Fig. 35. — Genus Cupularia Lamouroux, 1821 



A-K. Cupularia lowei Busk, 1852. A. Decalcified preparation, looked at from 

 the front. Through the membrane the bundles of muscles attached to it can be seen 

 and they pass through the frontal pores, X 50. B. The same preparation focused at 

 a lower level, X50. The circular opening is shown through which the polypide 

 passes and the tubular connection from this opening to the neighboring zooecia. 

 The polypide is faintly shown in the right-hand zooecium. C. The same prepara- 

 tion seen from the dorsal surface, X50. A line of muscles (m) reaching down to 

 the zooecia 1 chamber is seen, and the polypides arc usually alternately right and 

 left in each radial row of zooecia. D. Dorsal surface showing pore at the end of 

 the groove, X 25. E. Somewhat pressed down, so that the row of muscles are seen 

 laterally, X85. F. Lateral section, diagrammatic, showing rows of muscles attached 

 to the lower membrane (I. m.) and to the zooecial chamber (z. c). G. Vibracular 

 chamber, showing the peculiar body ending at the circle in the membrane, X85. 

 One bundle of long muscles, as well as the short ones, is shown. H. Chamber 

 of peculiar body of the vibraculashowing two small glands (gl.), X250. I. Muscles 

 leading to fascia, which is attached to the base of the seta, X 150. J. Vibracular 

 chamber above the zooecial chamber, X 85. K. Muscle of vibraculum, X550. 



L-N. Cupularia johnsoni Busk, L. Operculum from inside, X150, with the 

 bordering ridge or trabeculae united to the zooecial border. M. Seta, X85.
