Morning, cleaned up previous day's mess of collecting. 
The Xanthids are very hardy. In a tub collected before yesterday noon, in 
which the water had become so stagnant that it had a decidedly bad odor, 
everything, numerous sea anemones were dead on the bottom and all the 
Mithraxes and Squillas, too. The two little Xanthids (Bush Key) and the one 
iscrg lone isopod (the only one I found) were the isugiy only living things. 
Out of Bender's Fort Jefferson dock collections the Acteas and Leptodius 
were the only things alive in the stagnant bucket this morning. They seemed 
dead, too, but revived on being transferred to a dish of fresh water. The 
green, hairless (on carapace) Mithraxes are very hardy, but the Xanthids last 
longer, that is, revive where the others won't. 
In late afternoon, between 3*00 and 5*00 p.m., collected on southern end of 
Bush Key Reef, just north of channel. Got a number of crabs, but nothing new, 
and a carapace of a Calappa. 
Brought back four pieces of seaweed overgrown dead coral, largest 1x2 feet, 
i c 
3 smaller ones about 1 ft.xo in. Some holes inthem. Cr^ked them in tub, 
scraped off xgix algae. From washings got quite a number of Crustacea, in¬ 
cluding another Epialtus, Lysmata, and a GnathophyHum.
