Cliffs, and indicates the identity of Echinolampas ovulum 

 and E. Gainhierensis. 

 1885. Prof. Tate, " Southern Science Record," Janry., p. 4, 

 describes Fihularia gregata, n. sp., and Linthia antiaus- 

 tralis, n. sp. 



1887. Prof. Duncan, "Quart. Journ. Geol. Soc," vol. XLIIE., p. 



411 e^ seq., gives a list of species of the Echinoidea of 

 the Australian Tertiaries, which is essentially the same 

 as his former one published in 1877, as the only 

 additional species admitted are Salenia tertiaria and 

 McCoy's three species of Fericosinus. However, a 

 revision is made of the specific characters of some 

 species; a new genus Ortholophus is erected for his Tenxne- 

 chinus lineahis ; Rhynchopygus dyasteroides is altered to 

 Hoi aster difficilis; but Megalaster is retained, as is also 

 Clypeaster folium, Ag., but as a variety ; of living 

 species Echinarchinus parima is dropped out, but 

 Schizaster ventricosus is retained on an imperfect 

 specimen. 



1888. Prof. Tate, " Proc. Roy. Soc, New South Wales," p. 240 



et seq., gives a list of genera of Echinoids, and the 

 number of species to each from the Older Tertiary of 

 Australia, amounting to 29 genera and 49 species. The 

 following emendations have arisen : — Temnechinus in- 

 cludes Paradoxechioiiis Rnd Ortholophus; Murravechinus 

 (n. gen.) is a Ccclopleurus; Arachnoides is Monostychiay 

 but the genus Arachnoides will stand, as a species has 

 since been found in the Miocene at the Gippsland Lakes ; 

 Cardiaster is to be added, though inadvertently omitted, 

 it was included in his list of 1877 ; Bhynchojyygus should 

 be expunged. 



1889. Prof. Duncan, "Journ. Linnean Society, London," in a 



revision of the Genera of the Echinoidea, makes special 

 reference to a few of our Tertiary species ; but persists 

 in the retention of his genus Megalaster. 



1890. A. C. Gregory, "Geological Magazine," has anticipated me by 



describing several new species, some belonging to genera 

 not hitherto known to form part of the Echinodermal 

 fauna of the Australian Tertiary, except through their 

 introduction in my lists of genera published in 1877 and 

 1888 ; e.g., Hemiaster, Cardiaster, and Cassidulus. All 

 of them have been distributed to various public museums 

 with M.S. names, which are added as synonyms in the 

 appended " List of Described Species " for tlie informa- 

 tion of those to whom they have been sent.
