The White Sea-bass 31 
Jorgas Bay there is a very high tide, and behind 
the flood follow the schools of white sea-bass 
which have been named by Dr. Gilbert after Mr. 
Marshall Macdonald, United States Commissioner 
of Fish and Fisheries. The marked difference 
between the two fishes that would be noticed by 
the angler appears to be that in the latter the 
snout is sharp, while in C. xodzls the head is 
long, snout long and sharp. In C. macdonaldi 
there are about fifty-five pores; in zodzlis, seventy 
or eighty. 
The Gulf bass is the giant of its tribe, and 
can be found in vast numbers on the shores 
of the east coast, even entering the mouth of 
the Colorado River. The young are dusky and 
silvery, and instead of stripes, as in odzlis, have, 
according to Dr. Gilbert, “coarse black specks 
along the lower part of the head and sides,” 
there being no disposition to form streaks or 
bands. It is caught at San Jorgas Bay in April 
and May, and according to Dr. Gilbert is not 
known at Guaymas in summer, having probably 
migrated far up the Gulf, where vast schools 
of mullet afford an ample food supply. The 
angler who desires to take this fish will find 
San Jorgas hot in summer, but pleasant in the
