On the Occurrence in the Yorcdale llochs of Wenslei/dale of Fish and Am- 

 phibian Memains. Bi/ W. IIorne. 



The remains occurred in thin limestones above and contiguous to the main lime- 

 stone. Among the fossils were teeth of Cladodus and Pleiirodus, and bones of the 

 limbs of a Labyriuthodont Amphibian. 



On the British Pidceozoic Arcadte. By J. Logan Lobley, F.O.S. 



In this paper the results of an examination of the described species of Lamelli- 

 brauchiata attributed to the familj' Ai'cadie, and occurring in British Palaeozoic 

 roclcs, were given. 



After proposin"; that the sinupallial genera which have hitherto been included 

 in Arcadoe should be removed from that family and constitute a separate group, 

 the author discussed the claims of the various generic distinctions which authors 

 had sought to establish, and thought the following genera might be admitted as 

 having representatives in the Palajozoic strata of the British Islands : — Area (L.), 

 Cucullcea (Lam.), Macrodon (Lvcett), Nucula (Lam.), Cte)iodonta (Salter), Ch~ 

 cuUella (M°Coy), Glyptarca (Hicts), Palaiarca (Hall.) — the species of ArcadiB which 

 had been assigned by various authors to Bi/ssoarca, Cbidophorus, Cypricarditls, 

 Cyrtodonta, Meyamhonia, Pallastra, Tdlinomya, Vanuxemia, &c. being given to one 

 or other of the before-mentioned genera. 



The following summary gives the number of species admitted in each genus, with 

 its stratigraphical range in the Palseozoic rocks : — 



Area, 9 species Ludlow, Carboniferous Limestone. 



CucuUaa, 10 species .... Middle Devonian, Upper Devonian, Carboniferous 



Limestone. 



Macrodon, 1 species .... Permian. 



Nucula, 1 species Permian. 



Ctenodo)ita, 41 species. . . . Tremadoc, Llaudeilo, Cavadoc, Lower Llandovery, 



LTpper Llandovery, Wenlock, Ludlow, I^ower De- 

 vonian, Middle Devonian, Upper Devonian, Car- 

 boniferous Limestone, Coal-measures. 



Cucullella, 4 species Caradoc, Upper Llandovery, Ludlow. 



Glyptarca, 2 species .... Tremadoc. 



Palcearca, 14 species .... Tremadoc, Llandeilo, Caradoc, Upper Llandovery,

Total 82 species, having the following distribution : — Tremadoc, G ; Llandeilo, 3 ; 

 Caradoc, 17; Lower Llandovery, 2; Upper Llandovery, 11; Wenlock, 2 ; Lud- 

 low, 7; Lower Devonian, 1; Middle Devonian, 2; Upper Devonian, 11; Carbo-

On a Horn and Bones found in a Cuttinq in a Street in Maidenhead, BerJcs. 

 By T. Moffat, M.D., F.G.S. 



The horn and bones were found imbedded in flint gravel about six feet from the 

 surfece. They appeared to be much mineralized. There are cuts upon the horn, 

 apparently made when it was fresh and for the purpose of separating it from the 

 skull. The cuts seem to have been made with an edged metallic tool. 



On Geological Systems and Endemic Diseases. By T. Moffat, M.D., F.G.S. 



The author stated that the results given in this confirmed what he had stated 

 in his former papers, viz. that goitre and anaemia are endemic on the Carboniferous 

 system, while they are absent on Cheskire or New Red Sandstone. He wished it 

 to be understood, however, that the observations were made only in the district la 

 which he resided.
