 II, 123. 



Delphinida Lamk 1804, Ann. du Museum IV, 

 108. GoLDFUSS and Hisinger have re- 

 ferred several of the Oriostomata to 

 this genus. True Delphinula begin to 

 appear in the strata of St. Cassian. 



Dentalium L. 1758, S. N. ed. X, 78;"). The 

 oldest species known are Devonian. 



Ditaxopus Rafinesque 1839, Bull. Soc. Geol. 

 X, 378. Perhaps a Bellerophon. 



Duncania Bayle 1879, flourn. de Conchy- 

 liologie vol. 19, 35, later changed into 

 Macrochilina. 



Eccyllomphalus (not Eceuliomphalus) Port- 

 lock 1843, Rep., 411. Most species 

 nothing but evolute Euomphali. Ac- 

 cording to the derivation the name is 

 to be written as above. 



Elenchus Humphrey 1797, Mus. Calonnia- 

 num . . ., according to Mac Coy Carb. 

 Foss. Ireland, 42, a species in the Old 

 Red Sandstone of Ireland, but may 

 probably belong to another genus. 



ElUpsolithes Sowerey 1813, Min. Conch., 

 vol. I 81, non Montfoiit, wliose genus 

 embraced only Polythalamia. Sowerby 

 has himself later in Min. Conch, vol. 

 5 p. 107 corrected his species and in- 

 dicated two as Cephalopoda and one, 

 Eu. ovatus, as a Bellerophon.

Euphemvs Mac Coy, 1844 Carbonif. Foss. 

 of Ireland, 25. Although M'Coy him- 

 self later, in Brit. Pala^oz. Foss., 308, 

 declared that this genus was identical 

 with Bellerophon, the slit band having 

 by oversight been described as defi- 

 cient, Waagen and De Koninck have 

 again tried to revive it. But on com- 

 paring the species described by both 

 these authors as belonging to Euphe- 

 mus, it is easily found that the Eu- 

 phemus of Waagen cannot be recon- 

 ciled with that of De Koninck. While 

 the latter author as Euphemi describes 

 E. Urii and other Bellerophons, Waa- 

 gen makes us acquainted with several 

 forms so strange, that it may be doub- 

 ted whether they are Gastropoda at 

 all or not rather Cephalopoda of some 

 new genus.

 first in Trias.
