As is usual in Cyclostomes, its pores are more numerous than those of the zooecia; and they 

 are also distinctly larger. The ooeciostome is terminal. In the specimen figrired it is seen 

 sideways; although, as a second bifurcation is formed at its level, it would have been seen 

 in frontal view [f the branch had been arranged with the plane of the second bifurcation 

 horizontal. In other specimens in which no second bifurcation of the fertile branch takes place, 

 the ooeciostome is situated symmetrically with regard to the proximal end of the ovicell. which 

 is more or less pyriform. In fig. 1 1 the distal lip of the ooeciostome is seen to be curved over 

 the ooeciopore, as a sort of hood, thus resembling the ooeciostome of Tiibulipora phalangea ; 

 and its proximal lip is hardly developed. In some of the other specimens the distal lip does 

 not have this hood-like character; and the ooeciopore is transversely oval, with its proximal 

 and distal lips about equally developed. The type-specimens (Brit. Mus. 75. 5. 29. 30) of Pustu- 

 lopora delicatula Busk show ovicells of the general character of those here describecl in two 

 of the branches. 



Measurements, in u.: 



Width of branch at lower end of fig. 11, 250 ; of left branch, fig. 11, 400; 



Length of part of ovicell visible in the same figure, measured in a straight line, 1,950; 



Greatest width of ovicell, as seen in the same figure, 450 ; 



Diameter of zooecia, fig. 11, 75 — 100; of orifices, So. 



The specimens here describecl appear to agree closely with E. wasinensis, which Mr Waters 

 regards as including E. deflexa Smitt, 1872 (nee Couch). The agreement is manifested in the 

 form of the zoarium, in the measurements of the various parts, and particularly in the characters 

 of the ovicell and of the ooeciostome. Waters particularly comments on the fact that none of 

 the zooecia pass through the ovicell.
