308 PROFESSOR W. A. HERDMAN ON THE 
The Dorsal Tubercle has its long axis antero-posterior and its opening at the side. 
The horns form two close spirals, both coiled inwards. Whether P. patagonica of 
MicHAELSEN is also the same species as P. horrida is very doubtful. I am inclined to 
regard it as distinct.

Locality.—Station 118, on hulks, Stanley Harbour, Falkland Islands, about twenty — 
specimens ; and eight specimens from 6 fathoms, Port Stanley, February 2, 1904. 
There are over two dozen specimens of this species in the collection, and they range 
in size from 1°5 to 7 cm. in greatest length of body—about the same range as in the 
case of those in the Challenger collection. All of these specimens of B. legumen belong 
to the “forma typica” of MicHaELSEN’s system ™ of subdivision of this species, and — 
agree in character with the Challenger specimens from the same locality. In some 
cases the little bristles on the surface of the test are more abundant and more prominent 
than in others, but there are all gradations between. ‘This is evidently a very common 
Ascidian in shallow water at the Falklands. 
Fungulus antarcticus, n. sp. (Plate, figs. 15 to 18.) 
A single specimen which clearly belongs to the rare and interesting genus Pungulus 
was obtained at Station 301 from a depth of 2485 fathoms, on March 13, 1903, at 
lat. 64° 48’8., long. 44° 26’ W.; temp. 31°°02. The genus was established in 1882 for 
another solitary individual found in the Southern Ocean during the Challenger Expedi- 
tion, at Station 147, between the Cape of Good Hope and Kerguelen Island, lat. 46° 
46’ 8., long. 45° 31’ E.; depth, 1600 fathoms, on a bottom of Globigerina ooze. The 
two localities are thus nearly 3000 miles apart, but agree in that both are in the far 
south and in very deep water. 
The Scotia specimen, although closely related to the Challenger Fungulus cinereus, 
Herdman, cannot be placed in the same species. The general appearance and anatomy, 
and especially the remarkable structure of the branchial sac, are the same; but the 
relation of the peduncle to the apertures and the details of structure are different in 
the two forms. The description of /. antarcticus is as follows :— 
The body is club-shaped (fig. 15), like a rounded knob about 1°5 em. in diamete: 
on the summit of a short, stout peduncle, which is also about 1°5 em. in length a 
from 4 to 6 mm. in thickness. The peduncle is continuous with the ventral edge o 
the body, while the dorsal edge projects markedly. The surface is smooth and the
