Jena, Gustav Fisher, 1908. Four parts in four. Large 4to (34.3 x 25.5 cm). x, 706 pp. [x, 1-336, 337-706]; 87 mostly chromolithographed plates; two partly coloured maps; 225 text figures. Uniform original "Gustav Fischer orange" wrappers, or black quarter cloth over orange boards, as issued.

This is a very rare, complete set in the original bindings, consisting of the complete "Allgemeiner Teil" [general part], and Spezieller Teil [special part] of the Radiolaria-section, of the results of the first German scientific voyage around the world. The author is the German zoologist Ferdinand Carl Valentin Haecker [or Häcker] (1864-1927) and this may be regarded as his magnum opus. The illustrations are very beautifully done and reminiscent of those of Ernst Haeckel. The full titles are as follows: "Spezieller Teil Erste Lieferung. Aulacanthidae - Concharidae" [text, and plates in two volumes], AND "Spezieller Teil. Die Tripyleen, Collodarien und Mikroradiolarien der Tiefsee" (title; but including the continuation of the Aulacanthidae - Concharidae) AND "Allgemeiner Teil. Form und Formbildung bei den Radiolarien". The first text part includes the plates numbered 63-85. This part seems to be rare in a complete state. In fact, the front wrapper has a stamped text in the top margin, stating "Ohne Tafelerklarung 63-78", but all explanatory leaves are present. Some spines ends slightly abraded, one back wrapper with a small piece of paper missing and some creasing to wrappers. Most parts bumped (or partly) into the upper inner corner, one also to the lower inner corner and one with some creases to the bottom part of the pages and plates. Otherwise, a very good, complete and clean set. Cat. BM(NH) Supplement, p. 423; Nissen ZBI 1789, 4625.
