of the Yirginian Coast. 29 
above, flat below ; width of the first fourteen segments 
uniform, after the 14th decreasing gradually to the minute 
terminal one. 
The Ist, 2d and 3d segments are short ; 4th and 5th 
equal in length and width ; 6th to 14th, inclusive, length 
double the width; after the 14th, they become gradually 
shorter, the last ones being very short and crowded. 
Color: general color of body yellowish-white. Anten- 
nae, front of head and all cirri, white. Posterior part of 
head and first segment (in one case the second also), dark 
brownish-red. Between the eyes there is a narrow band, 
extending back to the middle of the first segment, of a 
darker shade than that of the head generally ; and from 
the posterior eyes, on each side a similar line runs back to 
the third segment. Bands of the same color as the head 
cross the posterior part of the following segments (extend- 
ing to the ventral surface, but not crossing it), viz: from 
the 3d to the 11th inclusive, 14th, 17th, 20th, and on every 
fourth segment after the 20th, except that the last three 
are on consecutive segments, and not well marked. On 
the anterior part of the body the width of these bands is 
about one-half the length of the 4th segment. As the seg- 
ments shorten, after the 14th, this band also grows narrow. 
The lower surface of the base of the dorsal cirri, after the 
7th, has a spot of the same color. 
The movements of this species are peculiarly slow, the 
direction of its feet and setae are such that it seems to walk 
on the tips of its setse. 
Length of specimen described, 11°'°'; greatest diameter, 
1 mm 
Number of segments, 80. 
Length of head and first 14 segments, 5°"°. 
On one specimen (lost before the examination was 
finished) a new head was forming back of the 14th segment.
