Gedani [Gdansk, Dantzig], T. J. Schreiber, 1734. 4to (24.5 x 19.9 cm). Title page in red and black; 78, [i] pp.; with engraved title-vignette and wood-engraved decorated letter N in the praefatio [preface], plus 36 engraved plates. 19th century half cloth over speckled boards, gilt title on spine.

"One of the earliest monographic treatments of the sea-urchins, a major source of information on the Echinoidea for zoologists and paleontologists throughout the 18th century" (DSB). Jacob Theodor Klein (1685-1759) introduced the name Echinodermata, the term now used for the Phylum, in this work (for the class Echinoidea). Title printed in red and black. Several of the figures may be representations of type specimens. Despite the title it does not include true belemnites (fossil Cephalopoda, Mollusca), but there are belemnite-like sea urchin spines. According to some book dealers, the later (1754) French translation has extra plates; that is not quite correct as the total in that work is only 28. However, six of these plates are new and based on specimens from the collection of M. de Reaumur. The other 22 plates are a rearrangement of some figures (not all) from the 36 plates of this first edition (Robert Stokes, in litt.). Plate 31 with a small inoffensive brown spot in the lower part. Otherwise a very good copy with broad margins. DSB VIII, p. 401; Nissen ZBI, 2205.
