We discuss some new simple closed bosonic string solutions in AdS{sub 5}xS{sup 5} that may be of interest in the context of AdS/CFT duality. In the first part of this work we consider solutions with two spins (S{sub 1},S{sub 2}) in AdS{sub 5}. Starting from the flat-space solutions and using perturbation theory in the curvature of AdS{sub 5} space, we construct leading terms in the small two-spin solution. We find corrections to the leading Regge term in the classical string energy and uncover a discontinuity in the spectrum for a certain type of solution. We then analyze the connection between small-spin and large-spin limits of string solutions in AdS{sub 5}. We show that the S{sub 1}=S{sub 2} solution in AdS{sub 5} found in earlier papers admits both limits only in the simplest cases of the folded and rigid circular strings. In the second part of the paper, we construct a new class of chiral solutions in R{sub t}xS{sup 5} for which embedding coordinates of S{sup 5} satisfy the linear Laplace equations. They generalize the previously studied rigid string solutions. We study in detail a simple nontrivial example.
