Berlin, R. Friedländer & Sohn, 1906. Large 4to (33.3 x 27.2 cm). 300 pp.; 34 text engravings, ten lithographed plates, of which one (showing an eel as host species and living animals in situ) in full colour, and some others tinted. Original wrappers with printed text and wood engraving of the Institute' s building in Naples.

Very rare and very beautifully illustrated monograph dealing with a peculiar eel-parasite. Published on behalf of the new Zoological Station in Naples as the second monograph in the series, Fauna und Flora des Golfes von Neapel. The Station was founded by Chun's compatriot Anton Dohrn. "Dohrn's idea was to establish an international scientific community provided with laboratory space, equipment, research material and a library. This was supported and funded by the German Government, Thomas Henry Huxley, Charles Darwin, Francis Balfour and Charles Lyell among others. Dohrn provided a substantial sum himself." (Wikipedia). The large plates are printed by Werner & Winter Lithographische Anstalt in Frankfurt am Main and are of excellent quality. Uncut, thus with the widest possible margins. Rear wrapper spotted. A very good, clean copy with fine, clean plates. Nissen ZBI, 2100.
