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 111111 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 seta?; the following ones have a fascicle of long, slender ones, 

 equal to the breadth of the body. 



SYLLIS, species undetermined, (p. 453.) 



A single specimen from Vineyard Sound. The body is about 12 mm 

 long; the antenna? are not very long; the palpi short; the dorsal cirri 

 are rather long, and, like the antenna^, regularly beaded ; the ventral 

 cirri are small, tapering; the seta? 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.
