chamberlin: myriopoda of the Australian region. 231 



In the anterior legs of the male the coxal processes much less pointed 

 than in Z. ferruginopcs; those of the third legs narrowest, distally 

 rounded; the following ones subquadrate in outline, being distally 

 truncate. 



Number of segments, fifty-seven or fifty-eight. 



Diameter (male), 4.5 mm. 



656. Zygostrophus urallanus, sp. nov. 



Type.— M. C. Z. 4,799. Paratypes.— M. C. Z. 4,800. New 

 South Wales: Salisbury Court near Uralla (W. M. Wheeler). 



Presenting a very diflferent appearance from the other species 

 because of the broader and lighter pale stripes, each pale stripe, 

 testaceous of a dilute ferruginous cast, embracing the entire meta- 

 zonite and dorsally often encroaching on the prozonite; prozonite 

 black, becoming lighter down the sides so that the pleural region 

 appears lighter than the dorsum; covered zone also light colored. 

 Anal segment, collum and head blackish or greyish black, the coUum 

 narrowly margined with the fulvoferruginous and the anal scutum 

 and valves also paler caudally. Legs dilute ferruginous. 



Sulcus across vertex and below as usual. Vertex strongly, finely 

 roughened with several impressions shagreened. Eyes more strongly 

 narrowed cephalad than in Z. fcrruginopes, fully twice their diameter 

 apart. 



The lower edge of the collum short, rising obliquely and meeting 

 the anterior edge at an angle as in Z. ferruginopcs but a little convex, 

 not incurved as in the latter form. 



Metazonites longitudinally striate below in the usual manner, these 

 striae extending only half way up the side to the pore, above them a 

 series of impressed areas along the suture. The prozonites on the side 

 with a dense network of very fine curved lines, running obliquely or 

 vertically; prozonites dorsally with numerous circular and horse- 

 shoe-shaped impressions which decrease in size from the suture. 



Valves exceeding the anal tergite; mesal borders strongly elevated. 



In the gonopods the median plate has its distal piece formed pre- 

 cisely as in Z. digitulus but proportionately longer and the sides not so 

 strongly bulging at proximal end. The coxal plates of the anterior 

 gonopods have the tips of their cornuate processes covered by the 

 distal end of the median plate. The posterior or telopodite division 

 of the anterior gonopods of a very different form, the distal end not
