1 Bolita^na microcotyla lias a soft ovoid body of gelatinous consistency, and 

 a reddish-purple colour, somewhat resembling Cirroteuthis, 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.
