Corallites in general free laterally, and having but slight, circular, mural growth 
swellings. Sepéa rather thin, and sub-equal; 24 or 26; exterior zone filled with very 
large vesicles. Diameter of the Corallites about 1 inch. 
Found at Arnside, Kendal, Bakewell, Derbyshire, (Museum of Cambridge). 
This species differs from L. rvgosa’ by the small development of the growth swellings 
of its epitheca; from Z. Bronni,’ by its septa being less numerous, and its columella 
smaller, and from L. floriformis,? and L. papillata,* by its septa being almost equally 
developed, and by the great size of the vesicles of its exterior zone.
