128 " ENDEAVOUR " SCIENTIFIC RESULTS. 



Having now completed the examination of the worms 

 obtained during the cruise of the " Endeavour," it will be 

 convenient to summarise the results of my work, which will 

 entail to some extent a repetition of the introductory remarks 

 in Part I. There it was noted that the " Challenger " 

 obtained fifteen species of Polychaetes in the area covered 

 by the cruise of the " Endeavour," of which twelve were 

 new to science. 



The present collection contains forty -one species, including 

 a fragment of a species of Sigalion, an indeterminable frag- 

 ment of a species of Phyllodocid, and a species of Halodora, to 

 which I have been unable to assign a name. Of these forty- 

 one, five were obtained previously in this region ; seventeen 

 species hitherto recorded in various other parts of the world 

 are now added to the southern Australian fauna ; and I 

 have found it necessary to make sixteen new species, one or 

 two of which may, however, be merely varieties of already 

 known forms ; and to erect one new genus for a Nereid, namely 

 Cheilonereis. 



The " Challenger " obtained the fifteen species from four 

 hauls ; the " Endeavour " secured these forty -one species 

 in twenty-six hauls, but it must be borne in mind that in the 

 latter cruise the primary object was an economic one in 

 connection with the Fisheries, and it is highly satisfactory 

 that so many worms, many of them of small size, should 

 have been noted and so carefully preserved by the late 

 Mr. C. T. Harrisson, the Biologist on board. In many instances 

 a single individual of a species was received by me and, 

 therefore, presumably the only one captured. We have a 

 very small but fairly representative sample of the fauna of 

 these deeper waters, for the majority of the families is repre- 

 sented by one or more genera ; the Polynoinse and Eunicidae 

 being well represented. There are some interesting omis- 

 sions, however, for instance no member of the sub-family 

 Aphroditinse were included, which is rather unexpected, as 

 they are deep-water forms of large size. 



The families Syllidse, Ariciidae, Spionidae being small worms 

 might easily be overlooked in sorting out the contents of the 

 dredge, and burrowing as they do for the most part in mud or 

 others living amongst the CoraUine Algse near shore are not 

 urmaturally absent. 



One would perhaps have expected more TerebelHdse, of 

 which only on& individual was obtained, and also members 

 of the allied famihes.
