Fort Jefferson moat, from Halimeda July ;25, 192^ 
Numerous small colorless shrimps brown (faint bistre) or greenish (faint 
chromium green) spotted with 
possibly olive buff in color 
Any number almost can be washed from bunches of Halimeda. Were dead when 
washed out in laboratory. 
Two in separate tiny vials are transparent in life, both with opaque white 
specks or rather spots scattered over^fch the body, especially aggregated over 
alimentary tract on carapace on eyestalks, and antennular peduncles, a few 
on antennal scales. The one is clear as glass but for white spots which more 
or less (alone in a dish) reveal its presence, under a glass the frontal 
margin of carapace 
region except restrum, and ant. first and second appendages and stomach pcx 
region is faintly tinged with merest touches of parrot green; a few widely 
scattered olive green chromatophores on abdominal epimera. Legs transparent 
A . 
with few white spots along them.

The other is similar except on carapace there are a few faintly olive 
green chrematophores and on the abdomen a few olive ones, but enough in each 
case to give the animal quite a dark appearance though it can still be seen 
to be iranx more transparent than otherwise. Eggs of this specimen colored 
faint greenish brown like body, especially abdomen not noticeable in life.
