Animal small, its Body firm and fleshy, cylindro -conic in 

 outline ; usually widest anterior^, thence tapering rapidly 

 past the fins to a soft, attenuate point behind. Anterior edge 

 of mantle smooth, but broadly emarginate ventrally between 

 the obtuse points into which it is produced on either side of 

 the funnel, while again in the nuchal region it is extended to 

 a rounded obtuse point. Fins large and triangular, individu- 

 ally longer than broad ; maximum length about one-half 

 that of the mantle, the distance from tip to tip across them 

 about two-thirds the mantle length ; outer angles sharply 

 rounded ; anterior margins shghtly convex and cut in where 

 they join the body to form a somewhat angular anterior lobe ; 

 posterior margins longer, slightly convex, joining the body 

 at a point just in front of the end of the gladius but at a 

 distance of perhaps one-fifth the mantle length from the 

 extreme tip of the body. 



Head squarish, moderate in size, a little longer than wide ; 

 slightly convex above, concave below\ Olfactory crest com- 

 prising a sinuous V-shaped fold, the dorsal segment com- 

 mencing at the hinder dorso-lateral angle of the head, the 

 ventral segment longer and more sinuous ; a similar but
