Like many other notable works Palseontologia Scandinavica lias its special 

 history, the summary of which may be given here, in as much as it has influenced 

 the form in which the work appeared. The first fasc. of the work, which is printed 

 in quarto and written in latin, was issued in 1851 ^ with pp. 1 — 24 and plates 

 I — XXIV under the title Palseontologia Svecica. 



The second fasc. containing plates XXV — XLI and pp. 25 — 92 (or rather pp. 

 21—92, because the latter part of the third sheet of fasc, I was reprinted in essen- 

 tially altered form) appeared in 1854, when the title of the work was also altered 

 into Palseontologia Scandinavica, for the evident reason that there are a great num- 

 ber of species from Norway and Bornholm cited in this fasc. Furthermore pp. I 

 — IX were added, containing an account of Silurian stratigraphy, and one page of 

 »Addenda et Corrigenda», besides which plates XX and XXII were exchanged for 

 new ones. 



In 1878 the entire work was reedited by G. Lindström. In this edition there 

 is beside the above-mentioned text and plates a short introduction, in which an 

 account of the history of the work is given. Two new plates, I and XLII, were 

 added and the old plates I — III were exchanged for new and essentially altered 

 ones (la, II and III). All these new plates, with an appendix embracing pp. 93 — 96 

 and containing a description of the species belonging to the genera Paradoxides, 

 Centropleura, and Ogygiocaris, were all among the papers which Angelin left behind. 

 The older rejected plates I — III, XX and XXII were also added, everyone of them, 

 however, being marked: »Ab auctore rejecta» ^. Furthermore, in this edition every 

 plate is followed by an explanation written by G. Lindström. On the title-pages 

 (covers) of the work is given as an under-heading: »Pars I. Iconographia Crustaceorum 

 Forraationis Transitionis», from which appears that fasc. I' and II form only the first 

 part of the projected work. In 1855 Anöelin got a public subvention for editing 

 fasc. Ill ^. This, however, never appeared, but several of the plates intended for this 

 fasc. were printed. Two of these, plates A and B with reproductions exclusively 

 of Crustacea, have probably been appended to privately distributed copies of 

 Palseontologia Scandinavica. Other plates are to be found among the papers which 

 Angelin left behind and which are now in the Swedish State Museum (Natural 

 History) of Stockholm. As some of these plates, spread in some way or other, are 

 mentioned and cited in the literature, it seems to be appropriate here also to devote 

 a few words to these »supplements» to Palseontologia Scandinavica not pubhshed 

 in the ordinary way. 



^ In the T Prœmonenda» of Lindstköm's edition (1878) the first fasc. of Paleeontologia Scandina- 

 vica is stated to have appeared in 1852, which statement the cover of the original edition, however, 

 proves to be false. 



' For the sake of completeness I have also into the following index paid regard to these 

 older plates and to the descriptions given on pages 21—24 of the first fasc, marking the plates and 

 pages in question T, II" . . . and 21', 22* etc.
