The death of Sir R. 1. Murchison, in the eightieth year of 
his age, at London, on the 23d instant, was announced by the 
Secretary. 
The loss by shipwreck, in a recent storm, on Lake Superior, 
of James T. Hodge, a member of the society, was announced 
by Secretary, with appropriate remarks. 
Prof Cope made some general observations on the extinct 
Batrachian Fauna of the Carboniferous of Linton, Ohio., based 
on studies of material obtained by Prof. J. 8, Newberry, Di- 
rector of the Geological Survey of Ohio. 
Twenty-seven species had been discovered up to the present time, 
and not one of them was a reptile ; twenty-three of these were referred 
to the following genera: Pelion, Wyman, 1 5 Sauropleura, Cope, 3; Tu- 
ditanus, Cope, 43 Brachydectes, Cope, 1; Oéstocephalus, Cope, 6; Cocy- 
tinus, Cope, 1; Molgophis, Cope, 1; Phlegethontia, Cope, 2; Colosteus, 
Cope, 8; Hurythoraa, Cope, 1. 
Tuditanus, Cocytinus and Phlegethontia were described as new genera. 
The first represented Dendrerpeton, but possessed the usual three thoracic 
shields, a character not yet found in the former genus, 
Phiegethontia embraced slender snake-like forms allied to Molgophis, 
but without ribs. Cocytinus was a branchiferous genus having four 
branchihyal bones, two basals branchikyals and two ceratohyals on each 
side, and with conic teeth in the anterior portion of the mandible only, 
on an expansion or dental plate. Limbs none in front. 
Oéstocephalus was defined as having the three pectoral shields, poste- 
rior limbs only present and weak ; head lanceolate ; ventral armature of 
packed osseous rods en chevron ; neural and haemal spines of caudal 
vertebrae expanded and fan-like. The six species were enumerated, viz : 
O. remex, Cope, O. pectinatus, C., O. marshti, C., O. curoidens, C., O. 
vinchellianus, ©., O, serrula, C., the last three being new to science. 
Other new species were described, as Sauropleura longipes, C., and 8. 
brevipes, O., Tuditanus brevirostris, C., 7, mordax, C., and 7. radiatus, 
C., Cocytinus gyrinoides, C., Rhlegethontia linearis, C., was indicated as a 
species with lanceolated head, no ribs, a very elongate tail, and without 
limbs or ventral or thoracic armature. Phlegethontia serpens, C., was 
a larger species. A new Colosteus, C. pauciradiatus was added, and an 
allied form described as Hurythorax sablaevis. The pectoral median 
shield is subround and nearly smooth, and belonged to an animal of four 
feet in length. 
Sauropleura, Oocytinus, Molgophis, Phlegethontia were enumerated as 
genera in which pectoral shields had not been observed, and Pelion and 
Tuditanus were characterized as the broad-headed types.
