other articles. Head above level of antennae dusky, almost black in type, 

 the lower region areolated with light. 



Vertex of head crossed by a shallow sulcus. 



Median region of first tergite only moderately elevated, divided into large 

 areas by weak or in part obscure furrows. On the second and third meta- 

 tergites the region between the keels divided into only two transverse series 

 of areas, while the succeeding ones show three. Of these the areas of the 

 anterior series are largest, those of the posterior smallest and most irregular. 

 The keels of the non-porigerous tergites each show three lateral lobes wliile on 

 all the porigerous keels there are four. The caudal border of each keel shows 

 two shorter sulci of which the more mesal is the shorter. The caudal margin 

 of the second keel is nearly straight and transverse, while beginning with the 

 second the margin curves more and more caudad in extending outward to the 

 angle, the posterior corners in the posterior segments being strongly and sub- 

 acutely produced. The caudal margin of the nineteenth segment alone is 

 serrate, the projecting teeth six in number, acute. Last tergite triangularly 

 narrowed caudad, the cauda very narrowly truncate. Above with two trans- 

 verse rows of small setigerous tubercles, one row of four tubercles near the 

 middle and the other but little removed from the caudal end, the lateral 

 tubercles in each row marginal. Caudal margin of the rather large anal scale 

 but shghtly convex between the two marginal setigerous tubercles.

423. JuLus (Ophiiulus) fallax Meinert. 



The occurrence of this common European species in Tasmania and 

 New Zealand, doubtless due to introduction, is worthy of note. It 

 agrees closely with J. falJax as represented in England and Ireland. 

 The gonopods (New Zealand specimens) seem to differ slightly in 

 having the anterior laminae rather narrower and longer with the 

 inner branches not reaching quite so near to the distal end of the 

 outer branch, though more extensi^'e comparisons may show this 

 difference inconstant. The glandular processes of the second legs 

 are longer than wide. Segments as in the typical form.
