. Bulletin of the Museum of Comparative Zoology at Harvard College. Zoology. Fig. 7. Inferior nectophore of Quoy and Gaimard's Abyla trigona of about 24 mm. in height now referred to A. carina. A. Left lateral view. (Dashed line indicates fragments which have broken away from nectophore.) B. Detail of basal portion of second specimen of about 28 mm. iiectosac. The right lateral tooth may, however, be weaker and some- what displaced. The dorsal tooth and the two ventral teeth are es- sentially straight. The lip between the two latter is thickened and on its free dorsal edge next to the opening

C'ormidia have been found on stems of the superior nectophores of most species of Ahyla so that we now know that the "Amphiroa" type of eudoxid, usually referred to A. trigona, is characteristic for the genus as a whole.
