the form described by Prof. Smit (from Florida) as Entalophora 
deflexa .” But there seems to be very considerable doubt as to the 
synonymy or identity of this latter species. 
Membranijpora galeata , Busk. — Described from Kerguelen and 
from the Falkland Islands (Busk, “Bep. Antarctic Exp.,” Trans. 
Roy. Soc., vol. clxviii. p. 195). A form described as var. midtifida 
is recorded both from Simon’s Bay and from the Azores (Busk, 
Cliall. Rep., pt. xxx. p. 64). 
Membranijpora crassimarginata, Hincks. — A variety incrustans 
from Tristan d’Acunlia is identified by Busk with Mr Hincks’ 
species from Madeira, certain differences being noted between the 
two, and also, with a mark of interrogation, with Smit’s M. 
lacroixii from the West Indies. 
Cribrilina monoceros, Busk. — Becorded from Port Jackson, 35 
fathoms; from off Marion Island; from 1325 fathoms in lat. 45° 
31' S., long. 78° 9' W.; from 55 fathoms, lat. 52° 20' S., long. 68° 
0' W. ; from 12 fathoms, lat. 51° 40' S., long. 57° 50' W.; and also 
from 3125 fathoms, lat. 38° 9' N., long. 156° 25' W. 
Platydia anomioides, Scacchi. — Several specimens of this little 
Brachiopod were got by the “ Challenger ” off Marion Island. The 
species was formerly known from the Mediterranean Sea and the 
coast of Portugal. 
Pyrosoma sjpinosum, Herdman. — This species is represented in 
the Challenger collections by a few small fragments only, obtained 
in the South Atlantic 400 miles west of Inaccessible Island, and 
again in the Kortli Atlantic to the west of the Azores. 
In regard to the Tunicata as a whole, Professor Herdman has 
lately expressed his opinion as follows : — “ The Tunicata instanced 
by Dr Murray, both in his * Challenger Summary,’ and in his 
paper on the ‘ Marine Fauna of the Kerguelen Begion,’ help to 
swell lists that assume rather imposing dimensions ; but when I 
examine the case of these species and genera of Tunicata individually, 
I find that the records of occurrence have to be added to or 
modified in such a way as to entirely change the nature of their 
evidence, and show that there is no such close resemblance 
between the northern and southern polar faunas as Dr Murray 
and others have supposed” {Trans. Liverpool Biol. Soc., xii. p. 
251, 1898).
