Notes 



fOn p. 27 by Angelin himself amended to Liostracus muticus; by Linnabsson 1877, p. 364, stated to 

 I belong to the genus Ellipsocephalus. 



Compare Lindström 1885, p. 66, and 1907, p. 55. 



I A synonyme is C. Blumenbachi Beongn. — Angelin's figs 5 b — 5d don't belong to this species. Compare 

 J Lindström 1885, p. 63. — As to the hypostoma compare Lindström 1901, pl. 3, fig. 8. 



Not identical with C. tuberculosa Salter. Compare Lindström 1885, p. 66. 



Barrande 1856, p. 23, brought the genus together with Proetus. Schmidt 1907, p. 16, proposed to 



exchange Celmns for Crotahirus Volb. which name, however, is younger. 

 According to Schmidt 1907, p. 15, Crotalurus Barrandet Volb. is synonymous with Celnius granulatus. 



To the genus Centropleura, with C. Lovéiii as genotype, Angelin also referred C. angusticauda, G J 

 dicrœura, C. serrata and C. Steensfrujn (described in the Appendix). Barrande 1856, p. 19, em- 

 phasized that C. Lovéni and C. Steenstrupi ought to be brought together with Paradoxides, a 

 view then shared by Angelin, who, nevertheless, in his left papers, published in the Appendix, 

 maintained the name Centropleura for the two species in question. Later Swedish authors rejected 

 this name or considered the genus Centropleura at most as a subgenus of Paradoxides. Grönwall 

 1902, p. 122, however, rightly looked upon Centropleura as a distinct genus. — As to the other 

 three species, by Angelin referred to C, and for which Barrande, 1. c, proposed provisionally 

 to employ Angelin's generic name, Linnaesson 1869, p. 71, stated that they belong to another 

 family Dicellocephalidœ. 



According to Brögger 1896, p. 21, probably a variety of Apatocephalus serratus. — (The asterisk belonging 



to the number is wanting in the letterpress). 

 On this species as genotype, Brögger 1896, p. 16, based a new genus Dicellocephalina. — Compare Moberg 



and Segerberg 1906, p. 90. 



Angelin originally (p. 2) referred this species to Paradoxides. See the note to Centropleura. — Compare 

 Grünwall 1902, p. 124. 



Brögger 1896, p. 21, took this species as type of the new genus Apatocephalus. — The head was first 

 described by Linnarsson 1869, p. 69, under the name Remopleurides dubius. — Compare Holm 

 1897, p. 465; see also Moberg and Segerberg 1906, p. 88. 



Compare Grönwall 1902, p. 125. 



According to Barrande 1856, p. 21, Angelin later believed this statement to be incorrect and the genus 

 Ceratopyge to appear first in regio BC. Tullberg (Skånes graptoliter I. — Sver. Geolog. Unders. 

 Ser. C. N:o 50, p. 23), however, mentioned Ceratopyge sp. from the Olenus beds and Wallerius 

 (1895, p. 56) Proceratopyge (Ceratopyge) conifrons Wall, from the uppermost Paradoxides beds. 



A subgenus of Phacops; see this. 



f = Chirurus s. s. — ScHMiDT 1881, p. 125, divided the genus Chirnrus Beyr. into the 5 subgenera: Chirurus s. s. 

 1 Cyrtometopus Ang. e. p., Sphœrocoryphe Ang., Pseudosphœrexochus Schmidt and Nieszkowskia Schmidt. 



{Lindström 1885 gave a better copv of Angelin's type specimen. — The tail (plate XLI, fig. 15*) presu. 

 mably does not belong here. (The asterisk of the number 15 is wanting in the letterpress). — Lind- 

 ström in his explanation to fig. 15 (a) of the plate XXXIX, wrongly cites p. 76 instead of 79, which 

 easily leads to confound this species with Sphœrexochus conformis Ang.
