a funnel, and, in our specimens, of any other a])pendage. Anterior seg- 

 ments numerous and short, eight or more (in the type), bearing, in the 

 lower rami, one or Wo simj^le, acute sj)ines; in the middle and posterior 

 regions bearing a row of uncini. Head gibbous posteriorly, without 

 any well-marked lateral fold. 



Praxillura ornata, sp. uov. 



Body very long, slender, of nearly uniform diameter, composed of about 

 forty setigerous segments; the eight anterior bear only one or two spines 

 in the ventral rami, uncini appearing on the 9th. Head swollen and 

 gibbous above, posteriorly, abruptly flattened in front, with the anterior 

 edge bluntly rounded ; two rounded, lateral lobes beneath; front con- 

 cave beneath; no distinct lateral lobes above; numerous small, red ocelli 

 in several rows around the front margin. Buccal segment thick, coales- 

 cent with the head, long, bianinilate, the head and buccal segment together 

 about equal in length to the first two setigerous ones. The eight ante- 

 rior, setigerous segments are short, scarcely longer than broad, with a 

 well-marked suture between, and biannulate, the posterior half smaller, 

 the anterior swollen in the middle, where the setai arise, and with a red 

 band behind the setie. In the middle region, the segments are long and 

 narrow. The seven or eight anterior segments have a small ui^per fas- 

 cicle of slender acute setie, and one stout acute spine below (sometimes 

 two). On the ninth segment * there are two uncini and a spine below 

 them ; and on the tenth to the twelfth and several following there are 

 four to eight uncini, and the number increases farther back. The last 

 seventeen setigerous segments are very short. These are followed by 

 several scarcely distinct segments at the posterior end, which is tapered 

 and simple. Color pinkish white, with a bright red band ou each seg- 

 ment anteriorly, a dark red spot on each side of the head, and two bands 

 of red on the buccal segment. Ocelli red. On the middle region, the 

 bands are less distinct, and the surface is covered with dark brown 

 specks. Length, 125™"^ to 150'""\ Diameter, 1"^"" to LS-"™. Described 

 from life.

Maldane filifera, sp. uov. 



Yery slender, elongated, with twenty-one setigerous segments, of 

 which fifteen elongated ones are included in the middle region, three 

 short ones are anterior, and three short ones posterior. The head is 

 swollen, convex, and gibbous at the posterior part, abruptly flattened in 

 front, with the front edge bluntly rounded ; a low lateral fold ; buccal 

 segment ccalescent with the head. The three anterior setigerous seg- 

 ments are short, about as long as broad, with a fascicle of long, acute 



■ *In one specimen there are four, somewhat unciniform, ventral spinules, in a row, 

 ou the eighth segment, and more on the ninth, without the acute spiuule below.
