1848. | SEDGWICK ON THE SKIDDAW SLATE. 223 
Note on the Skiddaw Slate Fossils. 
The specimens, both of Fucoids and Graptolites, are as follows, 
together with the localities in which each is found :— 
Graptolites sagittarius (His. sp.), Scawgill; Knockmurton. 
Graptolites latus (M‘Coy), n. s., Scawgill; Knockmurton, near 
Lamplugh Cross. 
Chondrites informis (M‘Coy), n. s., Whiteless. 
Chondrites acutangulus (M‘Coy), n. s., Low Fell. 
Paleochorda minor (M‘Coy), n. s., Scawgill; Blakefell ; Under 
Crag; Whiteside; Whiteless. 
Paleochorda major (M‘Coy), n. s., Kirk Fell; Under Crag ; 
Whiteless. 
The new species marked above may be described as follows :— 
GRAPTOLITES LATUS (M‘Coy), n.s. 
Spec. Char.—Straight, one edge entire ; the other with small, close, 
conical, very slightly-arched crenulations, touching each other at 
their bases, and scarcely equalling in length half the width of the 
undivided portion of the stem, which is | line wide. 
Compared with the Graptolites sagittarius, G. Ludensis, G. Sedg- 
wickn, G. distans, and the other species with the serrations on one 
side, this is distinguished by the very great width of the smooth, 
undivided portion of the stem, and the comparatively small, close, 
little-curved, saw-like character of the serrations themselves. I had 
previously distinguished the species in the shale of Builth Bridge. 
CHONDRITES INFORMIS (M‘Coy), n. s. 
ad 
Spec. Char.—Frond thick, frequently and irregularly branching at 
short distances; branches short, irregularly elongate fusiform, 
lateral, unequal, about one-third less than the continuous straight
