Hurron.—On the Geographical Relations of the N.Z. Fauna. 249 
ARACHNIDA, 
Of Spiders we have about 100 species, but my knowledge of them is very 
limited. Mr, Pickard-Cambridge, in a letter to me remarks, “all the spiders 
you now send (from the Auckland province), except one or two, are strikingly 
European in appearance, nothing tropical- -looking among them.” Perhaps the 
most remarkable fact is the occurrence in the Chatham Islands of a species 
of water-spider (Argyroneta) of which only one other Species, inhabiting 
Europe, is known. Spiders are very numerous in New Zealand, owing no 
doubt to the abundance of Diptera, on which order they chiefly prey. 
CRUSTACEA. 
Of Crustaceans 106 species have been described as coming from New 
Zealand, but my knowledge of this 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 ; 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 forms we have two species of earthworm (Lumbricus) 
and a member of the peculiar genus Peripatus, found only in South America, 
the Cape of Good Hope, and the West Indies. 
SCOLECIDA. 
The most remarkable fact in this class is the occurrence of two or three 
species of land Planarians, the so-called “ land-leeches,” one or two of bees 
belong to the genus Bipalium, found only in India, China, and Japan. 
ECHINODERMATA, 
Of Echinoderms we have seventeen species of star-fish, eight sea-urchins, 
and eight holothurians. Of these twelve star-fish, six sea-urchins and all the 
holothurians appear to be endemic. Of the others Ophionereis Jasciatus is found 
at the Chatham Islands, Pentagonaster pulchellus at the Chatham Islands and 
in China, Othilia luzonica in the Philippine Islands and Vera Cruz, while we 
also possess species apparently 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 there, so that it must have migrated to us direct, and not 
have come vid Australia. We also possess a species of Pteraster, a genus 
found only in South Africa and Northern Seas. Of the sea-urchins, Cidaris 
tubaria, and Echinobrissus 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.
