 radiately ribbed, smooth, anteriorly rather largely ob-

Hab. Moretou Bay, Australia ; Stutchbury. 



A characteristic Australian species, of narrow angularly 

 keeled growth, broadly plicately wrinkled down the ante-

 Henry Stutchbury, a resident of the town of Bristol, who 

 has just departed this life, after spending many years in 

 the successful pursuit and study of natural history.
