A new name, Stlchopus trojncalis, is used to replace '"'' Stichopus 

 godefroii'i^ variety b," this so-called variety being here considered a 

 distinct species, as explained in the description of that form. 



Species previously known but now for the first time recorded from 

 the Hawaiian group are: 



Actinopyga parvula. Met^othn ria parva. 



Holotlmria arenicola. Eunjda godeffroyi. 



Mesothuria mnrrayi. 



Previously reported species secured hy the fisheries steamer 

 Albatross: 



Actinopyga obesa. 

 A ctinopyga 'rnaur iliana. 

 Holothuria paradoxa. 

 Holothuria cinerasens. 

 Holothuria pervicax. 

 Holothuria atra. 



Holothuria fusco-ruhra. 



Holothuria pardalis. 



Holothuria impatiens. 



SticJiopus tropicalis. 



( ^Stichopus godeffroyi var. b, of authors. ) 



Synaptula kefersteinii. 



Species recorded from the Hawaiian Islands, but not taken by the 

 fisheries steamer Albatross: 



Actinopyga nobilis. 

 Holothuria kapiolaniee. 

 Holothuria monacaria. 

 Holothuria vagabunda. 

 Holotlmria humilis. 



Holotlmria inhabilis. 

 Holotlmria verrucosa. 

 Lahidodemas semperianum. 

 Sticliopiis ch loronotos. 



All the known species of Hawaiian holothurians have been included 

 in the keys in this report, and short diagnoses of those not taken by 

 the fisheries steamer Albatross are inserted in the proper place, but 

 are marked in all cases by an asterisk (*). It is believed that this 

 method will render the report more useful to the general naturalist, 

 since literature on the subject is often inaccessible. The various lists 

 will prevent confusion concerning the species actually secured by the 

 expedition of 1902. 



I wish to acknowledge my indelitedness to Mr. Wilfred H. Osgood, 

 of the Bureau of Biological Survey, and to Miss Mary J. Rathbun, 

 of the U. S. National Museum, for looking up references which were 

 not accessible to me; and to Dr C. H. (Hlbert, of Stanford University, 

 and Dr. Hubert Lyman Clark, of the jNIuseum of Comparative Zoology, 

 for advice on several matters. Dr. Clark has also kindly looked over 

 the page proofs. 



While correcting the galley proofs I received Koehler and Vaney's 

 important memoir entitled An Account of the Deep-See Holothuriodea 

 collected by the Ro3'al Indian marine survey ship Investigator. So 

 far as possi})le I have taken account of K(chler and Vaney's species in 

 the descriptions of the Albatross material. It has not, at this late hour, 

 been possible to accord to this work the space and attention that it 

 deserves.
