8 BULLETIN OF THE 



strata; these are small, fusiform or oblong rods and prisms. Some of them are 

 long, slender, triquetral, and nearly smooth (Fig. 5 b, d), or sparingly waited 

 near the ends; the larger of these measure .35 by .03 mm. to .29 by .03 mm. 

 Others are shorter, more rod-like, and covered with scattered, minute, conical, 

 obtuse warts (Fig. 5 c) ; some of these are swollen in the middle with promi- 

 nent warts; most of them are roughened and obtuse at the ends; they measure 

 .25 by .025, .23 by .025, .20 by .03, .20 by .025, .15 by .02, .14 by .015 mm. 

 Some of smaller size (.10 by .015 mm.), but similar in form, are strongly 

 waited all over (Fig. 5 b, e). 



A single specimen Avas taken south of George's Bank, at Station 307, in 980 

 fathoms, N. Lat. 41° 29' 45", W. Long. 65° 47' 10". 



Distichoptilum Verrill. 



Amer. Jour. Sci., XXIV., Nov. 1882, p. 362. 



Slender pennatulids, with an axis through the whole length. Polyps ar- 

 ranged alternately, in a simple row, on each side. Calicles bilobed, appressed. 

 Zooids three to each polyp, one in front and one on each side of each cell. 

 Spicula abundant in the calicles, rachis, and stalk; those in the stalk are 

 small, oblong, triquetral, interwoven. 



Distichoptilum gracile Verrill. 

 Amer. Jour. Sci., XXIV., Nov. 1882, p. 362, note. 

 Plate I. Figs. 1, 1 a, 1 b. 



Long and slender, with a long stalk. Polyp-calicles rather large, rigid, 

 closely appressed, with two sharp terminal lobes, filled with spicula, conceal- 

 ing the opening, and overlapping the base of the calicle in front. Zooids 

 small, not exsert, showing as small white spots at each side and in front of 

 each calicle. Stalk long, slender, with a long narrow bulb. Color bright 

 orange-red, due to the spicula; end of bulb yellowish. 



Length, 18 inches, or 456 mm.; breadth in middle, 2 mm.; length of stalk, 

 100 mm. 



The spicula of the calicles and rachis are long, triquetral, both oblong (Fig. 

 1 b, c) and fusiform, obtuse or acute at the ends, varying in slenderness; those 

 of the stalk (Fig. 1 b, d) are much smaller, of the same general form, but 

 mostly oblong, with obtuse ends. 



A single perfect specimen of this curious species was taken by the U. S. 

 Fish Commission, August 26, 1882, at Station 1123, in about 700iathom3, 

 S. E. of Nantucket Island, in N. Lat. 39° 59' 45", W. Long. 68" 54'. 



Attached to this specimen was a fine example of Astronyx Loveyii, which had 

 the same bright orange-red color as the coral. In alcohol, however, this ophi- 

 uran rapidly lost its color, while that of the cor^l was not much altered.
