Index to N. P. Angelin's Palteontologia Scandinavica, with notes

Plate A \ containing 36 numbers most of them with several figures, all of 

 which represent Ostracoda (and according to the present view possibly also Phyllo- 

 carida), is mentioned in several passages by Barrande in his Système silurien etc. 

 Suppl. au Vol. I. — On p. 485 Barrande gives the name Beyriehia Angelini to 

 figure 36 of plate A, and on p. 519 we are told that Leperditia haltica His. and L. 

 primordialis (described in 1869 by Linnarsson) are reproduced on the same plate. 

 According to Moberg and Gronwall ^, the figures 16 and 17 represent Klœdenia 

 Kiesotvi Krause. As for plate B, which has 6 reproductions of Merostomata and 

 Phyllocarida, Barrande mentions (1. c. p. 438) that this plate represents fragments 

 of Ceratiocaris, originating from Gotland, of which one with 7 or 8 free segments ^. 

 Gronwall * speaks of a table XLIII, on which Paradoxides Davidis Salter is 

 reproduced under the name >•> Paradoxides Pingelii Beck M. S.» 



Moreover at this place it is to be pointed out, that before Angelin set to work 

 writing Paleeoutologia Scandinavica, he had already brought together and sold col- 

 lections of Swedish fossils, several of which he had himself named. A list of 

 these collections, embracing five decades, was printed under the title »N. P. Angehni 

 Museum palaeontologicum suecicum. Sectio prima. Petrefacta formationis s. d. trans- 

 itionis superioris, centuria l:ma» as an off-print from Naturhistorisk Tidskrift udg. 

 af H. Kröter, Bd 2, Köbenhavn 1838 — 1839. When Angelin in Palseontologia 

 Scandinavica cites one of these new species, viz. Cyphaspis (Prœtus, Goniopleuraj 

 elegantula, he puts »nob.» after the name and not, as is usually the case when he 

 is speaking of previously undescribed species, »n. sp. » 



The great importance that must be attached to Angelin's Palteoutologia Scan- 

 dinavica does not, however, consist only in the considerable number of new 

 trilobite species, which are described and reproduced in it, but also and perhaps not 

 least in his stratigraphical scheme for the Silurian of Sweden, which was given in 

 the introduction of the second fasc. of the work. As this scheme, in which the 

 Silurian of Sweden are divided in 8 vertical »regiones», has been of fundamental 

 importance for the exact establishment of the sequence of the Swedish Silurian, it 

 will seem justified here to call attention to some of its details which are illustrat- 

 ive of the genesis of the scheme. After giving three profiles taken from the Vestro- 



' To judge from Baeeande's statements (Système silurien etc. Suppl. au Vol. I, pp. 485 and 

 520) it will seem that tab. A exists in two somewhat different editions, of which one has been 

 appended to copies of fasc. II, distributed in 1854, the other «avec diverses modifications dans 

 les figures» has been distributed in i860, >dans la cJ™'' livraison de cet ouvrage» (Pal. Scand.). That 

 the text of fasc. II has in some slight degree been altered is evident from the fact that at least 

 the pages III — IV, as well as the leaf containing Addenda et Corrigenda, and the pages 25 — 28 and 

 65 — 66 exist in two somewhat different editions. By citing the rejected pages, I always mark them 

 6. g. 26', 65^ a. s. o.
