Cormocephahts aurantiipes marginatus, Kraepelin, Mit. Nat. 

 Mus. Bamburg, xx, 1903. 



According to Kraepelin, 1903 : — 



" Der Hauptform durchaus gleichend, aber die letzte Riicken- 

 platte oline Medianfurche. Die Berandung der Riickenplatten 

 beginnt bei den vorliegenden Stiicken stets ini 7 Segment. Die 

 Riickenplatten sind fast immer griin berandet." 



Here also the margins on the terga begin with the seventh 

 segment. 



Loc. — Narrabri, N. S. Wales ; one young specimen. 



CORMOCEPHALUS BREVISPINATUS SULCATUS, Sltbsp. HOV. 



(Fig. 5.) 



Dark olive green ; legs and antenna? paler ; toxicognats rusty. 



Length 76 mm.; breadth of first tergum 6*50 mm. of second, 

 6 mm. of sixteenth, 6*50 mm. of the twenty-first, 5 50 mm. 

 (measurements taken on the largest specimen). 



Head plate, first tergum and maxillipedes obsoletely punctured. 

 Head plate of even length and breadth (4 50 mm.) ; anterior 

 margin rounded ; posterior margin angular with the apex 

 engaged under the anterior margin of the first tergum. A pair 

 of triangular, short, but transversely stretched plates 2 exist 

 behind the posterior angles of the head. First tergum wide but 

 without any furrow. The two usual median furrows are to be 

 seen from the second tergum to the twentieth. The marginal 

 furrows are distinct on the last five to eight terga, but scarcely 



1 The trinomial nomenclature is in aecord with Dr. Brolemann's M.S. 

 It is not used in the Australian Museum. 



2 Several authors call these plates " Basalplatten ", a name which does 

 not seem appropriate. The so-called basal plate of Geophilids is the tergum 

 of the maxillipedes ; but since, in Scolopendrids, the latter is fused with the 

 first dorsal tergum, it is likely that these plates lying in front of it belong 

 to the last cephalic segment, viz. to the second pair of maxillre. It is 

 proposed therefore to call these plates " postcephalic ".
