 {Avier. Jour. Sci., xi, p. 100, pi. i, fig. 18), from the Claiborne 

 Eocene, identical. 



This European shell is reported from the German Oligocene 

 by Speyer {Pa/. 16, p. 211, pi. 23, figs. 9, a, b, c; pi. 24, figs, i, 

 a, b, and SoUingen, p. 278); from the Bordeaux beds by Degrange- 

 Touzin (Le Thil) and Benoist (Cat. p. 336); and from the Paris 

 basin Oligocene by Cossmann and Lambert (Olig. d'Etampes, p. 

 150, pi. 5, figs. 10, a, b, c).

Bronn (Index Palaiontographicus, 1848, p. 1153) considers 

 this species synonymous with 5. stramineum L. and ^. canalicula- 

 tum Lmk. But Dall ( Trans. Wag. Free Inst. Sci., vol. iii, p. 324) 

 says ornaium is a synonym of canalicvlahim Con., but not of can- 

 alicvlahnn Lamarck. The American shell is found in the Ala- 

 bama Eocene. 



Mourlon (Geol. de la Belgique, 2, p. 196) reports 5. canali- 

 culatum Lmk. from the Oligocene of Belgium.

This Eocene species is found by Heilprin (Contr. Tert. Geol., 



p. 85) to be very close to O. bcllovacina Lmk. The latter is cited 



by Nyst from the Oligocene of Belgium (Coq. et poly. foss. , p. 318).

According to Heilprin, this species is .so clo.se to .So/ccurtus 



{Sanguinolaria) compressus Sow. that, at first sight, they may be 



readily mistaken (Contr. Tert. Geol., p. 90). The American 



species is Eocene.
