ABYSMAL FAUNA. 257 
depth of 1500 fathoms downward. In both cases the number of 
specimens was small, as is the number of species when compared 
with similar “takes” in shallower waters. 
The following were taken, at a depth of 1375 fathoms, between 
Prince Edward Island and the Crozet Islands:—(i.) Cythere dasy- 
derma, Br., station 146, and in many other places, and (ii.) 
C. acanthoderma, Br., at the same station, and elsewhere. These two 
species appear to be cosmopolitan in all deep seas, but they have not 
been taken at less depths than 580 fathoms. (iil.) C. dictyon, Br., 
which usually ranges from 1000-2000 fathoms, but has been taken 
in waters as shallow as 120 fathoms. Taken at stations 146 and 150, 
and elsewhere. It is a variable species, and seems to be ubiquitous in 
deep waters. (iv.) C. viminea, Br., taken at station 146. (v.) Krithe 
producta, Br., a cosmopolitan and, apparently, a very variable species, 
taken at station 146, and elsewhere. Many other species were taken 
in the tow-net and in dredgings down to 150 fathoms in these waters, 
but the above five represent the deep-sea Antarctic forms. 
Order II.—Coprpopa. 
The only undoubted deep-sea Copepod is Pontostratiotes abyssicola, 
Br., which has been dredged up in the mud from a depth of 2200 
fathoms, but not in our area. Calanus princeps, Br., Hemicalanus 
aculeatus, Br., Phyllopus bidentatus, Br., and a species or two of 
Eucheta, have some claims to be considered abysmal, but none of 
them have been recorded from the Antarctic region. 
Order III.—CiIrRIPEDIA. 
Of the Cirripedes taken by the Challenger in Southern latitudes, 
Lepas australis, Darw., was found floating on seaweed near Prince 
Edward Island. According to Darwin this species is common on 
Laminaria throughout the whole Antarctic Ocean. To this ocean it 
is confined as far as our knowledge goes. It is, of course, not a 
deep-sea form, but worth mentioning as peculiar to the Antarctic. 
(.) Scalpellum carinatum, Hoek, was described from specimens taken 
near Tristan da Cunha from a rocky bottom some 1000 fathoms 
deep. No complemental male was found. (ii.) Se. africanum, Hoek. 
(ii1.) Se. ecimium, Hoek, and (iv.) Sc. elongatum, Hoek, are from the 
same locality. (v.) Se. recurvirostrum, Hoek, was taken between 
Heard and Kerguelen Islands at a depth of 150 fathoms. Again no 
complemental males were found. (vi.) Se. brevicarinatwm, Hoek, a 
typical deep-sea Cirriped, was taken at stations 146 and 147. These
