 April 2, 1862. — Prof. Ramsay, President, in the Chair. 



The following communications were read ; — 



1. "On some Remains of Chiton from the Mountain-limestone 

 of Yorkshire." By J. W. Kirkby, Esq. 



These remains consist of eight separate plates of four species of 

 Chiton, found by Mr. Burrow, of Settle, in the Lower Scar Lime- 

 stone of that neighbourhood. These new species, determined by 

 Mr. Kirkby, are Chiton Burrowianus, Kirkby, Ch. coloratus, Kirkby, 

 two species undetermined, and a trace of Chitonellus (?). These 

 appear to be the first Chitons observed in the Carboniferous Lime- 

 stone of England ; but fourteen others, and a Chitonellus, have been 

 found in strata of the same age in Belgium and elsewhere, and have 

 been described by Minister, De Koninck, and De Ryckholt. 



2. "On some Fossil Reptilia, of the Order Ganocephala, from the 

 Coal-measures of the South Joggins, Nova Scotia." By Professor 

 Owen, F.R.S., F.G.S. 



The specimens described in this communication were (together 

 with remains oiXylobius and Pupa) obtained by Dr. Dawson, F.G.S., 

 in 1861, from two fossil stumps of trees, and were referred to in his 

 communication read before the Society on November 6, 1861. Pro- 

 fessor Owen has determined among the specimens submitted to him 

 the following small Reptilian forms — Hylonomus Lyelli, Dawson, 

 H. aciedentatus, Dawson, H. Wymanni, Dawson, Hylerpeton Daiv- 

 soni (nov. gen. et sp.), Owen, and Dendrerpeton Acadianum, Owen. 



3. " On the Occurrence of Mesozoic and Permian Faunae in 

 Eastern Australia." By the Rev. W. B. Clarke, F.G.S. 



Mr. W. P. Gordon having been requested by the Rev. W. B. 

 Clarke to search for fossils in his neighbourhood (between the 

 Balonne and Maranoa Rivers) and in the Fitzroy Downs, Queens- 

 land, was successful in making a large collection of specimens at the 

 Wollumbilla Creek. These he sent to Mr. Clarke, who forwarded 

 them to Professor M'Coy, at Melbourne, for his examination. They 

 prove to be chiefly of Lower Mesozoic genera ; there are also a few 

 (from the Fitzroy Downs, about thirteen miles to the N.W.) which be- 

 long to lower beds. Some fossils long since obtained from the Man- 

 tuan Downs (200 miles N. of Wollumbilla) prove to be of Permian 

 character (Aulosteges or Strophalosia) . Productus and Cyathocrinus 

 (Carboniferous ?) have been met with on the Dawson River. 



Mr. Clarke considers his unfossiliferous Wianamatta Beds, above 

 the coal-measures, near Sydney, as being probably the equivalent of 

 the fossiliferous strata at Wollumbilla Creek. Professor M'Coy 

 regards the latter as belonging to the same formation as the coal- 

 beds with Glossopteris. The fossils are included in the Catalogue 

 of the Products of New South Wales for exhibition in London in 

 1862.
