1862. 7 p., 1 lithographed plate and several white sheets, contemporary half calf with gilt title on spine, marbled flyleaves. Published in: Journal de Conchyliologie Scarce monograph, with one new species of Scissurellidae from the Paris Bassin Eocene. Written by Charles Philippe Ernest Munier Chalmas (1843-1903), who also had a species of Scissurella named after him. The paper was published at a time, apparently, when the Journal de Conchyliologie was issued in very low numbers. A very scarce offprint of the volume X issue of October 1862, pp. 391-397, and pl. XVI. A very good, nicely bound copy.
