i806 Geological Society : — 



Binney subsequently went over the district with Mr. R. B. Brock- 

 bank, and found that, although the country is thickly coated with 

 boulder-clay or till, yet lias-limestone and shales were observable 

 in several spots, in wells, streams, &c., especially at Quarry Gill, 

 Fisher's Gill Farm, and in Thornbybrook, south-east of Aikton. 

 Gryphcea incurva and other GryphcecB, with Oysters and Ammonites, 

 characterize these beds. The area occupied by the Lias is known to 

 extend under the rising ground lying between Crofton and Orton, on 

 the south, and the Solway, on the north, comprising Aikton, Thornby, 

 Wiggonby, Oughterby, and probably other places on the rising 

 ground between the]^Carlisle and Maryport, and Carlisle and Port 

 Carlisle Railways. 



2. " On the Fossils of the Lingula-flags or Zone Primordiale. 

 — I. Paradoxides and Conocephalus from North America." By J. 

 W. Salter, Esq., F.G.S., of the Geological Survey of Great Britain. 



After briefly noticing the relations of the " Zone Primordiale " in- 

 stituted by M. Barrande, the author described the remains of a large 

 Paradoxides sent from the vicinity of St. John's, Newfoundland, by 

 Mr. Bennett. The fossil belongs to a new species of Paradoxides, 

 the largest yet known (d^ inches broad), and termed P. novo-re- 

 pertus by Mr. Salter. A new species of Conocephalus, from Georgia, 

 was also described from a specimen brought to England by Dr. 

 Feuchtwanger, and placed in the Great Exhibition of 1851 ; it is 

 named C. antiquutus by the author. As these two genera have as 

 yet been known only in the " Zone Primordiale," Mr. Salter re- 

 gards the above-mentioned specimens as indicative of the existence 

 of that geological formation in the countries here mentioned. 



The author also referred to an obscure specimen of Asaphiis, from 

 the " Calciferous sand-rock" of Canada, which he once, but on in- 

 sufficient grounds, published as a Paradoxides. 



3. " On a new species of Dicynodon {D. Murrayi) from near 

 Colesberg, South Africa." By Prof. T. H. Huxley, F.R.S., Sec. 

 G.S. 



For the original specimen from which Prof. Huxley first obtained 

 (in the spring of last year) evidence of the existence of this species, 

 he was indebted to the Rev. H. M. White, of Andover, who subse- 

 quently put the author in communication with the discoverer of the 

 fossil, Mr. J. A. Murray ; and the latter gentleman having written 

 to his father, resident in South Africa, obtained for Prof. Huxley a 

 large quantity of similar fossil remains. One specimen in particular, 

 having been carefully chiselled out by Mr. Dew, afforded a complete 

 skull of this peculiar and previously undescribed species of Dicy- 

 nodon. 



The author described the distinctive features of this skull in detail. 

 Dicynodon Murrayi is distinguished from all the already known 

 species by the following characters : — 



1. The plane of the upper anterior face of the nasal and premax- 

 illary bones would, if produced, cut that of the upper face of the 

 parietal at an angle of about 90°.
