from Nipf near Bopfingen and Stuifen in Germany, also Brodla, 

 Sanka, Balin, Eegulice, Kobylany, etc. 



Ols. Terelratula lullata, Sowerby, from the Fullers Earth 

 has long been regarded as a synonym of this species, Mr. J. F. 

 Walker, however, has found that lullata has a septum and long 

 loop, and therefore belongs to the genus Waldheimia.

. A species constant in shape, and of which very slight varia- 

 tions occur, the chief one being a thickening of the base of the 

 valves. Mr. Deslongschamps quotes this species from the zone 

 of Am. Parkinsoni, but in this district I have never found it out of 

 the zone of Harp. Murchisonse, and Mr. J. F. Walker informs 

 me that it occurs in a sandy bed under the pea-grit, in the 



Cotteswolds (Gloucestershire) ; that is to say in the very base 

 of the zone of Am. Murchisonse. Tereb. Etlieridgii is not at all 

 common, but it is distributed through the Murchisonse zone of 

 this district. 



Localities. Bradford Abbas, Drimpton, etc. (Dorset) ; Stoford, 

 Haselbury, and near Gorton (Somerset) ; also Dundry (Somerset) 

 and the Cotteswolds (Gloucestershire) ; and Montreuil Bellay 

 (Maine and Loire), and Wiirtemberg.

Our specimens of this species are slightly different from most 

 of the Cotteswold specimens in not having a slight depression in 

 the smaller valve. Still the peculiarly raised larger valve, the 

 extremely flat smaller valve, and large foramen serve well to 

 distinguish this from any other species, and show at once that it
