Young Longley got 2 little crabs from among turtle grass this day, two 
small Pitho and one smaller. 
The two Upogebias were found in tube which I have complete all but the 
bend, I'm sure. Female was the only one that was noticed hanging out of 
cracked open burrow when brought me. Two external openings very small, just 
big enough for ventilation. Why the operculum, saved feces for diatom

examination; also have bit ix of lining of burrow examined. This piece of 
bryozoan-encmisted rock was saved separately. Very common among shrimp of 
Callianassid type, these self-immured prisons, in which the happy couple 
live 'til death do us part. It is conceivable that death of one ends both, 
due to poisons of decay. The right-hand hole got poked twice as large driving 
the male out. I didn't know he was in there until I took another look into 
burrow in rock which I had purposely set up on end to drain and dry out 
quicker and better. What really called my attention to rock this a.m. at 
about 9:30 - 9:45 waslittle green clawed Synalpheus that had wormed his way 
out of one of the many holes to lie dead, but damp, not yet dried up, on 
surface of rock. But for the fact that I want to save the Upogebia burrow, I 
would have sought the mate to this f Synalpheus, which must still be in the rock.

Female gebia put in tow net juice, C.B. Wilson formula, for yellow tuft 
on back, which, after all, may be forced out ovaries.

stout wires beside as markers between dock and N. end of island. Also brought
