A-F. Tervia irregularis Menegliini, 1845. A, B. Normal and short ovicelli, X 12. (After 
Waters, 1888.) C. Cordiform ovicell, X 12. (After Jullien, 1903.) D, E. The two faces of the 
zoarium. (After Harmer, 1915.) F. Comb-like process in the zooecial tube near where it be- 
comes erect. (After Waters, 1914.) 
G, H. Tervia jellyae Harmer. 1915. The two faces, X 12, o. oeciostome. (After Harmer, 
1915.) 
Variations . — The tubes are arranged sometimes in quincunx, sometimes in 
verticells, and sometimes in fascicles; the last arrangement is more frequent. The 
convexity of the dorsal is quite variable. 
In longitudinal section the tubes are very long. 
The fascicles are salient on each side of the zoarium viewed from the dorsal. 
Affinities . — This species differs from Tervia irregularis Menegliini, 1845, in 
its smaller interfascicular distance (.0.3.6 and not 0.60 mm.) and in its more narrow 
and slender branches.
