Index to N. P. Angelin's Palseontologia Scandinavica, with notes 21 



Note 



On p. 27 by ANGELIN himself amended to Liostracus muticus; by LINNARSSON 1877, p. 364, stated to 



belong to the genus Ellipsocephalus . 

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

 A synonyme is C. Blumenbachi BRONGN. ANGELIN'S figs 5 b5 d don't belong to this species. Compare 



LINDSTROM 1885, p. 63. As to the hypostoma compare LINDSTROM 1901, pi. 3, fig. 8. 

 Not identical with C. tuberculosa SALTER. Compare LINDSTROM 1885, p. 66. 



BARRANDE 1856, p. 23, brought the genus together with Proetus. SCHMIDT 1907, p. 16, proposed to 



exchange Celmns for Crotalurus VOLB. which name, however, is younger. 

 According to SCHMIDT 1907, p. 15, Crotalurus Barrandei VOLB. is synonymous with Celmus granulatus. 



To the genus Centropleura, with C. Loveni as genotype, ANGKLIN also referred G. angusticauda, C.? 

 dicrceura, C. serrata and C. Steenstrupi (described in the Appendix). BARRANDE 1856, p. 19, em- 

 phasized that C. Loveni 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. G RON WALL 

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

 three species, by ANGELIN referred to G., and for which BARRANDE, 1. c., proposed provisionally 

 to employ ANGELIN'S generic name, LINNARSSON 1869, p. 71, stated that they belong to another 

 family Dicellocephalidce. 



According to BROGGER 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, BROGGER 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 

 GRONWALL 1902, p. 124. 



BROGGER 1896, p. 21, took this species as type of the new genus Apafocephalus. 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 GRONWALL 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 (Skanes 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. 



!= Chirurus s. s. SCHMIDT 1881, p. 125, divided the genus Chirurus BEYR. into the 5 subgenera: Chirurus s. s. 

 Cyrtometopus ANG. e. p., Sph&rocoryphe ANG., Pseudosphcerexochus SCHMIDT and Nieszkowskia SCHMIDT. 

 ! LINDSTROM 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- 

 STROM 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 Sphcerexochus conformis ANG.
