condition and rather abundantly at Antwerp in the Scaldisien and Poederlien 

 deposits, where they are evidently in situ. 



The Oakley shells are generally costated longitudinally, the costge extending to 

 the body-whorl as shown in Wood's figure, although they are more numerous and less 

 prominent than in the dextral form described above. In the specimens of T. in versa 

 from Antwerp given to me by M. van de Wouver, on the contrary, the costge are 

 inconspicuous or are confined to the upper whorls, corresponding to Nyst's figure 

 of 1843 and to his figure 2 /> of 1881. Similar fossils occur occasionally in the 

 English Crag, one of them from the Coralline Crag of Boyton being here given 

 (PI. II, fig. 6). Dr. Tesch has found several specimens rather finely costated in 

 one of the Dutch borings at Oss.

Specific Characters. — Shell thick, small, turreted ; spire acuminate, regularly

Remarks. — Prof. Kendall informs me he found this species at \Yalton many 

 years ago when collecting for the soi-disant Prince of Mantua. I have found an 

 imperfect specimen at Oakley, and Mr. A. Bell has reported it from the Eed Crag
