ME. L. EICHAEDSON ON NEW SPECIES OF 



[Nov. 1907, 



a Terebratula it was confounded by most foreign palaeontologists with 

 plaited specimens of Terebratula globata from the ParJcmsoni-Zone. 

 Mr. S. S. Buckman has given names to some of the forms which 

 it has been customary to call Terebratula globata. More in- 

 formation, however, is desirable on this remarkable group, and in 

 the meantime I prefer to call those forms which have always been 

 referred to as T. globata, Sow., T. globata, auctt., non Sow. 



Zeilleeia emaeginata (Sowerby). 



Mr. S. S. Buckman has figured a specimen of Zeilleria emarginata 

 from the Fullers'-Earth Rock of Nunney, near Frome. 1 From it, 

 the specimen obtained at Farmcombe differs in being much narrower. 

 The Fullers' Earth of Farmcombe, however, is of earlier date than 

 that of Nunney. This probably accounts for the difference, but 

 Zeilleria emarginata, of course, varies considerably in width.

Fig. 6. — Amberleya Hudle- 

 stonei, sp. nov. {Natural 

 size.) 



Shell turbinate, rotund, turrited; whorls more con- 

 vex than is usual in the Amberleya- 

 group. The ornaments consist of 

 five to six granulated spirals : the 

 first or uppermost (that nearest the 

 posterior suture) being the finest, 

 and the third and fourth the most 

 prominent ; while the sixth only 

 makes its appearance on the pen- 

 ultimate whorl (just before the com- 

 mencement of the body-whorl) as a 

 thin thread like that nearest the 

 posterior suture. There are seven 

 or eight finely-granulated spirals on 

 the base — the granulations on all the 

 spiral lines being produced by the 

 numerous transverse lineee. The 

 aperture is subcircular. 



Remarks. — This specimen was 

 submitted to Mr. W. H. Hudleston, 

 who wrote : — 

 This is too rotund and highly-ornamented for the typical Amberleya ornata.
