London, Palaeontographical Society, 1886-1896. Nine parts in one. 4to (27.5 x 21.4 cm). General title, titles to the years (different for each part), and for the parts; 514 pp.; 44 lithographed plates with explanatory text leaves. Later brown buckram. Spine with dark brown morocco label with gilt lines and title.

A fine, clean copy of this very important contribution to the well-preserved mid-Jurassic faunas of England. The illustrations are excellent. Many species are described as new by the British palaeontologist, malacologist, ornithologist, and president of the Geological Society of London, Wilfred Hudleston Hudleston (1828-1909). His birthname was Wilfred Simpson. He acquired the surname Hudleston, of Hutton John, Cumberland, later. This is his magnum opus, which was published over a long period, and seldom found complete. All individual parts are uncommon to rare. A complete, well-bound set, such as this one, is definitely very rare. Cat. BM(NH) p. 885.
