5. The drag nets or dredge which we used with such 
success at Magdalena Bay was again employed on July 19th, during 
our stop off San Jose del Cabo, in the vicinity of Punt a Gorda. 
Among the various forms of marine life brought up were several 
spider* crabs of e species unknown to rae . I have not been able 
to determine with the aid of a comprehensive treatise, on 
American crabs published by the Museum which I have thought 
along for the purpose of identifying, the crabs we might take.

red shiimp they had discovered in the suction side of one of 
the condensers opened for minor repairs. It was a galatheid 
.very common in Lower California waters, at least at 
. seasons. At times they occur in such countless numbers 
color the water red for great distances. Huge windrows 
the dead shells of these animals have been observed in the 
as a conspicuous red straak^&long the shore line. 
Crustaceans of this type form an important whale food and 
without doubt this species played an important part in the 
former abundance of whales in the Lover Californian and Mexican 
waters. A large black sea bass taken in Magdalena Bay during 
the day regurgitated several of these galatheids when hauled 
into the boat.

\ 6. At Socorro Island, July 20th, both shore collecting 
and dredging was accomplished. The most interesting animals 
secured this day were several specimens of burrowing shrimp. 
These were found in passages they constructed in the muddy sand 
under boulders forming the greater extent of the shore at the 
landing place. one of the men in the landing party discovered 
a crude cross atop a large mound. Upon the cross appeared to 
have been painted, in Spanish, "To the memory of the sailors — 
March 8, 1924". The lettering was almost illegible as the 
result of weathering. 
7. July 21st, an eventful day. A landing was made at 
Clipperton Islandi This isolated coral atoll, the only one in 
Pacific American waters, has seldom been visited by scientific 
parties chiefly because of the difficulty of landing on its 
surf -beaten shores and the uncertainty of weather conditions in 
that area.
