cularform, about a line in diameter, and rather closely set in a single series.The fore-part of the orbit is very unequivocally displayed, the smoothunder or inner surface of the bone forming that part being entire;and this shows the fore-part of the orbit to be formed, partly by themaxillary, partly by a lacrymal or prefrontal bone in close suturalunion therewith,—a structure which does not exist, to my knowledge,in any recent or fossil fish with a dentigerous superior maxillary bone.Where the substance of the bone has been detached so far as to exposethe exterior layer in contact with the coal, as e.g. on the frontal andpart of the prefrontal bones, the exterior surface of those bones isshown to have been impressed by subhemispheric, or elliptical pits,from 1 line to 1^ line in diameter, and with intervals of half thatextent: and this coarsety pitted character agrees with that presentedby the outer surface of the similarly broad and flat crania of the Quart.Joum.Geol.Soc.VolXPl.lX

Trematosaurns, Capitosaurus, andLabyrinthodon proper. The evidence of this structure presented bythe tubercles of carbonaceous matter that filled the depressions in thebone, is at the same time evidence of the pulpy or plastic state ofthe carbonaceous matter when it made the cast of the sculpturedouter surface of the cranium, which surface it now shows in relief. A small microscopic section of the osseous tissue, which Mr.Quekett has had the kindness to prepare, shows very distinct andwell-defined bone-corpuscles or cells, of an elliptic or oval figure,scattered throughout the tissue, at distances of from one to two orthree of their own long diameters: without any appearance, in thesection prepared, of vascular canals. The size of these bone-cells isless than those in the Batrachian reptile di
