Fig. 64. — Genus Bugularia Levinsen, 1909 



A-E. Bugularia dissimilis Busk, 1852. A. Zooecium with free ovicell and 

 sessile avicularia, X23. B. Basal surface; the strongly angularly bent distal 

 wall is seen, X23. C. Lateral view of the ovicell, X 23. D. Distal wall viewed 

 from above, X40, with two multiporous septulae. (A-D, after Levinsen, 1909.) 

 E. Lateral wall, X 25 (after Waters, 1896). F. A frond, natural size. G. Usual 

 aspect of frontal side. H. Basal surface showing mode of gemmation of cells. 

 I. Avicularium enlarged, viewed from the front. (F-I, after Busk, 1852.) 



Fig. 65. — Genus Watersia Levinsen, 1909 



A-E. Watersia militaris Waters, 1887. A. Fragment of zoarium showing 

 the ovicelled zooecia, X 16. The radical fibers issue everywhere from the cover- 

 ing membrane of the frontal surface in the two layered colony. (After Waters, 

 1887.) B. Lateral wall showing raised ovicells and multiporous septulae, 

 X25. C. A multiporous septula, X250. D, E. Distal wall showing uniporous 

 septula, X25 and X85. (B-E, after Waters, 1896.) 



ends of two internodes of the stem. On the lower the distal wall and one of the 

 lateral thickenings are seen; on the upper the two lateral thickenings annularly 

 connected in the proximal end of the intcrnode, X100. M. Two adjacent 

 internodes of the stem, between which a new one is beginning. The lateral 

 thickenings and the parietal muscles, X 100. N. The distal end of a new formed 

 internode of the stem (in an inverted position) with parietal muscles, X 100. 

 O. A new formed stem internode beginning between two older ones, X40. P. 

 Avicularium, X 100. Q. A transverse section through a stem-internode to show 

 two lateral thickenings, X 100. (A-Q. After Levinsen, 1909.)
