74 CRETACEOUS PELECYPODA 



51-58. — A. Astieriana, Carteroni, Marullensis, Corrmeliana of d'Orbigny, A, inflata, kg., 

 sp.j, A. valangiensis, P. and Camp.^ A. OrUgnyana, Loriol^ A, hrevissima, P. and C, are all species 

 oi Anatina ; the last may belong- to the sub-genus Flectomya, should this really prove to be distinct 

 from Ana f ma, 



59-60. — A. MoUnaldina, d'Orb., A. gurgitis, P. and Camp.^ belong- to the sub-genus Cer- 

 comya; the first was also found by Coquand in the Aptien of Spain. . 



^1' — ^- Bhodani, P. and E. (closely allied to Mamllensu), and A. Eeherti, P. and Ren., are 

 Anatin(E ; the last species is a pecuHar form, like a Gresslya. 



^%.^^, — A, tJiraciformis, Buv., A. Royaria, d'Orb., A. Nadclasi are Anatin(E. 



65-68. — A. lanceolata, Gein., harpa^ Kner, and elongata, Reuss, belong to the sub-genus Cer- 

 comya, but they are based upon such bad or imperfect specimens that a good specific determination 

 is quite impossible. 



69. — A. producta, Zittel, is a Cercomya (vide Denksch. Akad., Wien, xxiv, pi. ii, p. 114, &c.)- 

 The same author also described A. Royana, d'Orb., from the Gosau deposits of the Austrian Alps. 



70. — A, Cenomanensis, Guer anger (Album paleont. de la Sarthe, pi. xv, fig. 7), is a Cercomya. 



71. — Anatina solenoides, d'Orb., (Siid.-Bayerns Leth. Geogn. by Schafhseutl, 1863, p. 175, 

 pi. xliv, fig. 3). If this at all belongs to the Anatinid^, of which there is no distinct proof, it 

 would belong to the group of the compressed forms which Agassiz called Flatymya. The shell is 

 said to be a cretaceous one, but it certainly has very little or nothing in common with the FJiola- 

 domya solenoides of Deshayes, which d'Orbigny places in Anatina. 



72. — A. ntgosa, Bell., non Lam. (Mem. Soc. GeoL, France, ii. ser., vol. iv, p. 233, pi. xvi, 

 fig. 13) . A nummulitic species from the neighbourhood of Nice is quoted by Eichwald (Leth. Ross., 

 livr. xi, 1867, p. 727,) from some cretaceous strata of Russia. The identification may well be ques- 

 tioned, judging from Eichwald^s description, who states that the posterior side is longer than the 

 anterior, while in Bellardi^s species the contrary is the case. Bellardi^s species itself is by no means 

 certain to be an Anatina ; it is more probably a Thracia, but should it prove to be either one or the 

 other, its specific name has to be changed. 



73. — A. (Cercomya) acuminata, Eichwald, Leth. Ross., livr. xi, p. 728. 



74. — A. Jettei, Coq., is an Anatina, and rather like A. Roy ana. 



75-76.—Meek quotes in No. 177 of the Smith. Misc. Coll. (p. 14) A. elliptica, Gabb, and 

 sulcatina, Shumard.— '^;^«?^. columUana has been already mentioned (p. 73). 



77-80. — A. Tryoniana, A. inaquilateralis, and A. lata are described by Gabb in the Palseont. 

 of California, (vol. i, p. 150, &c.). The first and second have the usual compressed form of creta- 

 ceous AnatincBj the last looks more like a caste of an Acropagia than that of an Anatina; Anat. 

 quadrata, Gabb, (ibid. vol. ii, p. 177,) may also represent a TelUnomja or a Corimya. 



81. — Anat. (Cercomya) arcuata, Forbes, is the only species of anatinin^ from the South Indian 

 cretaceous deposits j the species is quoted by Bosquet also as occurring in the upper cretaceous 

 deposits of Limbourg. 



82-84. — Anatimya anteradiata, postsulcata, and 2^a,pyra of Conrad, see No. 177 of Smiths. 

 Misc. Coll., p. 14. 



Species of, and allied to, Fholadomya (see Mat. p. 1. Pal. Suisse, iv ser., 3"^^ pt., p. 90). 

 Most of the cretaceous species of Fholadomya belong to the section mdlticostaTjE, to which also the 

 recent species is referable, and to the ovulate or PAUCICOSTAT^, only a few to the CARDISSOWES 



and TRTANGULAEES. 



85-90. — Fh. gigantea, Sow., elongata, Munst., Fh. semlcostata, Ag., Fh. Galloprovincialis, 

 Math., P/^. Figeriana, Cotteau, Fh. alternans, Romer, (all are MVLTIgO^taTjE) ; — Fh. minuta,
