forms (Loxosomce) occurring in the British species in having a shorter pedicle, with a 

 larger basal portion for attachment, while the tip of the body is bluntly rounded and 

 presents only an aperture on one side. 



Phyllodoce gbxenlandica, (Erst. Station 4, in 20 fathoms, on shell-sand ; Godhavn 

 Harbour, 5-20 fathoms. The large specimens exceed in size those from British waters. 



Etjlalia viridis, O. E. Miiller. 7-12 fathoms, Holsteinborg Harbour. 



Eulalia pboblema, Malmgren. Station 5, 66° 59' N., 55° 27' W., 60 fathoms, on 

 sand and shells. In spirit the specimen is dusky brown dorsally, and the lamellae are of 

 the same hue ; ventrally it is paler. The tips of the bristles are comparatively short, 

 and the enlarged distal end of the shaft finely spinulose. Dr. Malmgren received only 

 a single injured example from the same (western) shores of Greenland. 



Eteone arctica, Malmgren. Station 5, 60 fathoms, on sand and shells. A minute 

 species, in which the proboscis (in the present examples) forms a clavate process, smooth 

 throughout the greater part under a lens, but toward the terminal dorsal region of the 

 partly extruded organ a distinctly papillose area occurs. In some there is a division of 

 the proboscis into a firm basal region and a more membranous distal portion. It seems 

 to come close to E. pusilla, the chief differences between the species, according to Dr. 

 Malmgren, being that in the latter the body tapers equally anteriorly and posteriorly, 

 and the head is longer than broad ; whereas in E. arctica the body tapers less, and the 

 antero-posterior and transverse diameters of the head nearly correspond. The superior 

 lamella of the foot touches the next division in the anterior and central regions of the 

 body in E. pusilla, but is separate in E. arctica. The anal cirri are elongate (linear- 

 fusiform) in the former, broadly ovate in the latter. The condition of the proboscis in 

 E. pusilla is not noticed. In the present form the inferior lamella is not longer than 

 the bristle-papilla. It was formerly procured in Spitzbergen and Finmark. 



Eteone plava, Eabr. 5-20 fathoms, Godhavn Harbour, Disco. 



Ancistrosyllis grcenlandica*, n. sp. A remarkable form, apparently allied to 

 the SyllidaB, was dredged at Station 6, 64° 5' N., 56° 47' W., in 410 fathoms, on 

 a bottom of sandy mud. The specimen is about f of an inch long. The head 

 forms a short blunt cone, divided by a somewhat shallow fissure into two frontal 

 lobes (PI. LXV. fig. 20), each of which has a short tentacle at tbe base, while 

 toward the posterior border another short conical tentacle occurs in the middle line. 

 Immediately below the great lateral eye on each side are two somewhat larger 

 tentacular processes, which resemble those on the adjoining segments of the body. 

 The latter is slightly tapered anteriorly, and more distinctly so posteriorly. The 

 segments are deeply cut, especially behind the anterior third and for some distance 

 along the wide part of the body. They are 57 in number. Each foot, in the anterior 

 third, has a short dorsal and a smaller ventral cirrus (PI. LXV. fig. 3), a single large 

 and characteristic hook, which somewhat resembles those on the first body-segment 

 of Paramphinome pulchella, Sars, placed above the former, and a slender longitudinally 

 striated bristle (generally enclosed in the tissues). The inferior division bears, in a promi- 

 nent lobe, a spine and a series of simple bristles, with a slight wing on one side — best
