The following notice is derived from the 
remarks of Lieutenant Commander M. Sicard, 
commanding U. S. S. Saginaw, I860. 
(All Bearings are Magnetic. Variation 
8- 30' Easterly in 1870.) 
Richmond rock. The position of this 
rock, reported to lie about 15 miles W. by 
S. ’ S. from Cape Corrientes, was passed 
over by Captain G.F. Emmons, of the ILS.S. 
Ossipce, in April 1868: tlie weather being clear, 
sea smooth, with a westerly swell, and a good 
look-out kept, but no indications of shoal 
ground were observed. The rock was also 
carefully but unsuccessfully searched for by 
the Saginaw in August and September 1861). 
The pilots and coasters in the neighbourhood 
do not believe in its existence. 
Cucharitas reef, a dangerous ledge ex 
tending to the south-west nearly 2 miles from 
the coast, lies about 6 miles to the southward 
of Cape Corrientes. The part above water 
projects from the land south-west for about 
1| miles, and consists of 3 or 4 small rocks, 
against which the sea breaks heavily, and 
also for a considerable distance outside tltem. 
Two other sunken reefs are reported to lie 
half a mile to the south-west of the rocks 
above water. The land near this part of the 
coast is low. but rises again at a short distanco 
from the beach.
