A growing body of observational evidence suggests that the luminosity,photometric shape and amount of rotational or anisotropical support inelliptical galaxies may provide vital clues to how they formed. Ellipticalgalaxies appear to fall into two distinct categories based on these parameters:bright, boxy shaped, with little or no rotation, and less luminous, diskyshaped with significant rotation. One viable formation scenario is the ``Mergerhypothesis,'' in which two disk galaxies merge to form a new elliptical galaxy.A comparison of the luminosity, photometric shape, and amount of rotation inadvanced merger remnants may shed more light on the possible formationscenarios of elliptical galaxies. Yet, little observational data exists forsuch merger remnants. This paper is the third in a series investigating thephotometric and kinematic properties of a sample of 51 optically selectedadvanced merger remnants. Presented here are K-band isophotal shapes andspatially resolved kinematics for a sub-sample of 37 merger remnants. Theresults show that ~ 11% of the sample are boxy, and anisotropically supportedwhile ~ 47% are disky, and rotationally supported. The remainder of the sampleshow variations among expected correlations between shape and rotation. Thismay suggest that the isophotal shapes are still ``in flux.'' There does appearto be a lower limit to the amount of anisotropy observed in the mergerremnants. This may provide an observational diagnostic for discriminating amongformation scenarios in elliptical galaxies.Comment: Accepted A
