1 Bolitmna microcotyla has a soft ovoid body of gelatinous consistency, and a reddish-purple colour, some- 

 what resembling Girroteuthis, but destitute of fins and with the mantle-opening very wide, extending beyond the eyes 

 instead of being a narrow aperture immediately surrounding the funnel. The arms are comparatively short and slender, 

 webbed almost up to the extremities, and provided with a single row of very small suckers. The jaws are very little 

 curved, and the radula is remarkable in that the rows of teeth present a serial repetition, the fifth resembling the first.
