Vol. 59.] A LOWER-GREENSAND EOSSILIFEROUS BAND. 251 



Some of the specimens of Terebraiula bijolicata var. gigantea, 

 from Shenley, very closely resemble those from Warminster, 

 having the large foramen and recurved beak. The plication of the 

 front-margin varies in both localities, but some of the bigger Shenley 

 specimens differ in having their sides more laterally compressed ; 

 some specimens from Warminster also show this. 



Terebratula biplicata, var. Dutempleana. (PI. XVII, figs. 1 a 

 & lb.) 



A specimen from Shenley appears to belong to this variety. 



Dimensions: — length =34*25 millimetres ; breadth = 25 mm. ; 

 thickness=22 mm. ; and the apical angle = 61°. 



The rarity of small biplicated Terebratulce is a noteworthy 

 feature of this deposit.

The material that we have collected at Shenley is not sufficient 

 for the investigation of this species. The specimens appear to have 

 a shorter beak, and to be more triangular in shape than any of 

 the varieties figured by Vicomte d'Archiac. Some forms closely 

 resemble those figured as Terebratula subdepressa by Stoliczka in 

 the ' Cretaceous Brachiopoda of Southern India.' 



Dimensions: — length = 47 millimetres ; breadth ■= 38 mm. ; 

 thickness = 19'5 ; and the apical angle = 68°. In another specimen 

 the length = 41 millimetres ; breadth = 29'5 mm. ; thickness = 

 15 mm. ; and the apical angle = 63°.
