from near Gorton, from the zone of Murchisonse. They most 

 resemble E. Deslongschamp's figure 4 on plate v., and show 

 slightly the extra biplications. 



Localities. Near Gorton (Somerset). E. Deslongschamps 

 quotes it from the zone of opalinus, from several places in 

 France, such as Maltot, Fenguerolles, Bayeux, &c. 



21. TEREBRATULA (EHTHYBis) PROVINCIALIS, E. Desl, 



1873. TEKEBKATULA (EI-ITHYRJS) PROVINCIALIS, E. Desl., Brach- 

 Jurass., plate Ixxxiv. 



This species is to Terelratula curvifrons what Wald. Heriani 

 is to Wald. carinata. The very much incurved beak is its dis- 

 tinguishing character. It is also deeper and narrower in propor- 

 tion than Tereb. curvifrons, but the sinus in the smaller valve is 

 not so deep. Two undoubted specimens of this species have 

 been found in the Murchisonse zone, near Gorton, one by Mr. E. 

 Cleminshaw, and the other by myself. 



Localities. (British) near Gorton (Somerset). (Foreign) La 

 Proveoce (France) and several places in Spain.
