It is unfortunate that Mr. Etheridge placed tliese two forms 

 specifically together. They are quite difterent, and are so 

 treated by the writer.. In describing them, their differences 

 will be fully shown. As the Queensland form was the one for 

 which the specific name grandis was first suggested by Mr. 

 Etheridge, it is proposed that it should continue to be known by 

 this name. To tlie New South Wales one, a new specific term 

 will be given. 



The name grandis is quite appropriate for either of the forms; 

 because their pygidia are larger than those of any other known 

 Carboniferous trilobite. 



5. Phillipsia woodwardi Etheridge, Junr., Geol. and Pal. 

 Queensland and New Guinea, 1892, p. 215, PI. 7, figs. 11, 13; PL 

 44, figs. 5, 6. 



This is a singular species, to which some reference will be 

 made later on. 



6. Besides the foregoing species of Phillipsia, which have been 

 specifically determined, Mr. Etheridge described two pygidia 

 from Binge Berry, Rouchel Brook, and near Paterson, respect- 

 ively, and referred them to this genus, but did not give them 

 specific rank.
