July 28, 1924, Monday. 
Went collecting among the rocks today, east side of island and point 
north of lighthouse pier. Picked up as large pieces of coral rock and com¬ 
pacted sand (or coral) heads as I could carry and lugged them up on beach, 
where I split them open. 
Got several Eriphia gonagra by prying open deserted sea urchin holes; would 
hide 'way back in small holes so that you would wonder how they ever got in 
and out. Of course,the small Mithraxes, as usual, came in quantity. Not 
| 
so many saved this second day on the same rocks. 
Got more Crangons (several species) out of holes in rocks and several (3) 
fishes again. The C. armillatus are all tiny, with claws not over an inch 
long. 
Leptodius floridanus were all quite small and only a few on this day 
and the preceding. Squillas were, as usual, the most common crustaceans living 
in the holes. In rocks and on reef got grey, various shades of green, and 
brown. The rose red and bright yellow ones belong to the dredge hauls. 
Crangons run several to a large PhOla hole—l^" diameter at bottom almost. 
Dr. Longley and Bender collected on Bird Key Reef. Got at least a dozen 
Leptodius floridanus , all sizes, and as many Microphrys bicornutus decoratus , 
which Bender is trying experiments on, and several (two) smaller Mithrax 
spinosissimus , small, red, fuzzy, and spiny. Bender had a few Mithraxes and 
one Xanthid that resembles them, but with long arms. 
Reef crabs seem much like rocky ledge crabs on Loggerhead, but run 
larger in size. Live in interstices between rocks rather than dependent on 
Pholad and worm holes or BsxssiBBsly occasionally deserted sea urchin holes. 
These crabs] run large on the reef, though I got Crangon formosus large both 
places.
