HOLOTHUEIANS OF NEW ZEALAIfD. 23 



Dunedin Museum, and am greatly indebted to him for named 

 specimens of " Thyone caudata^'' " JEchinocucumis alha,^' and 

 especially his own " Chirodota dunedinensis" as well as for a new 

 species of Psolus collected at the Macquarie Islands. 



Unfortunately the type specimens of Hutton's " Cucumaria 

 Thomsoni" "Lahidodesmus turbinaf us," and. "Holothurialtohsoni " 

 had been sent from Dunedin to the Colonial and Indian Exhibition 

 in London, and thence presumably to the British Museum ;, 

 so that I. am unable to add anything to our knowledge of these 

 species, and can only hope that they will be re-examined by the 

 Museum authorities. 



I am also indebted both to Captain Hutton and Professor 

 Parker for several additioual specimens of that remarkable 

 Holothurian Caudina {Molpadia) coriacea, and to Captain Huttou 

 again for the loan of specimens of ColocMrus ocnoides, n. sp., and 

 Cucumaria Huttoni, n. sp., from the Canterbury Museum. 



Mr. H. Earquhar, of Wellington, very kindly gave me another 

 specimen of " Echinocucumis alha" dredged in Wellington 

 Harbour, and allowed me to make use of a manuscript Catalogue 

 of New Zealand Echinodermata compiled by himself. 



While I was staying at Wellington, my friend Mr. H. B. Kirk 

 took me to some of his favourite collecting-grounds in Cook 

 Straits, where we secured living specimens of 8tichopus mollis, 

 Hutton sp., and ColocMrus calcarea, n. sp. Mr. Kirk also sent 

 me a further supply of these species to Christchurch. 



To all these gentlemen I wish to express my very sincere 

 thanks. 



The only other Holothurians known from New Zealand are 

 those collected by the ' Challenger ' Expedition and described by 

 Theel. I have of course been unable to examine the types of 

 these, but the full descriptions and figures given in the ' Chal- 

 lenger ' Eeport render this unnecessary. Indeed I ought also 

 to express my indebtedness to the admirable monographic account 

 of the group given in the ' Challenger ' Report, as but for it I 

 could not have completed this investigation, for I need hardly 

 point out that in the absence of zoological libraries such a piece 

 of work becomes almost impossible. 



2. Sttmmaet of Eesults. 



The majority of the already known species of New Zealand 

 Holothurians have been re-examined, especially with regard to
