A fine, clean copy of the very rare "deluxe" hand-coloured and India ink "double suite" edition (only 25 copies were made) with excellent clean plates in double state: on tinted paper, and hand-coloured. Very nicely bound with the original wrappers bound in. This is series I (28): Marine Mollusca. Pediculariidae, Ovulidae, Doliidae, Cassididae. The first two families have five plates; the Doliidae and Cassididae (now: Tonnidae, Ficidae, and Cassidae) occupy sixteen plates. The genera Pachybathron and Morum (Cystiscidae, resp. Harpidae), once thought to be cassids, are included as well. Stamp on two text pages, otherwise a very good, clean copy. Nissen ZBI, 4176.
