Show 648 Dn. J. MURIE ON RHINOCHETUS JUBATUS. [Nov. 7, terminology*. On looking over m y article as printed, it seems to m e a useful purpose would be served by the addition of a note showing the precise equivalents of the respective areas treated of by the above German authority and myself. The subjoined tabular view of the nomenclature of Nitzsch and myself shows at a glance the relation of terms employed in distinguishing the several portions of the contour, feather-tracts, featherless interspaces, and powder-down patches. Tract has beeu employed by Nitzsch for the lines of feathering, as shown in the first column ; space for the bare portions, column two ; and by simply using patch (column three to the right) I define where the powder-downs are found. The minor terms differ, but their import is easily understood. The blanks indicate portions wanting in one but present in the other, or where no subdivision has been recorded.
