London, The Zoological Society of London, 1881. 4to (32.0 x 25.5 cm). 40 pp.; some text figures, 13 lithographed plates (three finely hand-coloured). Original printed wrappers.

Published in the Society's Transactions 39 (!) years after "Part I". This is one of Richard Owen's major malacological publications. It deals with Dibranchiata (genus Tritaxeopus), Plectoteuthis grandis, etc. Three of the fine lithographic plates (by J. Erxleben) are beautifully hand-coloured, the other plates are mostly by the famous Anglo-Dutch natural history illustrator Joseph Smit. Wrappers chipped at edges, the rear wrapper more affected, with some longer creases and a long tear, the spine cover much abraded; internally, however, much better: offsetting from the first plate to the opposite text leaf, otherwise an excellent, clean copy. Uncommon. Caprotti II, p. 208.
