 1819. Aladreporites interstinctus, Wahlenberg. Petref. Svec, p. 98. A short descriptiou intended to embrace 



the Linnean form. 

 1828. Astrasa stelliilata, His. Anteckn. IV, p. 241. 



1831. Astrtea interstincta, ID. p. p. Anteckn. V, p. 127 and Esquisse, p. 26. Tlie coUections of HiSINGER 



preserved iu the State Museum of Natural Hist. at Stockholm contain under the 

 varying uames of Astrasa porösa and Ästréea interstincta a nuniber of differeiit 

 Heliolitidae. 



1838. Astrasa porösa, ANGELIN. Mus. Palaeont. Svecicum, N:o 5. 



1839. Porites pyriformis, LONSDALE. Sil. Syst., p. 686, pl. 16, fig. 2c, 2rf, 2e. Figs. 2«, 2Ä belong scarcely 



to the same species, possibly it is a variety with small calicles. 

 1841. Astrasa porösa, HiSINGER. Förteckning, p. 58. 



1845. Porites. pyriformis, LONSD. in Murchison Russia, vol. I, p. 626. 



1846. Porites interstincta, Keyserling. Beobacht. auf eiuer Reise iu Petschora Land, p. 175. 

 1851. Palaeopora interstincta, M'COY. Brit. Palieoz. Fossils, p. 15. 



1851. Paliieopora '? favosa, M'COY p. p. Ibid. p. 15. This species is evidently coraposed of iucongruous 



elements and, araongst the figures on pl. IC, the fig. 35 entirely ooincides with the 

 Gotland specimens. 



1851. Heliolites subrotnndus, Salter, in MURCHISON Silurian Rocks of Scotland, Qu. Journ. Geol. Soc. vol. 7, 



p. 171 and also p. 144, pl. IX, f. 9. It is possible that this may he identical 

 with this species, but there is no description, and the figure of a cast leaves the 

 identity undecided. It might as well be an impression of a Coccoseris. Salter 

 adopted the species name »subrotundus» from the second word of the description 

 in Cor. Balt., erroneously attributing it to FOUGT. 



1852. Heliolites macrostylis, HALL. Pal. N. York II, p. 133, pl. 36^, fig. 2a is probably identical with this 



species, not Hel. pyriformis HåLL. 



1854? Heliolites interstincta, Edw. H. p. p. Brit. Poss. Cor. p. 249, pl. 57, fig. 5Zi. This fig. is the only 



one of all given that can he identified with ours. The descriptions given in the 

 various works of these authors are not so consistent which eaeh other that they 

 can be regarded as aiming at the same species. In Polyp, palaeoz. there is given 

 as a character »douze cloisons assez bien développées», in Brit. Foss. Cor. again 

 the figure cited above shows short equal sized septa. 



1854. Heliolites interstinctus, SALTER iu Siluria, l:st ed. p. 120, f. 3, 4, 5, pl. 39, f. 2 — ie. Fig. 3 ealled 



Hel. megastoma. The same figs. recur in the låter editions of Siluria. 



1856 — 57. Heliolites porösa, Haughton. Geol. Notes & Illustrations, Appendix to M'Clintock, Reminiscenses 



of Antaretic Ice Travel in Journ. R. Dublin Soc. vol. I, p. 183, pl. X, Hg. 5, 

 5a, bad figures and incomplete description. Worn specimen, but probably of this 

 species. 



1862. Porites megastoma, M'COY. Sil. foss. of Ireland p. 62, pl. IV, f. 19. The MS of this work was finished 



already in 1846, bnt was not printed before 1862. In Biitish Pal. Foss. p. 16, 

 the first part of which was printed 1851, he refers to this work, when describing 

 a dififerent coral, beins a Coccoseris, with the same deuomination.
