this peculiar fossil than the Teridinaj, to which I at first supposed it to belong. The 
fossils appear to be crypt-like tubes quite closed at the anterior end, without any trace 
of distinct valves, such as would be apparent if it related to Teredo or its allies. 
The specimens closely resemble a Hocellaria figured by Stoliczka* from the 
Arrialoor Group, but without name, but they possess a proportionately larger tube and 
taper much more rapidly.
