An7ielida of the Bermudas. 609 



bave stout curved blades, about 3 or 4 times as long as broad, 

 with strongly incurved acute tips ; the lower ones have shorter, 

 much curved, acute, claw-like blades, 2 or 3 times as long as broad. 



The oesophagus is brown, large, stout, nearly cylindrical, a little 

 contracted at each end, about ^ shorter than the stomach and f as 

 broad, occupying 9 segments ; anterior margin is entire or feebly 

 crenulate, a little emarginate dorsally ; the median tooth is large, 

 long, acute, with a wide ovate base. The stomach is lai-ge, longer 

 than the oesophagus, occupying 8 segments, cylindrical, a little 

 swollen posteriorly, covered with numerous interrupted, irregular, 

 or poorly defined rows of minute cells, not arranged in very definite 

 groups. 



A caudal region of about 14 new and small segments is being 

 regenerated on the type. 



Length of one specimen (32 segments, caudal segments lacking), 

 7.5'"'"; breadth, .75'"'"; length of oesophagus, 1.38"""; of stomach, 

 l.e™"". Another specimen (type described) with 57 segments and 

 partly regenerated caudal region is 14.5'""' long ; I'""' broad ; length 

 of oesophagus, 1.40™"^; of stomach, 1.60"'"'. 



Color, in formalin, is translucent whitish; the cirri appear dis- 

 tinctly banded with 8 to 10 small dark green spots, every fourth 

 annulus having a very distinct, darkly pigmented area. 



Rare— only two specimens were found. 



Syllis (Typosyllis) cincinnata, sp. nov. 



A strongly colored, rather large species, with numerous compact 

 segments and a highly contractile body; when preserved in forma- 

 lin usually coiled irregularly, thick and rounded anteriorly, with very 

 short, closely contracted segments, short anterior parapodia; flat- 

 tened and tapered posteriorly, with longer posterior segments and 

 more prominent parapodia and setfe ; antennje and anterior cirri 

 long, strongly beaded and irregularly curled about the head, so as to 

 nearly conceal it ; middle dorsal cirri mostly long, incurved over the 

 back ; oesophagus short with a very long tooth ; stomach very long 

 and large ; blades of set 33 mostly rather short, strongly incurved, 

 the anterior ones mostly not bidentate at tip. 



The head is small, wider than long, transversely broad-elliptical ; 

 buccal segment short. Eyes black, unequal, the anterior rather large 

 and near the sides of the head ; posterior ones about ^ as large, 

 separated by about their own diameter, and but little farther back, 

 lens indistinct.
