286 CRETACEOUS PELECYPODA 



GG.—A. cUfficilis lias a very characteristic name, for all we kaow of it is that it is " round." 



67.68. A. similis* and laticostata are species of Gouldia. 



60. — A. Giimbelii. 



70-71..—^. acuta, nana, porrecta, ceelataf and RremeriX are apparently Gouldia. 

 n.—A.Benedeni, Muller, (Pet. Aach. Kreidef. Suppl., 185'J, p. 11, pi. 7, fig. 12) ; this may 

 be a species of Pleuromcris, or Cijdocardla, hut it docs not agree witli Astarte. 



7Q.—A. Miqueli, MiiUer, (ibid. p. 12, pi. 7, fig. 13,) strongly recalls the form of an Eriphyla. 

 77.— A. circularis, Gueranger, (Alhum pal. de la Sarthe, 18G7, pi. 15, fig. 12, and pi. 16, 



figs. 7-8). 



78.—^. Mosquensis, d'Orh., (Eiehwald, Leth. ross., x livr., p. G21,) is considered a ueoco- 



raien species and is most probably an Eriplnjla. 



7d.—A. borealis, d^Orb., non Nilson, (Eiehwald, ibid. p. 622). The change of the 

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



ascertained. 



80. SI. — A. Veneris and ovoides, Buch, Eiehwald, ibid. pp. 625 and 628. 



82-S3.—A. porrecta, Buch, and sub-obtiisa, d'Orb., Eiehwald, ibid. pp. 629 and 630, from 



the Neocomien of Russia. 



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

 a recent species,) are described by Coquand from the Aptien of Spain (Monog. dc I'etage 

 Aptien, &e., 1865, p. 122, &e.). 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. 



<i)Q-<dl.— Astarte mantica, Loriol, (Pal. Suisse, 4'°» ser., Monog. de I'etage Valangien, &c., 

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

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



92-99.—^. cardiniformis, amygdala (non idem Coq., 1865,) lacryma, saharensis, Adherhalesis, 

 Gahce, pimica, and Beleltrei are noticed by Coquand from the Province Constantine (Geol. and 

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



100. Ast. Ilerzogii, Krauss, (Nov. Acta Acad. Leop. Carol., xxii, pi. ii, pp. 4'17, &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 Remondia (see further on, family 



Trigoniid.e.) 



101.107._^. erenulata, gregaria, lineolata, octolirata, pasilis, Texana and Washitaensis are 

 quoted from North America in Meek's Cheek-list of cretaceous fossils (Smiths. Misc. Coll., 



No. 177, 1864, p. 11). 



108-110.— J. Conradiana, Matliewsonii, and Tuscana are from California (Pal. Calif, i, 



pp. 178-179). 



111.— ^L dubia, d'Orb., Voy. Am. merid., tom 3™-, 1812, p. 105. 



112-113.— .f/. truncata, Buch, (ibid p. 25), and J. e.ro//m, d' Orb., (ibid. p. 83) ; the last is 

 either a Prmconia or a Caryatis. 



114-124.— From Palestine Conrad described in Off. Rep. of Lynch's exped. J. ;«?<e;-o«tf/,i, 

 undulosa, luciuoides, sub-cordata, Syriaca, orientalis, ptrvetus, engonata (?), arctata. I only know 

 these names from Fraas' reference in Wiirt. Natur. Jahresh., xxiii, 1867, p. 234; he says that the 

 last seven names are based upon undeterminable casts. A. undulosa he believes to be A. formosa, 



* Fiivre (Moll. foss. de Lemberg, 18G9, p. 115,) identifies with this species A. suh-cequilateralis, Alth, from 

 Galieia.
