is more conspicuous. We have observed that in most species of 

 Terebratulidse the younger shells have the beak generally straighter 

 than it is in the mature specimens.

Deslongchamps and others consider the granular surface as 

 characteristic of the genus Kingena ; therefore we have placed our 

 shell in that genus, although we have not been able to examiue the 

 loop. 



This species is easily distinguished from the other Cretaceous 

 Kingence by its peculiar shape and large size. There are two large 

 species of Kingena figured by Stoliczka, in his monograph on the 

 Brachiopoda in the Cretaceous Fauna of Southern India — a circular 

 form, K . asperulina, and an ovoid form, K. shalanurensis ; these 

 cannot be confounded with our species. The Terebratula pectoralis 

 of Ecemer is a more regular pentagonal shell, the hinge-line is 

 straighter, and it is not depressed towards the lateral margins. 



We have much pleasure in naming this species after Mr. E. T. 

 Xewton, F.R.S., who has kindly assisted us in determining the 

 fossils which occur in this deposit.

The RJtgnchonellce found at Shenley which we consider to belong 

 to this species have finer plaits than are exhibited by those which 

 occur at Warminster. Some of the larger specimens seem to connect 

 this species with Bli. nuciformis, Sow., the plaits being rounded at 

 the front-margin. Schloenbach states that Eh. Grasiana from 

 the Harz attains the dimensions of 20 millimetres (our biggest 

 specimens measure 18 mm.), and he also remarks that this species 

 is very like JRh. nuciformis. 



Sowerby figures ('Min. Conch.' pi. dii, fig. 3) a coarse-ribbed shell 

 as Terebratula nuciformis, which shows « no details whereby the 

 species can be recognized. 



Bhynchonella Grasiana occurs at Warminster in the Upper Green- 

 sand, and in Dorset, and is common in the arenaceous Cenomanian
