135 FISHES OF SINALOA 507 
SUPPLEMENTARY NOTE ON THE FISHES OF LA PAZ HARBOR. 
Mr. James A. Richardson, a member of the Hopkins 
Expedition, spent two days at La Paz, the chief city of 
Baja California, where he made a small collection of fishes. 
The work was done under very unfavorable conditions, as 
La Paz has no fish market and its fish supply is obtained 
by the spear and the hook and line. There is but one 
seine at La Paz, a very old and rotten one, which was 
rented by Mr. Richardson, as was also a parachute seine 
and a small dip-net. Considering all the difficulties en- 
countered, the list here given shows that the locality is 
well worthy of a detailed exploration. 
Concerning the harbor of La Paz, Mr. Richardson has 
the following notes:

large islands, uninhabited, wild and precipitous. The en- 
trance to the estuary is very wide, apparently ten or fif- 
teen miles, the general direction being north and south 
and the length of the estuary about fifteen miles. The 
estuary gradually narrows to about one mile at ten 
miles from the entrance. As the steamer proceeds up 
the estuary it is noticed that she hugs the left bank 
closely. I was told that in all that breadth of water there 
is but a very narrow channel, the balance of the space in 
the estuary being of a sand formation, the sand bars com- 
ing very near the surface of the water so that they can 
be seen from the deck of the steamer. The steamer in 
following the channel nearly doubles on itself occasion- 
ally, and in the darkness of the night a boat is lowered 
and a search is made for certain buoys. The left bank 
is made up alternately of gravel beach and abrupt cliffs 
all the way to La Paz. The country behind La Paz is 
hilly and mountainous, of no value, covered with rocks 
and cactus. The right bank opposite La Paz, as far as
