longer than the stalk ; dorsal cirrus arising from near the base, longer 

 and more slender than the terminal cirrus ; branchial filament simple, 

 long and very slender, about equalling the dorsal cirrus and united 

 to it above its base; ventral cirrus ovate, tapering, blunt, arising 

 from near the base. The second pair of feet are similar to those of 

 the first, except that in the largest specimens there are two branchial 

 filaments, and the ventral cirrus is longer and more slender. The 3d, 

 4th, 5th, and 6th pairs have essentially the same structure, but the 

 ventral cirrus becomes gradually longer to the 6th, where it is longer 

 than the stalk and nearly equal to the terminal cirrus. The succeed- 

 ing feet are much shorter ; the ventral cirrus is a mere conical papilla, 

 which soon disappears ; the terminal cirriform lobe becomes smaller 

 and disappears after the 10th pair; the branchial filament becomes 

 larger and longer to the middle region, where it exceeds in length 

 half the diameter of the body, while the dorsal cirrus at the same time 

 becomes smaller and shorter, until it is less than one-fourth the length 

 of the branchia. 



The setae of the anterior feet consist of slender, acutely pointed, 

 curved ones, mixed with much stouter, blunt pointed compound ones ; 

 farther back there are two fascicles of more slender acute setae, and 

 in the lower bundles a few long, stout, bidentate hooks, with a thin, 

 rounded, terminal expansion. 



Color, in alcohol, pale yellowish white, but everywhere very bril- 

 liantly iridescent, with opaline lustre and colors. 



Length, Y5 to 125""" ; diameter, 2*5 to 4""". 



Common in 110 and 150 fathoms, haiils s and o. It was also 

 dredged in 1873, off Casco Bay, in 30 to 94 fathoms, and on Jeffrey's 

 Bank, in 79 to 105 fathoms. It was also abundant, on muddy bot- 

 toms in deep water, at all the localities in the Gulf of Maine examined 

 by Dr. Packard and Mr. Cooke hi 1873.

North of Saint George's Bank, 110 and 150 fathoms, mud (local- 

 ities o and s) ; Saint George's Bank, 20 fathoms (locality j). Off 

 Casco Bay, 30 to 90 fathoms, mud. Bay of Fundy, 20 to 70 fathoms. 

 Common in the Gulf of Maine, 60 to 100 fathoms. Northern coasts 

 of Europe, from Finmark to Scotland, 10 to 130 fathoms (Malmgren).
