prominent, with large fascicles of long, slender seta? in the lower rami, 

 and much shorter and stouter ones in the upper rami. The appenda- 

 ges, including setae, equal or exceed the breadth of the body. Breadth 

 of body, exclusive of appendages, 7™™ ; length of the latter, without 

 setaa, S-S"^"" ; with setaj, 10'""; length of body to the 15th segment, 

 25™"\ The setae of the upper ramus are very stout, and all of nearly 

 the same form, the upper ones being merely smaller and stouter than 

 the rest ; they are nearly straight or slightly recurved, with rather 

 conspicuous, moderately close transverse series of denticles, which ex- 

 tend nearly to the ends, leaving only stout, naked, straight tips. The 

 setae of the lower ramus are much longer and far more slender, with 

 a long, slender shaft, and a slightly expanded terminal portion, which 

 is conspicuously, but not closely, spiniilated on both sides to the tips ; 

 many of these are nearly straight, but most are slightly curved ; the 

 upper ones are most slender, and mostly have the tips only very 

 slightly bidentate, and the spinules exceed the diameter of the setae 

 and increase toward the end, the last ones projecting considerably 

 beyond the tip ; the middle ones are about twice as stout, having the 

 terminal part more expanded ; their spinulation is similar, but the 

 tips are more distinctly, though slightly, bidentate, the denticles be- 

 ing partially obscured by the terminal spinules that project beyond 

 them ; the lower ones are moi-e slender and like the upper ones in 

 form and character.

 200 fathoms (G. O. Sars). 



Our specimen is imperfect, but the head and seta? are quite peculiar. 

 The latter are remarkable for the length of the spinules, and for the 

 minuteness of the denticles at the tips. — A. E, V. 



Antinoe angusta Verriii, sp. nov. 



Body narrow, rather slender, elongated, tapering gradually pos- 

 teriorly. Head small, short, rounded, broader than long, the lateral 

 lobes short, not prolonged into points anteriorly, but obtusely rounded ; 

 the lateral borders also well rounded. Eyes small, nearly equal ; the 

 postei-ior pair situated on the dorsal side of the vertex ; the anterior 

 pair farther apart on the outer and upper surfoce of the lateral promi- 

 nences. Tentacle long and very slender, about three times the length 

 of the head; antennae small and short, scarcely one-third as long as 

 the head ; palpi moderately large, glabrous, considerably longer than 

 the tentacle. Dorsal cirri slender, pretty regularly but not closely 

 covered with slender papillae. The lateral appendages, except ante- 

 riorly, bear large fascicles of long, fine capillary setae, which gives a
