Brachiopoda. 



This class is only represented by a few entire specimens and detached valves of 

 Thecidea maxilla, Hedley,* which have been found in loose material from a depth of 

 65 feet in the Main Boring, and below the floor of the lagoon between 50 and 144 feet. 

 The specimens are of small size ; about 4 millims. in length by 275 millims, in 

 breadth. This species was first obtained by Hedley attached to loose sheets of dead
