Scalaria communis (Common Wentle-trap). Moderately- 

 common. Same shape as the preceding, but the whorls 

 more distinct, and the ribs thicker and more prominent. 



PYRAMIDELLID^E. 



Aclis supranitida. Rare. A pretty but very small shell, from 

 one-tenth to three-tenths of an inch long, conical or 

 turreted in shape. Good specimens are ornamented with 

 raised spiral lines or ridges. It is considered rather rare 

 as a British species. Found by collecting and washing 

 the sand as previously stated. 



Aclis ascaris. Also one of the rare minute species, and found 

 with the above. 



Eulima polita. Very rare. Lanceolate or tapering in shape, 

 being about five-eighths of an inch long and one-eighth 

 broad at the base ; colour, a shining porcelain white. 



Eulima subulata. Not uncommon. Very narrow, finely 

 tapering, light brown, with spiral bands of a darker shade. 



Chemnitzia elegantissima. Very rare. A minute, white, spiral 

 shell, with elevated oblique ribs on the whorls. Some- 

 times found along with A. supranitida. 



Chemnitzia rufa. Found with the above. 



Odostonna interstincta. Rare. Found with the above. A 

 minute species, requiring the aid of the microscope for 

 identification. It is perfectly white, with longitudinal ribs 

 upon the whorls. 



Odostomia indistincta. Odostomia rissoides var. dubia. These, 

 like previous minute species, are rare, not only on the 

 Southport shore, but generally ; they are found when 

 searching for Foraminifera, most of them being difficult
