DESCRIPTION OF NEW SPECIES OF FOSSILS AND REMARKS 



ON SOME OTHERS, FROM THE LOWER AND UPPER 



SILURIAN ROCKS OF OHIO, BY U. P. JAMES. 



GENUS SACCOPHYCUS, (gen. nov) (James) 



[Saikos, a bag or sack. — Phykos, a sea plant.) 



This Genus consists of a sack-like plant; even or undulating surface, 

 smooth, or striated longitudinally; straight or contorted; sides and ends 

 rounded and drawn in and under. 



Saecophycus intortUS- (sp. nov.) (James.) {intortus — twisted inward.) 



Sphenothallus latifolius ? Hall. Pal. No. 2. Oct. 14, 1878. 



This species, described and published as above stated, was referred, pro- 

 visionally, to *S'. lad/olius. On further examination it seems clear that it does 

 not belong to that genus, and cannot be sp. latifolius for reasons given. 



Saecophycus intortus is in the form of a long, tortuous bag or sack, with the 

 ends drawn in; undulating, wavy surface, finely striated longitudinally; sides 

 and ends rounded in and under. 



The specimen here described is about three inches in length and one inch 

 broad from the center to near one end, but it narrows to about half an inch 

 near the other end ; thickness unknown as it lies on and partly imbedded in a 

 fragment of limestone, but it seems to be about a quarter of an inch. 



Position and Locality — Lower Silurian, Cincinnati Group, near Lebanon, 

 O. Found by Mr J. G. Shepard. 



GENUS LOCKEIA, (genus nov.) (James.) 

 Genus consisting of elongated, convex fossil sea-plants, rounding and 

 tapering to sharp or obtuse points, seed-like in appearance, with or without 

 sliglit longitudinal depressions, attached to the surface of rocks. 

 Named in honor of the late Professor John Locke of Cincinnati 



IiOCkeia Siliquaria. (sp. nov.) (James.) (^siliqtiaria — pod-like.) 



This species consists of convex, elongated elevations on the surface of in- 

 durated clay, or limestone, from V^ to ^ an inch long. ^ a line to i ^4 lines 

 broad at the base, and y^, a line to i line high in the center ; sloping and 

 tapering to sharp, or more or less obtuse points at each end, and either rounded 

 or rather sharply ridged longitudinally, and scattered about promiscuously 

 (seemingly) at every possible angle with eacji other ; sometimes arranged in 

 the form of stars — one in the center and five others placed quite regularly 

 around it with their longer axes pointing inward ; in some other cases they 

 are in groups close together, or lying one partly over the other ; others are 

 half an inch or more apart 



Slabs are found from an inch to one or two feet or more, either way with 

 one surface covered with this fossil in the manner stated, which are sometimes 

 likened to grains of wheat. It is of common occurrence on the bank of the 

 Ohio River, in Ky , opposite the lower part of Cincinnati, about half way 

 between low and high water mark, but not found at any other horizon that I 

 know of. Lower Silurian, Cincinnati Group.
