The Annals and magazine of natural history; zoology, botany, and geology . Figure of the Skull, one thirty-sixth of the natural size. At X a piece of the great cartilage which originally filled the whole cavity of the vomer is still seen. called ? Steypirey&r hy the Icelanders. 331 Physalus section are no less strikingly developed. Especiallythe orbital process of the frontal presents exactly the form pe-culiar to this section, being not only very short in the trans-verse direction of the head, but also nearly twice as broad nearits base as along its external border, tapering therefore very muchin an outward direction. The same is the case with the nasalbones, of which a figure nine times diminished is given beneath(fig. 3), though, indeed, in a point of minor importance they Fig. Nasals, appear to deviate a little from those of Balcenojptera antiquo-runij the only species of this section in which they have hithertobeen described and figured with accuracy. They are rathershort, and deeply hollowed on the anterior edge and anteriorpart of their superior surface, so that an obtuse ridge is formedalong the middle line, projecting forwards in a roundish point,as in the species just mentioned; but at the sametimethere is lessdifference in their breadth before and behind than in the hyoid, finally, indicates the same section, as will be seen Fig. 4.
