by the valves. Valves not margined. 



Number of segments from forty-eight to fifty -eight. 



Length (female), to 25 mm. Greatest width, up to 1.2 mm. The 

 males smaller. Body constricted several segments caudad of head, 

 then enlarging to behind middle and then again narrowing caudad.

Ti-PE.— M. C. Z. 4,829. Paratypes.— M. C. Z. 4,830, 4,831, 

 4,832, 4,833. Fijis: Lasema, Waiyanitu, Vanua Ava, Lomati (W. M. 

 Mann). 



A smaller species than N. fijiana from which it may be distinguished 

 at once in having a broad, fuhous to ferruginous stripe along the 

 dorsum, a stripe along each side alone remaining black as the venter 

 and lower part of the sides are light colored like the middorsal stripe. 

 Anal segment black or mostly so. Legs irregularly dusky over a ful- 

 vous background. Antennae dark, the seventh article not abruptly 

 paler, fulvous, as it is in N . fijiana. 



Antennal articles shorter; the fifth more strongly constricted at base. 



Collum more narrowed below, the lower end set off as a narrow 

 rounded process. The segments constricted deeply as in the geno- 

 type. Both prozonites and metazonites subdensely clothed with 

 hairs which are shorter and straighter than in the other species. Striae 

 obscure. 



Number of segments, forty-four to fifty-two. 



Length (female), only to 14 mm.

Type.— M. C. Z. 4,834. Fijis: Waiyanitu (W. M. Mann). 

 In size smaller than X. fijiana, being about the same as lineata.
