Affinities. This species appears to me to be very different from 

 the E. raripora, D'Orb., 1 which has very few zooecia in a zoarium, 

 and more highly raised peristomes. It is more nearly allied to a 

 form figured as E. raripora by Beissel, 2 but the evidence is not 

 sufficient to show their identity. 



The species differs from E. cellarioides, Lamx., by the greater 

 regularity of the branches and of the arrangement of the zocecia ; 

 for E. cellarioides, as known from specimens, is closely allied 

 to E. raripora. The species here described also differs from 



E. nidulata, owing to the greater length of the branches, which 

 are regularly cylindrical and not clavate. 



D'Orbigny's brief diagnosis of his E. sulirregularis suggests that 

 it is this species.
