sea and many other Annelids, and the majority would seem to live 
on the spot where they have been swallowed, to judge from their 
appearance in the alimentary canal of the Annelids. 
“The discrimination shown by the family in the formation of 
their tubes is at once apparent in contrasting the mud swallowed as 
food with that composing the tube. Almost invariably the latter is 
coated with the coarser Foraminifera, the larger Radiolaria and the 
rougher sand particles, and this even in instances where there would 
have been no obstacle to the admission of the one as well as the 
other into the buccal orifice.” (viii) Maldanella antarctica, M‘Int., 
was taken at three stations, 146, 152 and 157, inside the Antarctic 
region. Numerous specimens were dredged. With this species, at 
station 157, was dredged another member of the same family, found 
nowhere else, (ix.) Prazilla abyssorwnm, M'Int. The species was 
founded on an imperfect specimen. 
The family Asparcrevip2, remarkable for the paucity of its 
examples, was represented in the Antarctic by (x.) Petéw assimilis, 
M‘Int., taken only at station 147. The genus is interesting because 
it has a coiled intestine. (xi.) Amphicteis wyvillei, M‘Int., a single 
specimen only was dredged at the same station. The alimentary canal 
of this creature contained Globigerina in a fresh condition, showing 
that Foraminifera inhabit the depths of the sea. It is a member 
of the family Ampuarermx, which is further represented in Ant- 
arctic seas by (xii.) Grubianella, a genus described by M‘Intosh from 
Challenger material. G. antarctica, M‘Int., the only species of the 
genus, was taken at the stations 156, 157 and 158, at depths of 
1950-1975 fathoms and 1800 fathoms. M/‘Intosh recognises one 
variety. 
Of the large family Tzrgse1zpx, two genera are recorded, Leena 
and Pista, both represented by a single species founded on a single 
specimen, which, in the case of the last-named genus, was imperfect. 
(xiii.) Leena antarctica, M‘Int., was dredged at station 156, together 
with the Grubianella and the Hphesia of the same specific name. 
(xiv.) Pista abyssicola, M‘Int., was taken at station 157. 
One or two points of general interest in the deep-sea Polycheta 
are perhaps worth mentioning here. The types found in what 
M'Intosh terms the Australian region are “in many cases peculiar 
and novel.” “Comparatively few of the species range into other 
areas, if we except the ubiquitous varieties of Letmonice producta, 
and one or two others. Finally, two species of parasitic Crustacea 
were found on the deep-sea Polychets; one, Trophoniphila bradii, 
M‘Int., adherent to the bases of the branchize, with ovisacs project-
