these Algz are almost the only source of food for the brine- 
shrimp, as they are diffused through the water in nearly equal 
abundance with the Crustaceans themselves, and in no case that I 
could see, grow attached to any objects in the lake or on the 
shore. The most common form is a rounded mass which lives 
suspended in the water. 
Specimens of the Algæ collected were sent to Prof. W. G. Far- 
low, of Harvard University, from whom the following preliminary 
report has been received : 
“The Algz which you collected in Salt Lake are very inter- 
esting and, as far as I know, are the first which have ever been 
collected in that locality. Mr. Sereno Watson, the distinguished 
botanist of the King Survey, tells me that he examined a portion 
of Salt Lake for Algæ but without success, and thinks it probable 
that very few plants will be found in the lake. The specimens 
you sent comprise two small packages of dried material and a 
small bottle of alcoholic specimens. The alcoholic material is 
scarcely determinable, as the specific characters of Algze, such as 
would be expected to occur in Salt Lake, are generally lost by 
immersion in alcohol. The dried material I have soaked out 
and examined : 
“It consists largely of grains of sand and remains of small ani- 
mals, mixed with which are three species of Algae. The most abun-

using the word in the extended sense adopted by Le Jolis, which 
is in fragments, so that one can form no very accurate id 
habit. The microscopic characters, however, show th 
with scarcely any doubt, Ulva marginata Ag., found on the coast 
Jolis to be the species described by Agardh. The third Alga
