It is quite possible with large quantities of the species to form a 

 series, beginning with the type and ending with this variety. Many 

 intermediate stages can be picked out. I possess an example of this 

 variety with the umbilicus almost obliterated. 



III. — Var. clausa Jeffreys maybe either banded or horn coloured. 

 I have made long observations upon this variety, but cannot bring 

 myself to believe in its validity. In my opinion it is only a mons- 

 trosity. I have this form in all stages, from the type to specimens 

 with the umbilicus totally eradicated. I venture to suggest that this 

 variety be expunged from the British list.
