Description. — A large series of this species was available to me in 

 the course of this study. The mantle is moderately long and slender, 

 tubular, with parallel sides for about three-fifths of its length, the last 

 two-fifths conical, ending in a blunt point. The anterior margin is 

 produced dorsally in the midline with a small rounded lobe; ventrally 

 it is emarginated beneath the funnel with low angles on each side. 



The fins are small and short, occupying about half the mantle 

 length. They are broad rhombic, round on the outer angles, and with 

 small free lobes anteriorly. The anterior margin is slightly convex, 

 the posterior margins slightly concave. They are united around the 

 end of the mantle by a low ridge. 



The funnel is short and stout and reaches to the level of the pupil 

 of the eyes. The locking apparatus is of the usual type, simple and 

 straight. The funnel organ is normal and there is a large terminal 

 semicircular valve. 



The head is large, wide, and flattened dorsoventrally. It bears 

 large eyes. There is a small olfactory crest posterior to the eye and 

 a small pore between the eye and the base of the second arms. The 

 ventral surface of the head is deeply excavated for the funnel. 



The arms are long and m the order 3.2.4.1. Arm I is slender 

 and strongly compressed and bears a keel for its entire length. II is
