MARINE INVERTEBRATA OF GRAND MANAN. 33 



OPHELIA GLABRA, St., n. s. Body robust, smooth and shining, tapering at both 

 extremities, flat or even concave below. Posterior extremity with two large infe- 

 rior papillae, and eight small superior ones. Lateral cirri short and thick ; about 

 twenty pairs, on the middle and toward the posterior part of the body. At their 

 bases are two approximated bundles of capillary setoa, which extend anteriorly as 

 far as the mouth where they are very minute on the broad smooth rings and to 

 the anus posteriorly. Color, light fawn, with iridescence. Length, 1.5 inch; 

 breadth, 0.25 inch. Dredged on muddy bottoms in deep water. 



ARICIA QUADRICUSPIS, (?) Grube. Scoloplos quadricuspida, Oersd., Gronl. Ann. 

 Dors., pi. viii. f. 110. The small specimen taken was too much injured for cer- 

 tainty of reference. 



GLYCERA CAPITATA, Oersd., Gronl. Ann. Dors., 44, pi: vii. f. 88. Of a pale flesh 

 color. Found at low-water mark under stones on sandy shores. 



G. VIRIDESCENS, St., n. s. This species is much smaller than the preceding, being 

 only one and a half inches in length. Its color is light green. Its setae are longer 

 than those of G. capitata, but not so long as those of G. setosa. 



PHTLLODOCE GRCENLANDICA, Oersd., 1. c., pi. ii., f. 19, 21, 22, 29-32. A large 

 bright-green species. It is not uncommon in 25 f., shelly, back of Duck Island. 



NEPHTHYS CILIATA, Miill. N. borealis, Oersd., Maricolae, 32. The specimens 

 found were mostly jet black. Dredged in 25 f. mud, near Duck Island, and in 40 

 f. mud, off Long Island. 



N. INGENS, St., n. s. Resembles N. coeca, Oersd., Gronl. Ann. Dors., 41, pi. vi. 

 73, etc., but is somewhat more slender, and differs in the form of the head, which 

 is rounded anteriorly, truncate behind, and has very short tentacula close together 

 in front. The proboscis has about twenty fleshy teeth at its extremity, and the 

 same number of longitudinal rows of short processes on its sides anteriorly. 

 Length, 7.5 inch, breadth, 0.42 inch. One specimen only was taken, which was 

 dredged by Mr. Wm. Bridges, in deep water. 



NEREIS ABYSSICOLA, St., n. s. Smaller than N. pelagica, Linn., broadest in front, 

 tapering gradually posteriorly. Color reddish, cupreous, darkest anteriorly. Pinnte 

 with four short subequal lobes ; dorsal cirri and seise long, especially on the pos- 

 terior rings. Eyes four, conspicuous ; those on each side being close to each other, 

 while those in each pair are remote from each other. Proboscis with a denticulated 

 basal ring, as in N. denliculata, herein described, except that the papillae above 

 have a circle of denticles instead of being covered with them. The setaa are longer 

 than those of N. pelagica, the tentacular cirri smaller, and the body more tapering. 

 The eyes of the anterior pair also are more distant from each other than the 

 posterior ones. Length, 1.5 inch, breadth, 0.14 inch. In 40 f. mud, off Long Island. 



N. IRIS, St., n. s. Small ; body slender, translucent, bluish, with shades of light- 

 copper color on the back. Neck rather long, palpi large, tentacular cirri long and 

 slender. Differs from N. abyssicola in the want of the long superior cirri on the 

 pinnae, and is also much more slender. Length, 1.6 inch. It was found in a thin 

 leathery tube, encased without with small pebbles. In 20 f., north of Duck Island. 

 N. DENTICULATA, St., n. s., Fig. 23. Body subcylindrical, tapering rather sud- 

 denly posteriorly. Color light reddish-brown, pearly above, nearly white below.
