Using images from Sloan Digital Sky Survey Data Release 8, we havere-examined the morphology of 719 galaxies from the Analysis of theinterstellar Medium in Isolated GAlaxies (AMIGA) project, a sample consistingof the most isolated galaxies that have yet been identified. The goal is tofurther improve the classifications of these galaxies by examining them in thecontext of the Comprehensive de Vaucouleurs revised Hubble-Sandage (CVRHS)system, which includes recognition of features that go beyond the original deVaucouleurs point of view. Our results confirm previous findings that isolatedgalaxies are found across the complete revised Hubble sequence, withintermediate to late-type (Sb-Sc) spirals being relatively more common.Elmegreen Arm Classifications are also presented, and show that more than 50%of the 514 spirals in the sample for which an arm class could be judged aregrand design (AC 8,9,12). The visual bar fraction for the sample is ~50%, butonly 16% are classified as strongly-barred (SB). The dominant familyclassification is SA (nonbarred), the dominant inner variety classification is(s) (pure spiral), and the dominant outer variety classification is no outerring, pseudoring, or lens. The Kolmogorov-Smirnov test is used to check forpotential biases in the morphological interpretations, and for any possiblerelation between rings, bars, and arm classes with local environment andfar-infrared excess. The connection between morphology and stellar mass is alsoexamined for a subset of the sample.
