Ohs. — I have referred to this species a few small Spirifers 

 from Coral Creek and other localities, with a deep wide sinus 

 in the ventral valve, bordered on each side by three pro- 

 minent ribs, and the rudiment of a fourth. In the dorsal 

 valve the fold is broad and well marked, and there are the 

 same number of ribs as in the ventral. There are indications 

 of the divided mesial lobe or fold in one of the specimens, 

 but in the other dorsal valve the fold is too much pinched up 

 to show this distinctly. The characteristic concentric laminae 

 are also visible in another of the specimens. I have com- 

 pared the Queensland examples with the type contained in 

 the Strzelecki Collection, and also with a very typical speci- 

 men from the cliffs at Woollongong, New South Wales, for 

 which I am indebted to my friend Professor A. Liversidge, 

 F.C.S., F.G.S., etc., of Sydney University, and I find that, 

 allowing for difference of age and state of preservation, it 

 may safely be concluded that the specimens collected by Mr 

 Jack belong to this species. 



I am quite in accord with Professor De Koninck in refer- 

 ring one of the shells figured by Professor Morris as Spirifer 

 suhradiatus (G. Sowerby) to the present species. I have com- 

 pared this particular specimen with Morris's type of the latter.* 

 In justice to Professor Morris, it must be borne in mind that 

 he himself hinted at this union. Again, I think it not at all 

 improbable that Professor Dana is correct in placing *S'. pau- 

 cicostata (G. Sow.) as a synonym of S. Dariuinii (Morris).
