Diagnosis

Body slightly compressed. Lobes when expanded about as long as the body. Surface smooth. Auricels long and triangular with straight sides and a sharp-pointed end. Bulges above the nerve-center high, paddles not large and rather numerous. Adradial canals join the proximal part of meridional vessels. Corves of the lobe-vessels simple. Length 11cm, breadth of lobes 9cm. Colour perfectly transparent. Lobe vessels in the adult violet. The most striking feature of this Bolinopsis is the great bulk of the lobes, which are thicker than the body, and nearly circular. The lobe-vessels are extremely simple and show the characteristic arabese-shaped curves only when the lobe is contracted. The muscles in the lobe are clearly visible forming an extremely delicate network of radial and circular fibres, which however, are by no means so distinct as those in Leucothea multicornis. The body appears in its upper end decidedly truncate. The stomach is rectangular and much broader than in other species. The sense organ is situated about 1cm below the aboral end of the body.
