Important work by Eugène Eudes-Deslongchamps (1830-1889) on the geology of Normandy, where he was born. He was the son of paleontologist Jacques Amand Eudes-Deslongchamps (1794-1867). "Around 1856 he succeeded his father as professor of zoology at the faculty of sciences at the University of Caen, later becoming a professor of geology and dean (1861). After the death of his father in 1867, he devoted himself to the completion of a memoir on the teleosaurs, the joint labours being embodied in his Prodrome des Téléosauriens du Calvados. He contributed several of his memoirs to the Société Linnéenne de Normandie" (Wikipedia). The use of mounted text figures is unusual. The title calls for 47 such text figures, but actually there are 49. Some scattered spotting, mainly on the inner and fore margins of the folded plates; a spot in the title page margin, otherwise very good. Rare. Cat. BM(NH) 2, p. 547. Not in Ward and Carozzi.
