where it takes the place of Actxonina pulla. Indifferent specimens, smaller than the 

 one figured, are not rare. I have one specimen from the Pea-grit of Leckhampton.

Descrijjtion. — Morris and Lycett say : — " Shell ovate, spire elevated, somewhat 

 acute ; whorls (six) convex, the last whorl sub-cylindrical ; aperture ovate ; the 

 surface with numerous regular punctated encircling strise." The above descrip- 

 tion refers to specimens either from the Millepore-bed or the Scarborough Lime- 

 stone. 



Relations and Distribution. — More elongated and oval than Actseonina Sedgvici, 

 and probably a more widely distributed form. I have specimens from the 

 Scarborough Limestone of Scarborough Bay which are rather stouter than Morris 

 and Lycett's type. Actseonina (Actason) pulla also occurs in the Lincolnshire 

 Limestone at Weldon, and in the Inferior Oolite of Hook Norton (Walford 

 Collection). These are all specimens without folds on the columella. But it is 

 quite possible that, in some instances, imperfectly preserved specimens of Action 

 (Tornatellaea), such as Actseon ooliticus, are set down to Koch and Dunker's species. 

 In this way Actseonina (Action) pulla is a convenient name for any small and 

 badly preserved specimen of the striated Tornatellidae. 



416. AcT^ONiNA " PULLOiDES," Plate XLII, fig. 16 and 16 a. 



Description. — This is a small form, from 5 to 6 mm. in height and with a spiral 

 angle of about 58°; oval-oblong, number of whorls five, tumid with a slight ledge 

 on the posterior margin, which is marked by an impressed line. Body-whorl about 

 twice the height of the spire. The texture of the shell is smooth with very fine 

 striatious, which have a tendency to become effete towards the centre of the body-
