In the same bed with Ptilograpsus anglicus there occurs abranching fossil, in the same state of preservation as the former,and almost certainly Graptolitic, though I have failed to de-tect cellules except in one instance, and then not with cer-tainty. I possess, however, but a single specimen, which I of the Oenus Ptilograpsus in Britain. 241 owe to the kindness of Mr. Lightbody, of Ludlow. Its modeof branching is much more discrete than that of P. anglicus;and the branches, which arise alternately from opposite sides,are not provided with pinnule or cellules near their true pinnulee are developed on the terminal portionsof the branch
