(State Collection.) ONCOCERAS 3, fig. 3. Reference.—Page, 197, plate 41, 6 and 7, Palaeontology of New-York, vol. 1. This species was described from fragments and the characters werenot completely defined. The specimen figured is almost entirely per-fect, showing the contracted, nearly circular aperture, and the swellingabove, which presents a transversely oval section, suddenly taperingfrom thence towards the apex, which is curved from the commencementof the contraction; surface finely striated, with the striae arching up-ward along the dorsal line. This specimen is almost entire, a small portion of the apex havingbeen broken off only. It is one of the most remarkable forms ofcephalopoda in the lower strata. The specimens figured in the firstvolume of the Palaeontology of New-York, are such as are usuallyfound, the one now described being the only perfect one known to me. From the limestone in the neighborhood of Trenton Falls. PI /
