Family NEREIDiE. 
As in other expeditions, this family was found but sparsely in the Antarctic; 
indeed, until 1908, the only species that had been met with was N. loxechini, which 
Kinberg had originally described from the Magellan Strait, but which in recent years 
has been recorded from the deep water to the east of Island of St. Paul, and from the 
winter quarters of the “ Gauss.” But Elders found amongst the “ Valdivia” worms 
Nereis uncinata from near Bouvet Island. The “ Aurora ” did not meet with it. 
Family NEPHTHYDIDAE. 
In addition to N. macrura, which is a Sub-antarctic form entering the Antarctic 
region, N. abranchiata, has been recorded from the region by Elders (1913). 
Family EUNICIDAL 
The Eunicids scarcely enter the Antarctic, for only two species have ever been 
recorded, both of which are included in the present collection. Lumhriconereis niayal- 
hacnsis is a typically Sub-antarctic form, and only one specimen was gathered in 
Commonwealth Bay. The small pelagic Ophryotrocha claparedi was however 
extremely abundant in Boat Harbour ; it has already been gathered elsewhere, 
though recorded under the title of Paraetius notialis. 
Family GLYCERIDE. 
Glycera capitata, originally described from the European seas, is the only member 
of the family that appears to enter the region under consideration. It has been met 
with by each of the expeditions. 
Family ARICIIDAL. 
Hitherto only three species belonging to the family have been described from 
the Antarctic region. One of these, Aricia marginata, is included in the present col¬ 
lection. A new species, Scoloplos maivscmi, is necessary for a worm that differs from 
S. kerguelensis, which has been recorded by the French Expedition, but which is 
characteristically a Sub-antarctic form. 
Family CIRRATULIDAE. 
The Cirratulids are also very rare in the region ; only one species has been 
definitely determined, though Ehlers found certain worms which he names generically 
without giving specific names to them. This sole species is the European Cinatulus 
cinatus, hitherto known from the Magellan Strait and elsewhere in the south under 
Ehlers’s title, Promenia fulgida, which Fauvel has shown to be a nomen nudun. 
Family TEREBELLIDAL 
The Antarctic is a favourable habitat for members of the family, as each 
expedition adds one or more to the species already known. Of the twenty-four that 
have been recorded the Aurora ” obtained seven off Adelie Land. Of these, three
