the estuary of the Dee (Siddall), the Dublin coast (Balk will and 

 Wright); Westport, Ireland (Brady), and Bognor (Earland). In 

 view of the proximity of Bognor to Selsey, we now consider that 

 Earland's recorded specimen should be doubtfully regarded as 

 recent

Fossil. A single specimen from under the rocks at the Mixon 

 Beacon, doubtless derived from the detritus of the Alveolina lime- 

 stone, of which they are mainly composed. The specimen agrees 

 in all essentials with Millett's figure (supra). The species has not 

 previously been recorded as fossil, except by Terquem (supra), 

 from the Eocene of the Paris Basin. The habitat of recent 

 specimens is the shallow waters of tropical shores, hence agreeing 

 very well with the source of origin of our specimen.
