OF SOUTHERN INDIA. 409 
37. (?) A. Reussii, Orb. (A, elongatus, Rss.) is by no means so very different from the original 
A, elongatus of Sowerby, and most likely identical with it, being a species of Ringinedla. 
A. lineolatus, VOrb. = Phasianella id., Reuss, has been already mentioned in Actgonina. Until 
it has been ascertained that the species possesses a columellar plait, it cannot be correctly transferred 
to the geuus Acton. 
38. 4. Milleri, Bosq. (in Staring’s Bodem van Limburg, II. deel) = J. affinis of Miiller, 
belongs to the sub-generie group Sodidula, having two columellar plaits. 
39-43. A. Doliolum, cylindraceus, bulliformis, acutissimus and coniformis of Miiller from the 
Senonien beds of Aachen are all acknowledged as distinct species by Bosquet (loc. cit.). In none of 
the species have the columellar folds been observed, but except the first, which appears to be a Solidula, 
all the others may be species of Acton or Actaonina. 
44-45. Tornatella Beaumonti and T. Charpentieri, VAxchiac (Bull. Soe. Géol. France; 1854, 
XI, p. 219, pl. 4, figs. 4 and 5), are species of Actaon. 
46. (?) A. granulato-lineatum, Binkhorst (Mong. Gast. et Ceph. 1861, p. 62, pl. 3, figs. 3-4). 
No folds have been observed on the columella, and the species may therefore prove to be an Acteonina, 
and is not improbably identical with Act. acutissimus of Miiller. 
47, A. cinctus, Binkh. (cdidem, 1861, p. 82, pl. 523, fig. 4, non id. Rouill.) may be also an 
Acteonina, resembling our A. obesa. On p. 83, loc. cit., Binkhorst mentions that the species is 
distinct from that described on “page 63, pl. III, fig. 3” under the name of Acton striato-punctata, 
having evidently forgotten that the name applied there is 4. granulato-lineatum ! ! 
48. A. cinctus, Rouill. (Kichw. Leth. ross., 1867, XI, livr., p. 827) is quoted from the “ Neo- 
comien supérieur de Khoroschéwo.” Eichwald mentions that M. Rouillier also figured an Actaon 
elongatus, Rouill., but it appears to be more probably a Natica than an Acteon, Tn the same work 
(p. 826) he mentions 4. Petschore and striatulus, Keyserling, occurring in limestone, which may be 
of Neocomien age. 
49. A. Cenomanensis, Guéranger (Album pal. de la Sarthe, 1867, pl. 91, figs. 16-17) belongs to 
the sub-genus Solidula. ; 
50. <Acte@on inornatus, Guéranger, idid., pl. 13, fig. 31. In his Repert. paléont. the same 
author names a species Act. bullatus, but he does not give a figure of it in the Album. 
51. Tornatella pyrostoma, Seeley (Ann. mag. nat. hist., VII, p. 292, pl. 11, fig. 21), from the 
Cambridge Greensand, only known from a cast, may belong to Solidula. 
52-53.? The Phasianella formosa and striata of Sowerby, in Trans. Geol. Soc., Lond., 2nd 
ser., IV, pl. 18, figs. 14 and 15), have more the appearance of Act@on, than of Phasianella. 
No species have been reported from Africa, but a large number from America. 
54. <A. ornata, VOrb., from Santa Fe. 
55-65. Solidula attenuata, biplicata, bullata,* lenta, Mortoni, Riddelli and subelliptica ; Acteon 
cretaceus, modicellus, ovordeus and texanus ; see Meek’s Check list of cret. foss. of N. America, 1864, 
1 te 
66. A. impressus, Gabb (Pal. Calif. I, p. 142, pl. 21, fig. 106), is, as I have already stated, 
referred by Conrad to a new genus Yornatellea (Check list eocene fossils of N. America, 1866, p. 9), 
but I much suspect that the species is only an imperfect Ringicula. 
67. Tornatellea bella, Conrad (idid., p. 9) is also from the same beds as the last, being con- 
sidered of cretaceous age. 
68. Acteonema prisca, Conrad (ibid.), also from the same beds. 
69-74. I shall note from the South Indian cretaceous deposits the following species, Act, 
(Solidula) semen, Forb., A. (Solidula) pugilis, n. sp., A. seminatus, n. sp., A. turriculatus, D. sp., 
A. curculio, Forb., and A. junceus, n. sp. The other species referred by Forbes and @Orbigny to this 
genus were not correctly determined. 
* Judging from the large size of the shell this could be an Euptycha.
