226 Prof. M‘Intosh’s Notes from the 
ridges in some examples. The terminal process is obliquely 
striated, of moderate length, serrated on the edge, and finely 
tapered. 
The ventral lamella is bluntly rounded at the tip in front 
and broadly ovate. It projects considerably beyond the seti- 
gerous region both in the anterior and posterior feet, but it is 
narrower and more pointed externally. 
A specimen had thrust itself into the tube of Chetopterus. 
Unfortunately Prof. Verrill does not mention the condition 
of the proboscis or the ventral lamelle in his species *. 
Accordingly his Hteone robusta, E. limicola, and E. setosa 
cannot be accurately identified. 
Eteone cinerea, Webster & Benedict ? 
Habitat. Dredged by Mr. Whiteaves between Bradelle 
Bank and Miscou Island, in 45 fathoms, Gulf of St. Lawrence, 
Canada. 
Head forming an obtuse cone, brownish, and without 
visible eyes. The tentacles are short. The subulate tenta- 
cular cirri are a little longer than the feet, and about four 
seem to be present on each side, thus differing from the 
typical Hteone. 
Body incomplete, about three-quarters of an inch of the 
anterior region being present. It 1s tinted brownish in front, 
pale posteriorly. ‘The aspect from the dorsum is peculiar, 
since the elongated dorsal lamella trend backwards as isolated 
TOCESSES. 
The 30th foot (PI. I. fig. 4) has dorsally a lobe which, at 
the 10th foot, is ovato-lanceolate, and although the pedicle is 
short it extends far outward and upward from the setigerous 
process. It increases in size posteriorly, and the pedicle 
becomes more distinct, the lamella forming an elongate ovoid, 
slightly narrowed at the tip, yet presenting a more or less 
clavate aspect in certain views. In form the dorsal lamella 
somewhat resembles that of Ehlers’s Mteone sculpta tT from 
South Georgia, but in this case it is considerably longer, and 
there are other differences in the structure of the feet. The 
setigerous process is short and bifid. ‘The shafts of the pale 
slender bristles have an elongated or somewhat fusiform 
dilatation at the tip, and the spines at the end are delicate 
and translucent, but have a similar arrangement to that of 
Eteone. ‘he dilatation is very minutely spinulose. The
