this species is nearly world-wide, being cosmopolitan or ubiquitous 

 in every sense of the word, Strzelecki, in his ' Physical Description 

 of New South Wales and Van Diemen's Land,' does not seem to 

 have met with it there ; but a representative shell, S. tasmaniensis, 

 Morris, occurs in rocks of the same age : in many respects this shell 

 resembles our Queensland species ; but the hinge-line is wider, and 

 the cardinal angles are less rounded.

This shell occurs in the Silurian, Devonian, and Carboniferous rocks 

 over large areas of the globe, and abundantly in the Devonian series 

 of the Gympie gold-bearing beds in Queensland. Our shell differs 

 in no respect from the well-known forms described by Wahlenberg, 

 Sowerby, Phillips, and De Koninck. Mr. Davidson, in his great work 

 upon the Palaeozoic Brachiopoda, in the Mem. Pal. Soc, has in each 

 Monograph described and figured this ubiquitous species. Producta 

 depressa, Sow. M. C. t. 459. fig. 3, Leptcena depressa, Kon., Producta 

 analoga, Phil. (loc. cit.), are all one and the same species. I have 

 submitted the specimen to Mr. Davidson, who recognized it to be the 

 above species without doubt.

Reference is made to this widely distributed shell above. It is 

 of importance to figure this species from this rock and locality, from 

 its occurrence with, certain other fossils, and also as bearing upon 

 the question of associated forms of life in rocks yielding gold at Lady- 

 Mary Reef, Gympie diggings.

This shell has been noticed on the preceding page, and more 

 perfect specimens figured on Plate XYI. figs. 3, 4, 5. This shell, like 

 Strophomena rhomboidalis, is associated with the auriferous deposits 

 at Lady-Mary Reef, Gympie. Nearly all the rock-specimens contain 

 Producti, and Strophomena rhomboidalis, var. analoga, associated 

 with the above shell and abundantly distributed.
