Names and References; Observations, &c. 
Numbers and Localities. 

Rastrites maximus, Carruthers (Geol. Mag. 
1868, p. 126). A species with very large cells. 
Diplograpsus Folium, Hisinger (Leth. Suec. 
t. 35, fig. 8). The double-ranked Graptolites 
were first distinguished by McCoy in 1851 
as Diplograpsus. 
Diplograpsus angustifolius, Hall (Pal. N. Y. 
ul. p. 515). The young states of Diplograp- 
sus have been shewn by Prof. Hall to be 
single trispinous cells. 
Diplograpsus mucronatus, Hall (Pal. N.Y. 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 8, 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. Quebec, p. 111).

laris of Linn. in Skanska Resa, p. 1477.

teretiusculus, Hisinger, Leth. Suec. t. 38, fig. 
4, suppt. Diplograpsus teretiusculus, Salter, 
Quart. Journ. Geol. Soc. Vol. vir. pl. 21,
