V8 Transactions of tlie Sociefij. 



It will be observed that some of the sulj-geiicra in tlie text of the 

 " Tableau " do not appear iu the Table, but became genera in iiis later 

 Tables. Some of these, e.g. Mucrouina, Discorbina, Trochulina, 

 Turbinuliua, and Saracenaria, never appeared again as genera. In the 

 headings to his genera in the Cuba and Vienna Memoirs Mucronina is 

 absorbed into Nodosaria, Turbinulina into Eosalina, and Saracenaria 

 into Cristellaria. Discorbina {Bmorhis Lam.) was revived by Carpenter, 

 Parker and Jones in 1862 (XVtI., p. 11)9). TrochuUna disappeared 

 altogether. 



Notes to Appendix F. 



(1) The genera Ooliua and Bolivina do not appear in the Cuba Memoir, but 

 made their first appearance iu the South Anaerica Memoir, published in the same 

 year and innnediately after it. All the other South American genera and all the 

 Canary Island genera appear in the Cuba IMemoir, in which he establishes genera 

 for many species known to him from other localities but not found in the Cuba 

 material. 



(2) It will be observed that with the exception of Amphorina, a genus introduced 

 here for the reception of Lagenidae furnished with a more or less pronounced neck, 

 the 1S46 and 1844-5 Tables are identical. He never figured any Amphorina as 

 such, but it is to be presumed that he would have transferred to the genus such 

 species as Oolina (L) clavata, striata, and striaticoUis. The geaus was only 

 adopted extensively by Seguenza (" Poraminiferi Monotalamici mioceniche di 

 1862), and twice (A. elongata and .4. gracilis) by Costa. 



(3) No attempt has been made to preserve any d'Orbignyan sequence of genera 

 alter 1826, as their order varies more or less iu each Table. 



(4) d'Orhigny did not adopt the Latinized termination ina until 1839. In 1826 

 the terminatioii is invariably French: — Nodosaire, Liuguline, Frondiculaire, 

 Kimuline, etc. 



(5) Included as a synonpn of Vaginuliua in 1846. The genus was only used 

 (for single species) subsequently by von Romer, Schwager, and Reuss. 



(6) = Lageua. 



(7) = Cristellaria. (8) = Rhabdogonium. 

 (9) = Bigeuerina (pars), Bolivina (pars). 



(10) Removed (erroneously) in 1839 to " Agathistegues.'' 



(11) = Polymorphina. 



(12) In the text of the "Tableau" Gemmuliua appears as a subgenus of 

 Bigenerina. 



(13) After 1826 d'Orbigny placed the " Nautiloides " before the " Turbinoides," 

 and suppressed his second division, the " Ammonoides." 



(14) - Globigerina (pars), Cymbalopora (pars), Discorbina (pars), Rotalia 

 (pars), etc. 



(15) = Pulvinulina (pars), Rotalia (pars). 



(16) = Polymorphina. See note (41) below. 



(17) Occurs in the Table on p. 30 of the Cuba Memoir, but not in the text or 

 in any other Memoirs. It is apparently the same as Ghrysalidina. See the note 

 on this genus in Sherborn's Index. 



(18) = Anomalina. 



(19) Removed in 1839 to the class " Turbinoides." 



(20) Removed in 1839 to the class "Nautiloides." 



(21) = Cornuspira (pars), Cristellaria (pars), Planorbuliua (pars). This genus 

 disappeared after 1826, being apparently a kind of refuge-genus instituted by 

 d'Orbigny for several species from Soldani's " Testaceographia," which he found 

 himself rinable to place (see p. 27). They have been discussed with some care by 

 Parker and Jones. See XX., pp. 178-9, 238. 



(22) Removed in 1839 to " Entomostegues." 



(23) Removed in 1839 to the class " Turbinoides." 



(24) = Peneroplis. (25) = Cristellaria. 



(26) D'Orbigny observes in a note in 1826(1., p. 295) that "Living species
