Although the ends of the zooecia project, I think we are 
justified in uniting it with D. simplex ; but that name cannot 
be retained, as D’Orbigny called a fossil D. simplex ; and 
although the genus was afterwards changed by him to Disco- 
sparsa , it would now be Diastopora or Discoporella.

The zoarium is much raised and inflated, with 3-4 zooecia 
irregularly arranged. The width of a fully developed branch 
is 1 millim.; but some branches are thrown oft’ with only one 
or two cells in a series; and then the branch measures 0*4 
millim.

Nearly all the specimens of Terebratula vitrea which 1 
have seen from the neighbourhood of the Bay had long and 
very slightly raised colonies of Alecto. The zooecia are 1-2- 
serial, and are rather wider than in the last variety. The
