OBTAINED DURING THE CRUISE OF H.M.S. ' VALOROUS.' 501 



much larger examples occur in my collections from Exeter Bay, Greenland. Some 

 varieties approach Lvarne, but there is no difficulty in discriminating them. 



Evapne impar, Johnston. Station 4, 20 fathoms ; Station 6, 64° 5' N., 56° 47' "W., 

 410 fathoms, in sandy mud ; Holsteinborg Harbour, in 10 fathoms ; Godhavn Harbour, 

 5-20 fathoms, 



Eupolynoe occidentalis, M°I. Station 1, 175 fathoms, in sandy mud. The frag- 

 mentary specimen has scales, which were absent in the Canadian example *. In spirit 

 these have a ferruginous-brown hue, and the surface is almost smooth, the minute 

 spines being insignificant. On the outer border they have rather numerous, long, slender 

 cilia (PL LXV. fig. 1), the tips of which are very slightly dilated. Parasitic Pedicellinm 

 abound on the bristles. The Lepidonotus sublevis of Prof. Verrill f may be this or an 

 allied form, but his description is too lax for determination. 



Eusthenelais abyssicola, n. sp. Station 16, in the middle of the North Atlantic, 

 55° 10' N., 25° 58' W., in 1785 fathoms, on a bottom of Globigerina-ooze. This is repre- 

 sented by a minute and fragmentary example, which at first sight was considered to be 

 a Leanira. In Sthenelais and Sigalion the ventral bristles are more or less boldly 

 bifid ; in JEusthenelais, while the bristles lean to the former types in regard to terminal 

 segmentation and outline, yet many have perfectly tapered tips without a trace of the 

 secondary process. In the present form every one of the inferior bristles (PL LXV. 

 figs. 2 & 2 a) has a filiform tip, but the upper group (fig. 2) more nearly approach the 

 characteristic terminal portions in Leanira ; it needs but the shortening of the tips of 

 the processes and the better definition of their transverse markings to convert them into 

 those of an ordinary Leanira, for the same gradation between the superior and inferior 

 series of the ventral bristles is maintained in that group. Moreover, the steps 

 between Sigalion and Sthenelais on the one hand, and Leanira on the other, are 

 further indicated by the diminution of the serrations on the distal end of the shaft of the 

 bristle, such being distinct in JEusthenelais hibernica J, very rudimentary in the present 

 form, and altogether absent in Leanira. 



The injured fragment is devoid of scales and is eyeless. The palpi resemble those of 

 JEusthenelais hibernica ; the tentacular cirri (and probably the tentacle also) are short. 

 A few lobate papilhe occur on the feet, as in the last-mentioned species, and the ventral 

 cirrus does not seem to reach the tip of the setigerous division. 



Pholoe mintjta, Fabr. 7-10 fathoms in Holsteinborg Harbour; 5-20 fathoms in 

 Godhavn Harbour. The specimens are large. 



Nephthys ceca, Eabr. Station 4, 20 fathoms, on shell- sand ; 10 fathoms in Hol- 

 steinborg Harbour ; 5-20 fathoms in Godhavn Harbour. Many Infusoria are attached 

 to the bristles. 



Nephthys ciliata, O. P. Miiller. Station 1, 175 fathoms, off Hare Island, Disco, in sand 

 and mud ; Station 3, 100 fathoms, in sandy mud ; 10 fathoms in Holsteinborg Harbour, 

 5 to 20 fathoms in Godhavn Harbour, Disco. Swarms of a commensalistic form, re- 

 sembling at first sight a little Leech, occur between the feet, and quite differ from similar
