From the Hawaiian Islands until now there are known only the followin;^ species 

 of Myriopoda :

 Mem. Mex. Myr., p. 39, fig. 18, Kauai, Lihue". — ? /ii/iis angniinis Karsch, Sitz.-Ber. 

 Ges. Naturf. Freunde Berlin, 1880, p. 7, Hawaii. 



In the collection of Hawaiian Myriopoda that I have had the pleasure of studying 

 through the kindness of Dr D. Sharp, I have recognised 4 species of Chilopoda and 

 16 of Diplopoda, of which only the Laiiiiioiivx spiss/ts and Orthomorplia gracilis were 

 recorded by previous authors; ot the other species one, Diplomliis liiscits (Mein.), is an 

 european species imported into the Hawaiian Islands, the others are all new to science ; 

 they are : Chilopoda : Lithobins hazvaiiensis, Laniyctes fiilvicornis Mein. var. haivaiiensis, 

 L. heterotarsus ; Diplopoda : Polyxenus hazvaiieiisis, Aporodesminus (gen. nov.) zvallacei, 

 Dinierogonus aveburyi, D. sharpi, D. shiplcy, D. carpeiiteri, D. beddardi, D. pococki, 

 D. sedgwicki, D. sinclairi, D. lankesteri, D. harnicri, D. perkinsi, D. koebelii. 



All the Chilopoda here recorded belong to cosmopolitan genera, but the La^nyctes 



heterotarsus is interesting for the very peculiar structure of the tarsus in the last 



ambulatory legs.
