286 CRETACEOUS PELECYPODA 



66. — A, difficilis lias a very characteristie name,, for all we know of it is that it is ^^round/^ 



67_58. — A. similis'^ and laticostata are species of Gouldia, 



69. — A. Gumhelii. 



70-74. — A. acuta, nana, porrecta, ccBlata\ and RoemeriX are apparently Gouldm, 



7b.— A, Benedeni, Miiller, (Pet. Aach. Kreidef. Suppl., 1859, p. 11, pi. 7, %. 12) ; this may 

 be a species of Fleuromeris, or Oyclocardia, but it does not agree with Astarte, 



76. — A. Miqueli, Miiller, (ihid. p. 12, pi. 7, %. 13,) strongly recalls the form of an Mripliyla. 



11. — A. circularise Gueranger, (Album pal. de la Sarthe, 1867, pi. 15, fig. 12, and pi. 16, 

 figs. 7^8). 



78.—-^. Mosquensis, d'Orb., (Eichwald, Leth. ross., x livr., p. 621,) is considered a neoco- 

 mien species and is most probably an Eriphyla. 



19.— A, borealis, d'Orb., non Nilson, (Eichwald, ibid. p. 622). The change of the 

 specific name may be deferred until the generic character of this species has been fully 

 ascertained. 



80-81. — A. Veneris and ovoides, Buch, Eichwald, ibid. pp. 625 and 628. 



82.>83.— ^. porrecta, Buch^ and suh-ohtusa, d'Orb., Eichwald, ibid. pp. 629 and 630, from 

 the Neocomien of Russia. 



84-89, — A. lurida, dimidiata, gravida, princeps amygdala^ and triangularis (non idem Mont. 

 a recent species,) are described by Coquand from the Aptien of Spain (Monog. de Tetao-e 

 Aptien, &e., 1865, p. 122, &c.). None of the species are very characteristic forms as compared 

 with typical Astarte, but as neither the hinge-teeth nor the internal characters of the shells are 

 pointed out, it seems useless to suggest any alterations in the generic names. 



9^-91.-^Astarte mantica, Loriol, (Pal. Suisse, 4^^ gg^^^ Monog. de Fetage Valangien, &c., 

 1868, p. 29,) is to all appearance a true Frmconia, and to the same most probably also belongs 

 Cardita cuUrigera, Loriol, (ibid. p. 30). 



92-99.-4. cardiniformis, amygdala (non idem Coq., 1865,) lacryma, saharensis, AdJierhalesis, 

 Ga,i(B, punica, and Delettrei are noticed by Coquand from the Province Constantino (Geol and 

 Pal. Const., 1862, pp. 196-197). 



\{){),^Ast. Herzogii, Krauss, (Nov. Acta Acad. Leop. Carol., xxii, pi. ii^ pp. 447^ &c.) from 

 the so-called lower cretaceous ( ? Jurassic) beds of South Africa, is a Grotriania, 



Ast. Bronni, Krauss, ibid p. 449, is most probably a Bemondia (see further on familv 

 Trigoniid^.) ' ^ 



101-107.--4. crenulata, gregaria, lineolata, octolirata, pasilis, Texana and WasJiitaensis are 

 quoted from North America in Meek^s Check-list of cretaceous fossils (Smiths Misc roll 

 No. 177, 1864, p. 11). , * • ' 



108-110.— J. Conradiana, Mathewsonii, and Tuscana are from California (Pal Cal'f * 

 pp. 178-179). ' ^''^' 



111.— 4. duhia, d'Orb., Voy. Am. merid., tom 3"^% 1842, p. 105. 



112-113.— 4. truncata, Buch, (ibid p. 25), and ^. ^^^^^'^^^ d^ Orb., (ibid. p. 83) ; the last is 

 either a Pjmconia or a Caryatis. 



114-124.-From PalaBstine Conrad described in Off. Rep. of Lynch's exped. A. mncronata 

 undulosa, Incmoides, sui-cordata, St/riaca, orientalis, ptrvehis, engonata (?), arctata. I only knovv 

 these names from Fraas' reference iu Wiirt. Natur. Jahresh., xsiii, 1867, p. 334; he' says that thi 

 last seven names are based upon undeterminable casts. A. t^fiMom he helkJs to he A . formosa, 



Galil.^'"' ^^°"' ^°''-^'^"^^''^' IS*^^' P-115,) identifies with this species A. sul-c^p^UateralU, Alth, from 

 t See Gouldia pi anissima, Forbes, p. 289.
