Relations of the New-Zealand Fauna. 95 



from New Zealand ; but my knowledge of tliis class also is at 

 present very limited. Professor Dana has remarked that New 

 Zealand has a greater resemblance to Great Britain in its 

 Crustacea than to any other part of the world j but our common 

 salt-water crayfish (Palinurus Lalandii) is found at the Cape 

 of Good Hope and the Island of St. Paul. 



Annelida. 



Our marine Annelids have up to the present been almost 

 entirely neglected. Of terrestrial fonns we have two species 

 of earthworm [Lumhricus] and a member of the peculiar genus 

 Periimtus^ found only in South America, the Cape of Good 

 Hope, and the West Indies. 



SCOLECIDA. 



The most remarkable fact in this class is the occun-ence of 

 two or three species of land-Planarians, the so-called " land- 

 leeches/' one or two of which belong to the genus Bipalium^ 

 found only in India, China, and Japan. 



ECHINODEEMATA. 



Of Echinoderms we have seventeen species of starfish, 

 eight sea-urchins, and eight Holothurians. Of these, twelve 

 starfish, six sea-urchins, and all the holothurians appear to be 

 endemic. Of the others, Opliionereis fasciata is found at the 

 Chatham Islands, Pentagonaster jyulchellus at the Chatham 

 Islands and in China, OtJnlia luzonica in the Philippine 

 Islands and Vera Cruz ; while we also possess species ap- 

 parently identical with Astropecten armatus of South America 

 and Henricia oculata of Europe. It is worthy of special 

 remark that although Australia possesses several species of 

 Pentagonaster^ the Chinese species is not found tliere ; so that 

 it must have migrated to us direct, and not have come via 

 Australia. We also jDossess a species of Pter aster ^ a genus 

 found only in South Africa and northern seas. Of the sea- 

 urchins, Cidaris tuharia and Echinohrissus recens are both 

 found in Australia ; but the latter appears to be very rare in 

 New Zealand, as I have only seen one specimen, which is in 

 the Colonial Museum. 



CCELENTERATA and PrOTOZOA. 



Of these very little is known. Our seven species of corals 

 are all peculiar, as also appear to be many species of Sertula- 

 rians and sponges ; but I know of no facts among these lower 

 animals that will help out the pi'csent investigation, except in 

 the case of Cryptolaria, a genus belonging to the family Ser-
