ongitude. The last
pintado left us 240 miles within the tropics to follow an outward-bound
vessel. Another petrel much resembling it--a new species with longer
wings and different markings, the head, neck, and upper surface being
dark chocolate, and the lower parts white--was abundant between the
latitude of 46 and 40 degrees South, and between the parallels of 36 and
35 degrees South, Procellaria conspicillata was numerous, but
unfortunately I had no opportunity of procuring specimens of either.

Five days after leaving the Falkland Islands, we encountered a very heavy
gale, commencing at south-east, and blowing hardest at east, when the
barometer was down to 29.264--next day the wind went round to the
south-west and moderated. From the latitude of the entrance of the River
Plate up to latitude 15 degrees South, we experienced northerly winds
between East-North-East and West-North-West, after which we got winds
commencing at South-West and merging into the South-East trade, which we
may be said to have fairly got in 13 1/2 degrees South latitude and 23
1/2 degrees West longitude, and lost in 6 degrees North latitude, and 22
degrees West longitude. We picked up the North-East trade in latitude 13
degrees North and longitude 24 degrees West and carried it up to latitude
29 degrees North and longitude 37 1/2 degrees West. I mention these
particulars as the limits of the trade-winds as experienced by us were
considered to differ considerably from what was to be expected at this
season of the year. Gulf weed made its first appearance in latitude 24
degrees North and longitude 35 1/2 degrees West but in small quantity,
and was last seen in latitude 38 degrees North and longitude 33 1/2
degrees West in detached pieces, mostly dead. About 31 1/2 degrees North
and 37 3/4 degrees West it was very plentiful, occurring in long lines
from one to fifty yards in width, extending in the direction of the wind.
Some pieces which were hooked up furnished on being shaken numbers of a
minute univalve shell (Litiopa) many small fish--especially pipe-fish
(Syngnathus) and numerous crustacea (of which Planes minuta was the most
plentiful) while several delicate zoophytes were encrusted or attached to
the weed. In short each little patch of gulf weed seemed a world in
itself, affording the shelter of a home to hundreds of minute and
wonderful animals.*

(*Footnote. The gulf weed is still regarded as of questionable origin.
