We present results of a morphological study of galaxies from SPICES, the Spectroscopic Photometric Infrared-Chosen Extragalactic Survey. SPICES is a deep BRIzJK_s imaging and spectroscopic survey covering over 100 arcmin² spread over four fields. We have extracted a K-selected sample complete to K=20 of over 1700 objects, for which we have obtained 626 spectroscopic redshifts. In addition, we have HST WFPC2 F814W imaging in all four fields. Morphologies for 1139 objects matched between the HST and the K<20 samples are determined from the F814W imaging using various classification techniques (visual and automated). We present the evolution of the morphological mix with redshift.
