where it takes the place of Acteonina pulla. Indifferent specimens, smaller than the 
one figured, are not rare. I have one specimen from the Pea-grit of Leckhampton.

Description.—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 strie.” 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 Actxonina 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. Actxonina (Acton) 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 Actxon 
(Tornatellexa), such as Actxon ooliticus, are set down to Koch and Dunker’s species. 
In this way Actzxonina (Actxon) pulla is a convenient name for any small and 
badly preserved specimen of the striated Tornatellide. 
416, Acrmonina *‘ puLLompEs.” Plate XLII, fig. 16 and 16a. 
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 animpressed line. Body-whorl about 
twice the height of the spire. The texture of the shell is smooth with very fine 
striations, which have a tendency to become effete towards the centre of the body-
