  The construction and the symmetries of Chern-Simons vortices in harmonic and
uniform magnetic force backgrounds found by Ezawa, Hotta and Iwazaki, and by
Jackiw and Pi are generalized using the non-relativistic Kaluza-Klein-type
framework presented in our previous paper. All Schr\"odinger-symmetric
backgrounds are determined. (10 pages. PlainTex)
