Fatka, Oldřich, Knížek, František & Kozák, Vladislav, 2015, Condylopyge Hawle Et Corda, 1847 In The Příbram-Jince Basin (Barrandian Area, The Czech Republic, Agnostida), Acta Musei Nationalis Pragae Series B 71 (1 - 2), pp. 103-109 : 105-106

Genus Condylopyge HAWLE et CORDA, 1847

T y p e s p e c i e s: Battus rex BARRANDE, 1846, p. 17 ; middle Cambrian, Drumian, Paradoxides (Eccaparadoxides) pusillus Zone, Buchava Formation, Skryje-Týřovice Basin, Barrandian area, the Czech Republic.

D i a g n o s i s. See Shergold and Laurie (1997, p. 383).

D i s c u s s i o n. The type species was briefly described by Barrande (1846, p. 17) as Battus Rex. In the following year, Hawle and Corda (1847, p. 50, tab. 3, fig. 24) provided a German diagnosis of their new genus Condylopyge , which was based on morphology of the only one known specimen.

At the end of the 19 th century, three other species and one subspecies were described, namely Agnostus cambriensis HICKS, 1871 ; Agnostus regius SJÖGREN, 1872 ; Agnostus regulus MATTHEW, 1886 and Agnostus rex var. transectus MATTHEW, 1896 .

The study by Hawle and Corda (1847) was repeatedly cited by Jaekel (1909, p. 380), but this author did not mention the genus Condylopyge and surprisingly established a new genus Paragnostus with type species Agnostus rex . This approach was rejected by Raymond (1913, p. 138) and all subsequent authors with the argument that the same species is the type of Condylopyge HAWLE et CORDA, 1847 . Condylopyge was briefly discussed by Kobayashi (1939, p. 107, table), who listed six species and two subspecies, all ranging from the early to mid middle Cambrian. Shergold et al. (1990, p. 57) and Shergold and Laurie (1997, p. 383) give the stratigraphic range of Condylopyge from the Protolenus Zone of Avalonia to the Ptychagnostus punctuosus Zone of Baltica.
