Excerpt from Fisheries, Vol. 4: Biological Results of the Fishing Experiments Carried Out by F. I. S. "Endeavour" 1909-14
The collections dealt with in this report consist of the Echinoderms, excepting the Holothurians or Sea - cucumbers (beche-de-mer), or in technical terms the Actinogonidiate Echinoderms, obtained by the Federal Fisheries Investigation Ship Endeavour along the Australian coast south of Lat. 24s. At depths of less than three hundred fathoms, during the years 1909-1914 inclusive. The Holothurians were by mutual agreement sent elsewhere for study.
The collections were sent to me in five instalments and have included altogether one thousand and Sixty-one Specimens representing one hundred and fifteen species, of which thirty nine seem to be new to science and fifteen others are now recorded from Australia for the first time. Others, previously known from northern Australia are now listed from stations south of the tropics, and the extension of ranges in this way is oftentimes very great. Up to the present time (1 July, the list of Actinogonidiate Echinoderms known from Australia was about three hundred and twenty, but owing to numerous cases of incorrect identifications and of inaccurate locality labels, it is impossible to give exact figures. There is no doubt, however, that including the large additions made by the Endeavour, the known Echinoderm fauna of Australia includes more than three hundred and fifty valid Species, aside from the Holothurians.
The geographical distribution of these Species is very inter esting. At least two hundred are endemic, or at least have not yet been reported from elsewhere, while most of the remainder are East Indian Species, ranging southward along the eastern coast of the continent to southern Queensland or even to Port Jackson, New South Wales. In his very interesting and useful paper on the Recent Crinoids of Australia,1 Mr. Austin H. Clark has recognised the existence of a N orth Australian and a South Australian subregion, Port Jackson on the east coast and Shark Bay on the west serving as the approximate boundary between the two. Study of the Echinoderms as a whole (including the Holothurians), however.
