AB - 8 DR. W. BAIRD ON A NEW BRITISH ANNELIDE. that the singular bony enlargements on the posterior face of the sternum and in the bumps or knobs at the sternal edge, as seen in the drawing sent, mark the ultimate development of the trachea; whilst the state of the trachea in the sternum sent by Sir John Richardson to Mr. Yarrell, and which I now assign to C. Pass- mort, may be a less advanced form of the same structure, and those I have since examined may be still younger forms of the same species. Tt may be, indeed, that the specimens since examined are younger specimens of OC. Passmori, and that the true C. buccinator is less common, or at least a more northern form ; but I think it right to indicate the doubt which I feel myself respecting the new species, leaving the facts for the consideration of better judges. I thought I followed excellent authority in considering such a difference in the trachea as a sufficient mark of a distinct species; but the facts will not be less interesting to ornitholo- gists if they see reason for using such characters with greater caution in future.
