numerous, arranged in a fan, the upper as long or a 

 little longer than the foot, each lower one becoming a 

 little shorter. All are long. There are one or two (f. 43) 

 aciculse in each foot, which are straight, taper uniformly, 

 and end in a small enlargement (button). The last 6 or 

 8 segments taper slightly ; otherwise the body is of uni- 

 form width. 



The general color of the dorsum is yellowish-white ; 

 feet and sides, white; ventral surface same as dorsal. 

 Between the segments runs a dirty or brownish- white 

 line, and there is a similar line between the bases of the 

 dorsal cirri on each segment. The ground color is inter- 

 rupted by numerous dark brown spots or specks, for the 

 most part arranged in transverse lines. These spots are 

 dark and very numerous on the dorsal and lateral surfaces 

 of the feet. 



Sexual Forms, 



The males and females of this species do not differ 

 much from each other or from the stem form. I did not 

 see many examples of either sexual form, and most of 

 these were mutilated. So far as I was able to determine, 

 the capillary (sexual) setse in the male begin on the 11th or 

 12th segment, and fail on the last 8. They were short, not 

 reaching beyond the feet. This part of the body was 

 slightly swollen ; color, pure white. 



In the female, the capillary setae begin on the same 

 segment as in the male ; they fail on the last 10 segments, 

 are very long, double the length of the feet and ordinary 

 setse taken together. The eggs are brown, and determine 

 the color of this part of the body. The anterior and pos- 

 terior segments have the usual color of the stem form. 

 On all sexual specimens, and on many that could not be 

 determined as such, there is a dark brown crescent at the 

 base of each foot (ventral surface).
