Other impressions are those of Anisopus Deweyanus, Brontozoum Sillimanium, Grallator formosus (type of species) and G. cursorius. 66 tracks in all. From Moody Corner, South Hadley. 1854. The original of Plate I. of Ichnology, designed for Frontispiece, and copied upon the salver of a silver service presented to Dr. Hitchcock by the Faculty and students of Amherst College in 1859.
