August 11, Monday. 
Spent forenoon getting yesterday's stuff in shape. In afternoon stayed 
in moat till dinner time, between 1:30 and 4:30 actually in moat in skiff. 
Found that Cassiopea rarely swimsj is usually upside down in sand. Looks 
all the world like bushy hydroid or alga. Got several Dromias, Lygias, and 
Sesarma, taken from under shoals in "five foot" channel N. of Bird Key reef. 
Found no traces of Calappa, though looked hard. Charley said he only noticed 
large one he got some days ago because it was but half buried.
