170 W. D. Lang — Genotypes of some Polyzoa. 



pi. x, fig. 19 ; genolectotype (here chosen), Cellepora [Bermato- 

 pora) monilifera von Hagenow, 1851, p. 98, pi. xi, fig. 1. 



Discopora, Lamarck, 1816, p. 164; genosyntypes, nine Recent 

 species, of which Gray (1848, p. 126) has chosen Cellepora 

 verrucosa Esper, 1790, p. 239, pi. ii, figs. 1 and 2 (= Tubipora 

 verrucosa Linnaeus, 1758, p. 789) as genolectotype. At the 

 same time, Gray explains that the Cellepora verrucosa of Esper 

 is not the C. verrucosa of Lamarck. Until the identity of Cellepora 

 verrucosa is determined, the interpretation of Biscopora must 

 remain uncertain. 



JJistansescharella, d'Orbigny, 1853, p. 463; genosyntypes, Cellepora 

 familiaris von Hagenow, 1839, p. 274 ; Escharina inflata, Rbnier, 

 1840, p. 14, pi. v, fig. 5; Escharina radiata Reuss, 1846, p. 68, 

 pi. xv, fig. 19; genolectotype, Cellepora familiaris von Hagenow, 

 1839, p. 274; see Lang, 1916, p. 387. 



Eschara, Linnaeus, 1758, p. 804 ; genosyntypes, E. foliacea Linnaeus, 

 1758, p. 804; E.fistulosa Linnseus, 1758, p. 804; E. fragilis 

 Linnaeus, 1758, p. 805 ; E. divaricata Linnaeus, 1758, p. 805 ; 

 E. verticillata Linnaeus, 1758, p. 805 ; genolectotype, E. foliacea, 

 Linnaeus, 1758, p. 804, implicitly chosen by Linnaeus (1761, 

 p. 539), who, in establishing the name Flustra to supplant the 

 name Eschara — "nomen Eschara in Flustram transmutavi, cum 

 prius Morbi homonymon " — mentions three species of Flustra, 

 of which the first two are F. foliacea and F. fstulosa, and the 

 other does not occur among the genosyntypes of Eschara ; 

 again, in 1767, pp. 1300, 1301, he gives six species of Flustra, 

 of which the first, F. foliacea, is the only genosyntype of Eschara ; 

 it seems clear then that E. foliacea was in Linnaeus' mind as 

 typical when Eschara was founded ; besides, F. foliacea is 

 commonly recognized as the genolectotype of Flustra. See also 

 under Flustra. 



Escharella, Gray, 1848, p. 125; genosyntypes, Berenicea immersa 

 Fleming, 1828, p. 533 ; Lepralia violacea Johnston, 1847, p. 325, 

 pi. lvii, fig. 9 ; Lepralia variolosa Johnston, 1 838, p. 278, pi. xxxiv, 

 fig. 4 ; all Recent ; genolectotype, Berenicea immersa Fleming, 

 1828, p. 533, selected by Norman, 1903 2 , p. 117. 



Escharina, Edwards in Lamarck, 1836, pp. 218, 230; genotype, 



E. vulgaris Moll, 1803, p. 55. 



Escharipora, d'Orbigny, 1852, p. 220 ; genosyntypes, seventeen 

 Senonian species, of which E. inornata d'Orbigny, 1851, pi. 686, 

 figs. 17-19, 1852, p. 230, is here chosen as the genolectotype. 



Escharoides, Edwards in Lamarck, 1836, pp. 218, 259; genosyntypes, 

 eleven Recent and eight fossil species, of which Yerrill, 1879, 

 p. 149, selected Cellepora coccinea Abildgaard, 1806, p. 30, 

 pi. cxlvi, figs. 1 and 2, as genolectotype. 



Flustra, Linnaeus, 1761, p. 539; genosyntypes, F. foliacea, Linnaeus, 

 1761, p. 539 (= Eschara foliacea Linnaeus, 1758, p. 804); 



F. fistulosa Linnaeus, 1761, p. 539 (= Eschara fstulosa Linnaeus, 

 1758, p. 804); F.pilosa Linnaeus, 1761, p. 539. In establishing 

 the name Flustra, however, Linnaeus states positively that he is 

 replacing the name Eschara — "nomen Eschara in Flustram
