Ianthina violacea (Bolten). 



Ianthina violacea Bolten, Mus. Bolt., 75, 1798. 



Recorded, Iredale, Pro. Mai. Soc, ix, 71, 1910 (/. ianthina). 



Specimens from the Kermadecs can be sorted out into two varieties, 

 a larger conoidal form and a smaller depressed form, between which it 

 seems impossible to draw a satisfactory line. Possibly the small depressed 

 shells are young, and afterwards the descent of the body-whorl gives them 

 a more conoidal appearance. But, of course, it must be admitted that 

 if only four species are recognized in the genus, then /. violacea must be 

 counted as very variable. I include J. communis Lam. and J. balteata 

 Reeve of Suter's Manual under this species.
