AUTOLYTUS, species undetermined. 
Females, filled with eggs, of a large species of this genus were taken 
at the surface of Vineyard Sound, April 30, by Mr. V. N. Edwards. 
These were about 40™™ in length, as preserved in alcohol, and rather 
stout, tapering to each end. The head is small, short, rounded in front. 
The eyes are small, and the two pairs are near together. The odd 
median antenna is more than twice as long as the breadth of the head; 
the lateral ones are about half as long; the first six setigerous segments 
have short set; the following ones have a fascicle of long, slender ones, 
equal to the breadth of the body. 
SYLLIS, species undetermined. (p. 45.3.) 
A single specimen from Vineyard Sound. The body is about 12™™ 
long; the antenne are not very long; the palpi short; the dorsal cirri 
are rather long, and, like the antenne, regularly beaded; the ventral 
cirri are small, tapering; the sete are numerous, rather short. 
GATTIOLA, species undetermined. (p. 453.) 
Young specimens were taken several times in Vineyard Sound, at the 
surface. ‘Adult specimens of a fine species of this genus were dredged 
in the Bay of Fundy in 1872, in 80 fathoms.
