POLY CHADTOTJS ANNELIDS OF THE HAWAIIAN ISLANDS. 
1181 
Somites 2 to 5 carry dorsally a row of short, stout setae with broad pointed ends (fig 80). Whole 
surface of expansion covered with short, sharp spines. Alternating with these in each row are very 
long, delicate hair-like setae. On sixth somite these setae disappear and a row of uncini takes their 
place. Each uncinus with numerous sharp spines along one face, looking in profile (fig. 81) like a 
single row of very sharp spines. Some show a rod attached at one end as in figure, while in others it 
is attached at the opposite end. I am unable to say whether there is any regularity in the distribution 
of these two forms. These rows of uncini are found in as many somites as were preserved in any of 
my specimens. Ventrally in each somite is a tuft of very long, hair-like setae. 
The posterior body region was not preserved in any of the specimens. 
Tube very thick walled, composed almost entirely of shells of foraminifera. 
Length of head and 12 anterior somites 16 mm. Width of anterior region 3.5 mm. Color (in 
alcohol) light brown ventrally, dark brown dorsally. Palps and cirri of head very light brown. 
Paleae golden yellow. Collected at station 4041, 382-253 fathoms, on bottom of gray mud and fora- 
minifera. Type no. 5224, U. S. National Museum.
