We report experimental and numerical results from investigations into the onset of novel localized cellular states in the centrifugally stable regime of Taylor-Couette flow at sufficiently high rates of counter-rotation of the outer cylinder. Quantitative comparison is made between experimental results and those obtained from numerical bifurcation studies of the steady axisymmetric Navier-Stokes equations. The onset of the vortices is smooth but they appear over a narrow range of Reynolds number. This enables the use of a suitable measure to produce excellent quantitative agreement between calculation and experiment. The numerical methods are also used to uncover evidence for a homoclinic snake which indicates rich multiplicity in the steady solution set.
