the Nomenclature of the Foraminifera. 161 A neat substriate variety, the strige springing from the base of each chamber and extending about three-fourths the way to its summit. 28. Nodosaria {Dentalina) cornicula, D'Orb. PI. IX. fig. 56. " Orthoceras Corniculum ;" Soldani, Testae, vol. i. pt. 2. p. 98, pi. 105. fig. K. D'Orb. op. cit. p. 255. no. 47. " Hob. Fossil, Coroncina." (Mediterranean or Adriatic, Soldani.) This may be accepted as a convenient subvarietal term for a Dentaline N. raphanus [D. ohliqua)^ having a smooth glo-bose primordial segment, larger than those that immediately follow. The later chambers rapidly increase in size ; the last, or tenth, is nearly twenty times as long as the second. 29. Frondicvlaria alata^ D'Orb. PI. X. fig. 66. " Nautili caudiformes ;" Soldani, Testae, vol. ii. p. 13, pi. 1. fig. C. D'Orb. op. cit. p. 256. no. 2. " Hah. The Adriatic." (Fossil near Sienna, Soldani.) A very short wide Frondicidaria ; the lower ends of the chambers irregular and pointed. We doubt the locality given by D'Orbigny for Frondicidaria in a recent state (see Quart. Journ. Geol. Soc. vol. xvi. p. 300). If Frondicularioe, were found by him in the shallow lagoons of the Adriatic, they must have been derived from Tertiary clays. Soldani speaks of this species as common in the fossil state in the clays of San Quirico, Monte Ilco, and the neighbourhood of Sienna. 30. Frondicularia striata^ D'Orb. PI. X. fig. 67. "Orthoceras Cuspisf Soldani, Testae, vol. ii. p. 34, pi. 9. figs. Q, M. D'Orb. op. cit. p. 256. no. 3. " Hab. Fossil at Coroncina." (Near Sienna, Soldani.) A striate variety of the normal form of Frondicularia. (Fig. B is copied.) 31. Frondicularia pupa J D'Orb. PI. X. fig. 64. "Orthoceras Cuspis;" Soldani, Testae, vol. ii. p. 34, pi. 9. fig. S. D'Orb. op. cit. p. 256. no. 4. " Hai. Fossil at Coroncina." (Near Sienna, Soldani.) This appears to be a passage-form between Frondicularia and Lingulina. Such specimens are not uncommon ; and it may be convenient, therefore, to retain the name. Ann. dt Mag. N. Hist. Ser. 4. Vol. viii. 12
