The continent of Australia and its adjacent islands have 

 hitherto proved singularly disappointing in the production 

 of interesting types of Chilopoda. Setting aside Cerma- 

 t obi us, Avhich was discovered some fifteen years back iu the 

 island of Adenara, none of the genera known up to the 

 present time from the Australian region throw special light 

 upon the phylogeny of the families of this class ; none can 

 be regarded as archaic forms that have found refuge in this 

 southern tract of land. Collections made in various districts 

 of the country have yielded specimens of Scutigera, 

 Henicops, Lithobius, Scolopendra, Cryptops, Geo- 

 philus — genera which may be met with on a single hillside 

 in almost auy part of Southern Europe; of Co rmocephalus 

 and EthmostigmuSj which in an almost equal degree are 

 characteristic of tropical Africa or the Oriental region. The 

 entire fauna, in short, bears the stamp of comparatively recent 

 origin by immigration from South Eastern Asia, with perhaps 

 an infusion from the Ethiopian region or Madagascar. 



In 1892, however, I received from Mr. G. M. Thomson, of 

 Dunedin, New Zealand, a small consignment of Myriapods 

 from the summit of Mount Rumney, Hobart, Tasmania, which 

 completely falsified the opinion that the Antipodes hold nothing
