and the habit of the serial extension of the calices, toiiether 

 with the pre>ence of a rudimentary or papillose columella, show 

 its affinity with the Thamnastraeans. The subgenus Oroseris is 

 distinguished from Comoseris by the limited extent of the col- 

 lines, which do not traverse the entire length of the colony ais in 

 Comoseris, and in this respect our specimen is in agreements 

 A closely allied species to ours is Comoseris (Oroseris) regularis, 

 Fromentel, which, however, has fewer septa, and a more pro- 

 nounced papillate columella.- This subgenus is represented in 

 the Jurassic, Neocomian, Cretaceous, Eocene and Miocene forma- 

 tions. In the Eocene it is known from Europe, a.nd in the 

 Miocene from Italy.
