Affinities. This species is distinguished from the previously 

 described discoid forms by its thick zoarium, and the crowded 

 raised peristomes. Its zooecia most resemble those of B. coartata, 

 Greg. This species, however, differs somewhat in zooecial 

 characters, so that the zoarial difference is probably not merely 

 due to mode of growth ; for the zooecia in B. verrucosa are longer 

 than in B. coartata, whereas in discoid forms they are, as a rule, 

 shorter than in those with irregular encrusting zoaria. 



The species has often been regarded as the young stage of 

 B. diluviana (Lamx.). The reasons, however, for accepting 

 M. Edwards' species as distinct are given on p. 93. 



The closest ally of this species is B. polystoma (Rom.), 1 from 

 the Neocomian of Prance and Germany. This differs from B. 

 verrucosa only by having longer, more upright, and more scattered 

 zooecia. The species has been retained by Pergens, 2 and is no 

 doubt entitled to distinction. 



The specimen figured by Reuss 3 as Tubulipora stelliformis (Mich.) 

 is also a close ally of B. verrucosa, M. Edw. It differs from it 

 by the greater elevation of the peristomes ; the zoarium is also 

 much thicker and smaller. A recent Australian species, B. licolor, 

 MacGill., 4 is another ally ; but it has less crowded and longer
