Geographical Distribution of Umbellularia. 313 
Umbellularia Thomsonii, Kéll., was found in the Atlantic 
three times :— 
1. Between Cape St. Vincent and Madeira, in lat. 35° 20! N., 
long. 1344° W., at a depth of 2125 fathoms. The speci- 
men is the largest that has been found; length, according to 
Kdlliker, 89°5 centims. 
2. 300 miles to the eastwardof St. Paul’s rocks, lat. 1°47! N., 
long. 24° 26' W., at a depth of 1850 fathoms. This is the 
smaller specimen which was sent to Prof. Kélliker, who says 
it has a length of 27 centims. 
3. On the coast of Brazil, off the mouth of the San Fran- 
cisco river, lat. 10° 11’ S., long. 35° 22! W., in 1600 fathoms. 
A half-grown specimen. 
In the Antarctic sea we brought up five times different 
stages of an Umbellularia which is very much like the 
Atlantic species; but whether it is the same or not could 
not be decided, as the specimens of the latter had already 
been sent to Europe. ‘The Antarctic species was found in 
the following localities :— 
1. Halfway between Prince Edward’s and Crozet Islands, 
lat. 46°46! 8., long. 45° 31! E., at a depth of 1375 fathoms. 
A half-grown specimen. 
2. 84 miles to the westward of Hog Island (Crozets), lat. 
46° 16' S., long. 48° 27’ E., at a depth of 1600 fathoms. A 
full-grown specimen of nearly the same size as the first one 
found in the Atlantic. 
3. Near the ice-barrier, lat. 62° 26’S., long. 95° 44’ E., at 
a depth of 1975 fathoms. Several very small and middle- 
sized specimens, some of which will be described hereafter. 
4, On our way from the ice-barrier to the north, lat. 53° 
55! S., long. 108° 35’ E., at adepth of 1950 fathoms. Rather 
small specimens. 
5. South of Australia, lat. 42°42'S., long. 34° 10' E., at a 
depth of 2600 fathoms. Middle-sized specimens. 
We also found an Umbellularia in the Pacific, at a depth of 
2440 fathoms, to the south-west of the Louisiade archipelago, 
where two specimens were brought up, which very likely are 
different from all those which we got before, as the polyps 
appeared to be more flattened, wider, and shorter. 
During our cruise through the Malayan archipelago none 
of these Pennatulids came up. 
According to these data, Umbellularia was never found by 
the ‘Challenger’ in such comparatively shallow water as that 
in which it has been obtained off the coasts of Greenland. 
In the neighbourhood of the Antarctic islands it was often 
found in very deep, never in shallow water.
