Annelida of the Bermudas. 653 



3 Bpiniform ones, a little more bent distally. The branchiae are more 

 slender and longer than the dorsal cirri. 



In life pale red; each segment has two narrow, transverse, paral- 

 lel, orange vittae, not extending entirely across, and a roundish spot 

 of the same color on each side at the bases of the dorsal cirri. There 

 is a dark irregular spot close to front edge of the head. 



Length, in life, 200"^°^; breadth, 3 to 3.5"°^. 



Flatts Inlet beach in shell-sand at low tide. 



This species is evidently related to A. platycephala Mclnt. (Chall. 

 Voy.), also from Bermuda, but the latter species has gills only on 

 segments 8-18, and the setae and cirri are different in form. 



Cirratulus (Audouinia) capillaris, sp. nov. 



A small species with very long slender cirri. Head short, some- 

 what depressed, bluntly rounded in front, confluent with the buccal 

 segment; the next two segments are hardly distinguishable, except 

 below, and thicker than those that follow, which are subequal, but 

 increase in length posteriorly and decrease in diameter, some being 

 as long as broad ; the posterior ones become small, short and 

 crowded. 



Setae and cirri begin together on the 2d body segment; the first 

 cirrus is smaller than the others; the longest are on 2 to 6 following 

 segments, but continue long on 8 or 9 moi"e; shorter ones occur 

 irregularly on more or less of the other segments of the anterior half 

 of the body, but rarely on the posterior half; the length of these 

 is scarcely greater than the diameter of the body. 



A transverse group of longer and distinctly larger cirri or tentacles 

 occurs on the 4th setigerous segment, arising from the dorsal sur- 

 face, about 3 on each side. 



The setae of the anterior 6 or 7 segments, both dorsal and ventral, 

 are very slender, capillary, acute, in small fascicles; they are about 

 equal to ^ the diameter of the body. Spiniform set«, bent in a 

 sigmoid curve, begin to replace the capillary ones in the ventral 

 fascicles on the 8tli segment, and increase in number farther back, 

 till they nearly or quite replace the slender setae. In the upper fas- 

 cicles longer, more slender, nearly straight spines gradually replace 

 the capillary setae, but one or two of the latter persist nearly or 

 quite to the end of the body. Posteriorly there ai-e usually, in the 

 upper fascicles, 2 or 3 spines and 1 or 2 capillary setae; in the lower 

 ones, about 3 curved spines, larger than the anterior ones.
