  A correlation and probability analysis of the distribution of arrival
directions for a sample of AGASA events reported to have energies above
4x10^{19} eV shows the small scale clustering to remain significant at the 99.5
- 99.9% CL and to be consistent with previous results. For the sample taken as
a whole, there are no departures from either homogeneity or isotropy on angular
scales greater than 5 degrees. The sample of events with E >= 6x10^{19} eV
possesses no small scale clustering. Cross correlating subsamples partitioned
by energy reveals three uncorrelated distributions in the intervals 4 -
5x10^{19} eV, 5 - (8-10)x10^{19} eV, and greater than (8-10)x10^{19} eV. The
partition with 5 <= E < 8x10^{19} eV is correlated with the supergalactic
equatorial plane while the other two groups are statistically consistent with
isotropic distributions. The presence of three distinct energy-partitioned
groups of events could reflect possible changes in primary composition,
different source distributions, differing levels of GZK losses, or deflection
effects of magnetic fields.
