When seen from the narrow side, the general outline of the body is almost ellipsoidal. A view of the broad side, however, shows a pear-shaped outline, this being due to the wide-flaring oral lappets. The aboral apex is not so acute as in Bolinopsis inftindibulum, and not so blunt as in Lesueuria hyhoptera. The. Fig. 8.—Sense-orga

The oral lappets are each about two-fifths as long as the entire animal and are even wider than they are long. The 4 auricles are flat and ribbon-like, and about one-fourth as long as the body of the animal. Their centrif-.
