5. P. shephardi, Sayce, 1900a. Blind, from a surface spring at 



2,000 ft., near Melbourne, Australia. 



6. P. kirkii, Chilfcon, 1906. Blind, from fresh-water lagoon, New 



Zealand. 



6<z. P. k. var. dunedinensis, Ghilton, 1906. Blind, from streams 

 near Dunedin, New Zealand. 



7. P. spinosus, G. Smith, 1909. With eyes, from the Great Lake, 



3,000 ft., Tasmania. 



This species is very similar to P. tasmaniae, especially as regards 

 the telson and uropods. P. tasmaniae was described from a dried 

 specimen, and Smith apparently has not seen this paper, since 

 he quotes Thomson's record of P. australis from Mt. Wellington 

 and makes no reference to Thomson's own correction in 1894. 

 According to Thomson the young of P. tasmaniae differs from older 

 specimens (| inch) as regai'ds the spines on the body, so that it 

 is possible that P. spinosus (Smith gives its length as 15-25 mm.) 

 is only a larger form of P. tasmaniae, though the 5th pleon segments 

 differ. 



8. P. brevicaudatus, G. Smith, 1909. With eyes, from the Great 



Lake, 3,000 ft., Tasmania. 



2. GEN. PHBEATOICOPSIS, Spencer and Hall, 1897. 



1. P. terricola, Sp. and Hall, 1897. With eyes, burrowing in the 

 banks of the Upper Gellibrand Eiver, Victoria, Australia. 



3. GEN. PHEEATOICOIDES, Sayce, 1900. 



1. P. gracilis, Sayce, 1900. Blind, from surface runnels, Gippsland, 

 Victoria, Australia. 



4. GEN. HYPSIMETOPUS, Sayce, 1902. 



1. H. intrusor, Sayce, 1902. Blind, in the burrows of the land- 

 crayfish Engaeus, Tasmania. 



From the above it will be seen that the family is distributed thus : 

 New Zealand 3 species (1 genus) ; Australia 4 species (3 genera) ; 

 and Tasmania 5 species (2 genera). Only one species is common 

 to any two regions, namely, P. australis from Australia and 

 Tasmania. The distribution of the family is thus a very narrow 

 one. Sayce, 1902, remarks that it would be interesting to know
