478 CRETACEOUS PELECYPODA 



11. Diploschiza, Conrad^ 1866^ (Am. Journ. Conch., 11, p. 77). Sub-ovate 

 inequivalve ; smaller valve concave, both of a laminated structure and with trun- 

 cate, deeply-notched or emarginated beaks. Type, _D. cretacea^ Con. (L cit., p. 77, 

 pi. 9, figs. 2-3). 



Conrad says that " the shell seems to have been attached by the umbo of 

 the larger valve, the truncature of which reminds us of the truncated beak of 

 Terebratulay It is a curious shell, and, if perfect, would indicate a greater simi- 

 larity to a Brachyopod form than any I am acquainted with. 



List of Ceetaceous species. 



1. — Anomia Neocomiensis^ d^'Orb.^ Pal. Fran9, terr. cret., iii^ p. 754^ pi. 489, figs. 1 3, 



2.— J. IcEvigata, Sow., (Trans., Geol. Soc, Loud,, iv, pi. 14, %. 6,) from the lower Green- 

 sand and Neocomien. 



2>,—A, costnlata, Roem., (Nordd. Oolit., Naehtrag, 1839, p. 24, pi. 18, %. 5,) from the Hills. 



4.—^. convexa, Sow., (Trans., Geol. Soc., Lond., iv, pi. 14, %. 7,) from lower Greensand. 



h.—A. pseudo-radiataj d'Orb., Prod, ii, p. 84, =^mdiata^ Sow., (non Risso), Trans., Geol. 

 Soc., Lond., iv, pi. 14, fig. 5. 



6. — A,j[)a]pyTacea, d'Orb., Pal. fran9, terr. cret., iii, p. 755, pi. 489, figs. 7 10. 



7.— J. suh^mncata, d'Orb., (Prod, ii, p. 171, = A. tmmata, Geinitz, (non Linne,) Charac- 

 teristic Saechs. Kreid., pt. iii, 1842, p. 87, pi. 19, figs. 4-5,) from Bohemia. 



8.— J. semiglobosa, Geinitz, (Quadersandst, 1850, pi. xi, figs. 6—9), from Kieslingswalda. 



9. — A, lamellosa, Eoem., (Nordd. Kreidef., p. 49, pi. 8, fig. 3). 



10.— J. granulosa, Roem., (iUd., pi. 8, fig. 4), from Riigen. Only the convex valve of this 

 species is known; the hinge margin is said to be thickened, with 3-4 vertical, conic, prominences. 

 This would indicate that the species in question rather belongs to the Spondylid^ than to the 



ANOMIIDyE. 



11-12. — A. suhmdiata et eoccissa, Reuss, (Boehm. Kreidef., pt. ii, p. 45, pi. 31, figs. 15, 18, 19).

 pi. 18, figs. 38, 39), a very remarkable species, but it is not clear whether the name Cyclostreon is 

 applicable to it.
