THE RKCENT CRINOIDS OF AUSTRALIA CLARK. GJl 



present paper. It lias not seemed advisable to burden the above 

 list with references to them, as they obviously were not con- 

 sidered in the preparation of the report, though they are all in 

 jai's which bear on the outside a specific name. 



So much has been written concerning the errors in identifica- 

 tion and descri[)tion of the various species included in this report 

 by all subsequent authors who have had occasion to treat of 

 Australian Crinoids that it seems unnecessary to recapitulate 

 them here. Systematically, the chief point of interest lies in the 

 inclusion of the first two known recent species of Zygometra, 

 which, with the EudioGrinus indivisus described by Semper in 

 1868 fiom the Philippine Islands, make three recent species of a 

 family peculiarly characteristic of the Jurassic rocks of Europe. 



Early in 1885 Professor Bell published a short paper on a 

 collection of Echinoderms which had been brought from Aus- 

 tralia to London in connection with the International Fisheries 

 Exhibition held in that city in 1883. Among them were five 

 species of Crinoids, together with two more from the Solomon 

 Islands ; these are, with their present status : — 

 Antedon milberti ... ... Amphimetra discoidea 



Antedon macronema . . . ... Ptilometra mulleri 



Antedon jnwiila ... ... Comjjsometra loveni 



Actinometra Solaris ... ... Coinatula Solaris 



Actinometra intermedin ... Gomatida Solaris 

 Actinometra jukesi ... ... C omatula jukesi 



In addition there were "several species of Antedon, hitherto 

 undesci'ibed, but here unfortunately represented by single, nor 

 always perfect specimens." 



Three years later Professor Bell reported upon a collection of 

 Echinoderms made by Mr. J. Bracebridge Wilson at Port Philip. 

 Among tliese were three Crinoids, two of which he described as 

 new. One of these, Antedon tvilsoni, is undoubtedly the young 

 of Ptilometra nudleri or of Pt. macronema, and the other, Antedon 

 incommoda, Professor Bell himself pronounced in the following 

 year to be the same as his earlier species Antedon loveni {= Antedon 

 2)nmila), though I found, upon examining the types at London, 

 that it is really a valid form. The i-emaining species was 

 Comanthus trichoptera. 



In the same year the " Challenger Report on the Crinoidea, 

 Part ii. Comatulse " was published. Although only species 

 obtained by the " Challenger " were treated in detail, all the 

 known Comatulids are mentioned and their habitat given. 



The "Challenger" occupied five stations on the eastern and 

 north-eastern coasts of Australia, where Crinoids were found.
