176 Messrs. Parker, Jones, and Brady on 



described by D'Orbigny are true Rotalice. These specimens 

 are from the fossil shell-dust of Sienna and San Quirico.

 figs, rr, ss. D'Orb. op. cit. p. 278. no. 5. 



" Hah. The Adriatic, near Rimini." (Mediterranean, and 

 fossil near Sienna, Soldani.) 



See note on " Model " no. 36, Ann. N. H. ser. 3. vol. xvi. 

 p. 25 ; and Phil. Trans, vol. civ. p. 389. 



86. Truncatiilina tuberculata^ D'Orb. PI. XH. fig. 136. 



"Hammonije tuberculatse " &c. ; Soldani, Testae, vol. i. pt. 1. p. 68, pi. 45. 

 figs. M, kk, lly mm. D'Orb. op. cit. p. 279. no. 1. 



" Hab. Living on the shores of the MediteiTanean and on 

 the European shores of the Atlantic ; fossil at Bordeaux, at 

 Paris, and at Castel-Arquato." 



This is Truncatulina lohatula, W. & J. sp. See note on 

 "Model" no. 37; also Ann. N. H. ser. 3. vol. iv. p. 339, 

 and Phil. Trans, vol. civ. p. 381. 



On Soldani's pi. 41 most of the figures refer to Tr. lobatula ; 

 all but fig. N on pi. 42 ; all on pi. 43 ; most, if not all, on 

 pi. 44 ; all on pi. 45. They are of irregular growth, mostly 

 adherent, and closely embracing. 



87. Truncatulina refidgens., Montfort, sp. PI. XII. fig. 139. 



" Hammonia Balanus seu Balanoiclea ;" Soldani, Testae, vol. i. pt. 1. p. 58, 

 pi. 46. figs. nn[y\ oo. D'Orb. op. cit. p. 279. no. 5. 



" Hab. Adriatic, near Rimini ; Mediterranean, off Corsica ; 

 South Seas, at Rawack, Madagascar, and Cape of Good Hope." 

 (Mediterranean, Soldani.) 



See note on Model no. 77, and particularly Ann. Nat. Hist. 

 ser. 3. vol. vi. p. 340. Montfort's drawing of his " Genre 31" 

 [Cibicides refalgens) is a bad copy of Soldani's fig. oo. 



Both Soldani and D'Orbigny have been misled by the iso- 

 morphism which exists between the two groups Planorhulina 

 (including Truncatulina) and Pulvinulina^ in associating the 

 two figures nn and oo under the same name. It is difficult to 

 speak with certainty from engravings on copper, in a matter 

 requiring nice discrimination with respect to shell-texture and 

 the like ; but we feel assured that the first figure [nn) repre- 

 sents a Pulvinulina — the Rotalina truncaiidinoides of D'Or- 

 bigny (Foram. de Canaries, pi. 2. figs. 25-27), a subvariety 

 of Pulviiiulina Meyiardii, and near P. Michelinianaj P.
