This is a very interesting little fossil, very distinct in every 

 way from any now existing on the Australian coast. It is very 

 small, and the whorls which are angular in the middle are closely 

 covered with delicate undulating frills. Some of the undulations 

 are prolonged into concave spines on the lower whorls and the 

 upper part of the penultimate one. The aperture is orbicular, 

 enamelled and the inner lip is tubercular-; the canal is long, not 

 quite open and much curved ; the nucleus is almost unrolled, 

 erect and highly polished.
