Two males and two females were obtained. The males, altliougii undoubtedly 

 to be referred to thii species, present some peculiarities. The rostrum bends steeply 

 downwards from the dorsal margin, but ends in a point turned slightly forwards. The 

 posterior process is wider than in Miiller's figure, and terminates posteriorly in a blunt 

 angle. The right and left processes when apposed form a tube or siphon. The 

 appendages agree exactly with Miiller's description.
