The species is ‘e meee cerium pyriforme, & species very common in 
the Upper Silurian limestones of the region in which it occurs, 
and shorecksreiee: analy of the Niagara formation. The for- 
mation containing the serpentine and limestone “is described as 
consisting of chloritic slates, in some places with hornblende 
cystals, Senet ets and hard jaspery argillaceous rocks.’ 
At Melbourne, in the province of Quebec, rocks, referred by 
Logan to the sultan group, pass upward into a thick series of 
hydromica schists, associated with aneinate bands and lenticular 
layers of crinoidal limestone. Over these, according to Logan, 
lies serpentine in thick beds Gailonbiedly bedded rocks and not

naceous beds, beds of anorthite, steatite, dolomite and red slates. 
pentine, and also disseminated serpentine. The fossils are “ eri- 
noidal joints, fragments apparently of Stenopora,” and tubular 
bodies which m may be portions of Hyolithes or Thea, having an 
interior of calcite and a coating of serpentine. The cells of the 
fossils are sometimes filled with the serpentine; and the crinoidal 
joints are surrounded by it, with dolomite w ithin. 
Slices of these specimens, and those of other localities, were 
made by Mr. Weston hen under the direction of the late Sir
