The young states of Diplograp- sus have been shewn by Prof. Hall to be single trispinous cells. Diplograpsus mucronatus, Hall (Pal. Vol. I. p. 268, t. 73, fig. 1). Diplograpsus pristis, Hisinger? (Leth. Suec. p. 114, t. 35, fig. 5. Fucoides dentatus, Brong. Grapt. foliaceus, Beck. Sil. Syst.). One of the numerous varieties or species referred to this almost cosmopolitan form. Mr. Car- ruthers figures it with long thread-like radi- cles, and believes this to be the true species of Hisinger. Diplograpsus pristis ft McCoy. A variety fi- gured by Prof. Hall; with broader and more triangular teeth. Diplograpsus persculptus, Salter MSS. (Carru- thers, Geol. Mag. 1868, p. 130). A beautiful undescribed form, very distinct in its sculp- ture from D. pristis. Climacograpsus, Hall, cells in double row, but excavated, not projecting. The stem cylin- drical (Grapt.
