POKITID.-E. 9 



3. Astmomm-pha Reuss (Wiener Denksch., vii. (1854) p. 127). See Duncan's Revision, p. 135. 



4. Cocmseris Eichwald (Lethfea Rossica, i. pt. 1 (1860) p. 442). Placed by Lindstrbm among 



the Heliolithida;, Kong. Svenska Vetens.-Akad. Handlingar, xxxii. (1899-1900) p. 189. 



5. Canostronm. Winchell (Proc. American Assoc, 1866). On this genus also see Lindstrom, 



ix. pt. 2 (1870) p. 6 of the same publication. 



6. Coscinarma M.-E. & H. (C.R., xxvii. (1848) p. 496). Placed by Dr. Klunzinger among the 



Fungidse, Cor. des rothen Meeres, iii. (1879) p. 78; see also Duncan's Revision, cited 

 above. 



7. Cos7noporite$ Duch. and Mich. (Les Cor. des Antilles, supp. (1864) p. 99). Not sufficiently 



distinguished from Pontes. 



8. Dichorcea Woods (Linn. Soc. New S. Wales, iii. (1879) p. 96, pi. x. fig. 4). This minute 



coral appears to me to be allied to the Favositidse. 



9. Dicli/ara'a Reuss (Novara Expedition, vol. ii. (1866) p. 17-5). On this genus see the remarks 



made on p. 30. 



10. Dictijophyllia de Blainville (Diet. Sci. Nat., Ix. (1820) p. 325) = Mcmrdrina reticulata 



Goldfuss, pi. xxi. fig. 5 ; cf . also the figure of Ckistopora in Nicholson's ' Manual of 

 Paleontology,' i. (1889) p. 310. See also Duncan's Revision, p. 131. 



11. Dimm-plMraa Fromentel (' Introduction a I'etude des polypiers fossiles,' 1861, p. 254.) This, 



according to Duncan, is a Microsolenid (see his Revision, p. 170). 



12. Heptastylk Freeh. (Pateontographica, xxxvii. p. 18). The resemblance of this to the 



Poritidae is purely superficial. 



13. Holarcea M.-E. & H. (C.R., xxix. 1849, p. 259). Subsequently merged with Axapora, in 



'LesCoralliaires,'iii. (1860). 



14. MwaTidrarcea Etallon (Lethsea Bruntrutana, 407, pi. 57, pp. 11 and 12). There is not 



sufficient evidence to connect this with the Poritidse. 



15. Microsolena Lamouroux (Exp. Method (1821) p. 65). The long septa running from calicle 



to calicle in curved lines is not a character of the Poritidse. 



16. Napopora Quelch (Ann. Mag. Nat. Hist., xiii. (1884) p. 296). Merged with Porites in 



Vol. V. of this Catalogue. 



17. Neoporites Duch. and Mich. (Cor. des Antilles, supp. (1864) p. 97. Merged with Porites. 



18. Palmoporites Kiar. (Palsontographica, xlvi.). The name of this new genus seems to 



suggest a phylogenetic connection with the recent Poritidse ; but if it is a Heliolithid 

 it could not be related to any member of the true Perforata. 



19. Pleurodidyum Goldf. (Petref. Germ., i. (1829) p. 113) is a Favositid. 



20. Protarma M.-E. & H. (Pol. foss. Terr. Pal. (1851) p. 208). See Lindstrom's Heliolithidaj 



(cited above). 



21. Psammomra Dana (Zooph. (1848) p. 344). See Duncan's Revision ; also Dr. Klunzinger's 



work above quoted. 



22. Rhodarcea M.-E. & H. (C.R., xxix. (1849) p. 259). Merged with Goniopora (see this volume 



23. Somplwphm-a Lindstrom (Richthofen's China, iv. (1883) p. 51) is a Favositid. 



24. Stylara-a Seebach (Zeitsch. Deutsch. Geol. Ges., xviii. (1866) p. 306) is the same as Coccoseris 



Cp. Lindstrom (I.e.). 



25. Stylaroea M.-E. & H. (Klunzinger, Kor. des Rothenmeeres, ii. (1879) p. 43. Merged in this 



Catalogue with Porites (Vol. V. in preparation). 



26. Synarmi Verrill (Bull. Mus. Comp. Zool. Camb. Mass., 1864, 3, p. 42). Merged in this 



Catalogue with Porites. 



27. Thecia M.-E. & H. (C.R., xxix. (1849) p. 263). According to Miss Ogilvie (Phil. Trans., 



clxxxvii. p. 339) allied with Protarma, Coccoseris, etc. 



28. Tichopora Quelch (Chall. Rep., -xvi. (1886) p. 188). Here merged with Goniapora (see p. 16).
