The following afternoon found us at anchor off Cedros Island, Lower 
California* In a comparatively short time 37 fish were secured by the fishing 
parties, besides some 200 others which were taken over the side by members of 
the crew using hand lines. Among these was numbered a 120-pound black sea 
bass or jew fish caught on a light 20-pound test line. Although groupers and 
sea bass of several species were plentiful, California yellowtails formed an 
important part of the day's catch in the fish-boats. Some fossils from an 
outcrop near the landing place on the east side of the island and a number 
of species of littoral marine life were secured by the collecting party on 
shore* 
The next three days in succession were spent at Magdalena Bay, July 
IS; oft Punta GorGa, Cape pan Lucas, July 19; and Socorro Island, July 20.

sandy, weedy bottom of the Bay, inside the entrance to the northward, in 10 
to 15 fathoms, an almost incredible number of amphipod crustaceans were dis-

to the laboratory aboard the HOUSTON became covered with a thick film or "scum"

they must have been literally as numerous as the grains of sand on the bottom. 
I have never seen so many amphipods in one place before. Our Museum amohipod 
specialist, Mr. Clarence R. Shoemaker, was moved to make the same remark 
when he was presented with more than a solidly packed quart of them. It was an 
amazing sight.

San Iaicas extends the range of this species southward on the west side of the 
Gulf of California below Cerralvo Island, south of which it had not been taken
