There are numerous fragmentary specimens in the Cretaceous from 

 Trinidad that may be referred to the above species with little ques- 

 tion. The tubes are somewhat collapsed, but they have the character- 

 istic irregular curvature and especially the roughened surface often 

 carrying broken spicules. No branching specimens were found. 

 Franke ^ has recorded very similar, branching fragments from the 

 German Cretaceous as '"'' Rhizmmnina algaejormis.'''' White ^ records 

 a tubular fragment from the Velasco shale of Mexico as '"'' Rhizam- 

 nrnia indivisa.''''

Specimens of this species are usually collap.sed to some extent, 

 especially the later chambers, like those in the specimen here figured. 

 The Cretaceous specimens seem to be exactly identical with the Re- 

 cent ones that occur in Atlantic waters. As already noted under 

 Pelosina complanata^ there is a distinct possibility that those speci- 

 mens may represent the megalospheric stage of Eormosma glohuli- 

 fera. This is one of the species that give the close relationship of
