Graptolithus Sedgwickii, Portlock, Geol. Kep. pi. 19, fig. 1—3; Harkness, Quart. Journ. Geol. Soc. Vol. VII. p. 60. A well-marked species, with curious straight spine-like pro- cesses to the cell mouths. Graptolithus Hisingeri, Carruthers (Geol. Mag. 1868, p. 126). G. Sagittarius, His. not Linn. There seems little doubt that Linnaeus de- scribed under this name a fossil plant instead of a graptolite. The species is excluded from all other strata except the Lower Bala (or Llandeilo flag), and is common therein. Graptolithus lobiferus, McCoy (G. Becki, Bar- rande). A form with the cell-ends so tumid as to give a very pecidiar appearance. (G. millepeda, McCoy, is the young thereof, as suggested by himself.) Graptolithus Nilssoni, Barrande, Grapt. Bo- hdme, pi. 2, figs. 16, 17. Narrow stem, and short cells. Graptolithus tenuis, Portlock, Geol. Rep. Londondy. and Tyrone, p. 319, pi. 19, fig. 7. A narrow thin-stemmed short-celled species. Rastrites (Graptolithus) convolutus, Hisinger, sp. (Leth. Suec. t. 35, fig. 7). Rastrites triangulatus, Salter and Harkness (Quart. Journ. Geol. Soc. Vol. vn. p. 59). Rastrites peregrinus, Barr. may be the young of R. convolutus (Grapt. Bohe"me, pi. 4, fig. 6). Moffat, Dumfries.
