hut of Mr. M^Dougal, a small patch of ferruginous grit caps a single 

 hill-top ; and in it numerous specimens of Panopcea jpl'wata are found 

 imbedded. 



From Gordon Downs, at the head of E.oper Creek, the Rev. W. 

 B. Clarke has forwarded me a suite of specimens, which, on Mr. 

 Etheridge's authority, may be referred to the same horizon as the 

 Pelican-Creek beds. 



They consist of the following genera: — 



Panopffia. 



Pholadoroya. 



Tancredia. 



CueuUaBa. 

 Homomya *. 

 Pleurotomai'ia *. 



Consideriaig these Pelican-Creek and Gordon-Downs strata the 

 representatives of a lower horizon in the Mesozoic series than those 

 of the Plinders river, the direct representatives of the Flinders 

 rocks have as yet been unrecognized to the east of the dividing 

 range. A very large portion of Queensland, however, as far north 

 as 20° S. latitude, between the dividing range and the eastern sea- 

 board, is covered with a series of beds, chiefly freshwater, contain- 

 ing abundance of plant-remains, in the upper portion of which a 

 few beds only contain a fauna which seems, on palseontological evi- 

 dence, to occupy a position between the Gordon-Downs and Flinders- 

 river series. 



These beds crop out at the toAvnship of Maryborough, and have 

 been used by the Corporation of that thriving place as quarries for 

 road-metal. The contained shells have been named and arranged 

 by Mr. Etheridge as follows :— 



Cypi'ina expansa, Eth. PI. XIX. fig. 1. 

 Trigonia nasuta, Eth. PL XIX. fig. 2. 

 Cucullrea robusta, Eth. PI. XX. fig. 1 .

'Nucula gigantea, Eth. PL XX. fig. 4. 



quadrata, Eth. PL XX. fig. 3. 



Leda eloBgata, Eth. PL XX. fig. 5. 

 AvicuLa alata, Eth. PL XX. fig. 8.

 Natica lineata, Eth. PL XXI. fig. 1. 

 Pulvinites? PL XIX. fig. 3. 

 Cardium? PL XIX. fig. 4. 



Up to the present time, within all the area marked on the map 

 as occupied by Carbonaceous Mesozoic strata, only the Maryborough 

 beds have yielded fossil remains other than plants. On tributaries 

 of the Condamine, Brisbane, and Mary rivers, where numerous 

 coal-seams are known to exist, several of which have been and are 

 now being worked, these plant-remains are of the same character. 



A collection from two localities has been examined and named by 

 "W. Carruthers, Esq., F.R.S., F.G.S. A suite from the Tivoli coal- 

 mine he finds to consist of: — 



Pecopteris Daintreei. 



odontopteroides. 



Cardiocarpon australe. 

 Cyciopteris cuneata. 



Schizopteris elongata. 

 Tainiopteris Daintreei. 



gracilis. 



austrah's.
