the posterior end. Head often somewhat expanded, a little flat- 

 tened, obtuse or subacute in front according to state of extension. 

 Ocelli form, on each side of head, a nearly simple submarginal row- 

 on the antero-latei'al part, and beliind the ends of each of these 

 rows there is a small cluster of about three or four ocelli on each 

 side, near the ganglions. 



Color dull white, grayish, or pale flesh-color, often with a darker 

 stripe along the back due to the proboscis-sheath; along the margins, 

 especially beneath, the lateral sacs of the alimentary canal are 

 often visible. Length 50 to 75"'™; diameter 4 to 6'"'", in extension. 

 Eastport, Me., and Grand Menan, N. B., at low-water mark, under 

 stones. 



This species, which is here referred, with some doubt, to the 

 European form, is not uncommon on the shores of the Bay of 

 Fundy.

Body rather stout, not much elongated, tapering somewhat to 

 both ends. Head usually broader than the body, ovate in exten- 

 sion, obtuse in front, separated from the body by a slightly marked, 

 curved, transverse groove or fossa on each side. Ocelli numerous, 

 arranged somewhat in four groups, the anterior pair lateral or sub- 

 marginal, the posterior subdorsal; the anterior clusters form long, 

 crescent-shaped groups or nearly simple rows on each side, running 

 somewhat parallel with the antero-lateral margins of the head, but 

 curving inward posteriorly, so that their posterior ends nearly meet 

 on the median dorsal surface; the two posterior groups, which are 

 opposite the hinder portion of the crescents and nearer the postero- 

 lateral margins of the head, have an irregular I'oundish or ovate
