Desc. Body 14 inches to 2 feet long, linear-elongate, somewhat 

 compressed, tapered at the tail, smooth, dusky, with bluish and 

 greenish shades reflecting a metallic lustre, the branchial leaflets 

 generally clouded in the centre with a dark undefined spot. Head 

 quadrangular ; the proboscis covered, on its lower half, with fleshy 

 papillse arranged in about twelve rows. Eyes black. Antennae very 

 short, conical. Segments very numerous, the post-occipital not 

 larger than the following, hearing on each side four rather short 

 setaceous tentacular cirri, of which the two anterior are shorter than 

 the posterior pairs, and under these there is a concealed rudimentary 

 cirrus. Feet all alike, the superior cirrus forming an obliquely 

 heart-shaped, shortly stalked leaflet, veined, entire, smooth ; the 

 inferior cirrus is similar in structure and nearlv so in figure, but it is
