 cavata ; lunula linea profunda circumscripta. 



Like A. juvenilis and yl. scalaris, but with the ridges laminated ; 

 some ending suddenly and others spread out into broad reflected 

 laminfB at the sides. Fig. 87 represents a much less broadly 

 laminated variety.

Platter than A. variegata, with the concentric ridges more dis- 

 tant and continuous, and all traces of the purple colouring are 

 lost, only pure brown angular markings remaining. This species 

 looks so diiferent from A. variegata that one is compelled to se- 

 parate it notwithstanding the existence of intermediate varieties.
