ova. This species was obtained nowhere else. (iii.) At the next 
station (147), near the Crozet Islands, two specimens of Lagisca cro- 
setensis, M‘Int., were dredged. This species, which in appearance 
resembles a narrow Aphrodite, also occurred at no other station. 
(iv.) Nothria abranchiata, MTnt., Owvrurprs, is, as its name implies, 
remarkable in the genus by having no branchie, and, like so many 
of its deep-sea companions, no eyes. It was dredged both in the 
Antarctic, station 156, and “in the middle of the Atlantic, north of 
Tristan da Cunha.” It is characteristic of this deep-sea form to have 
much larger bristles than its congeners. The tubes in which it lived 
were flexible, coated with a grey mud, Diatom ooze, and strengthened 
by a long, moniliform, brown, arenaceous Foraminifer. The tubes of 
the northern form were strengthened by Spatangoid spicules, and the 
shells of a rare Dentaliwm, of Aporrhais, Bulla and Terebratula, and by 
one of the valves of a Cirripede. The intestine of the Antarctic form 
contained the chitinous cuticle of numerous small Crustacea enveloped 
in Pteropod ooze. Another species of the same genus, founded by 
M‘Intosh on a fragment of the anterior region of the body, is Nothria 
armandi, M‘Int., dredged at station 157, about half-way between 
Kerguelen and Melbourne. It is without eyes. Its tube was friable 
and composed of Diatoms and Radiolarians. (v.) Hyalinecia bentha- 
liana, M‘Int., belongs to the same family, and was taken at the next 
station (158). One specimen only was dredged, but “ what appears 
to be the same form” was taken a little west of the Northern Island 
of New Zealand. Its tube is chitinous and semi-transparent. (vi) 
At the station 156, and nowhere else, several specimens of Ephesia 
antarctict, M‘Int., belonging to the family Spaxroparmx, were 
dredged. This species is an unusually large and muscular example 
of the genus. (vil.) Zrophonia wyvillei, M‘Int., representing the 
Cuatorzemix, was found at 1950 fathoms, at station 157, an unusually 
rich spot for Annelids. But a single specimen was dredged. This 
species is one of the largest and most characteristic of the genus, and 
is an interesting example of what was at one time regarded as a 
littoral family. To the morphologist this genus is noteworthy on 
account of its looped alimentary canal, its single pair of nephridia, 
and the presence of but two septa. 
The family Maroavio.x (Ciruxvivz) is represented by the genera 
Maldanella and Praxilla, The Challenger first showed that members 
of this family descended to great depths. “In regard to food, no 
group shows more strikingly the value of Diatoms, Radiolarians and 
Foraminifera, as the original food producers for fishes and the higher 
forms. These groups constitute the chief nourishment of the deep-
